Description

The invention relates to a playback or Recording device for optical recording media, with reproduced the information, data or control signals or recorded without an as Removable disk provided optical Record carriers, such as a CD or a Disc for recording information in the device is inserted and without a special electronic Memory is available.

Playback devices for optical recording media, such as for example CD players, or CD-ROM drives and Recording devices for optical recording media, such as For example, mini disc recorders, with which information can be recorded are generally known. Optical recording media are disks, plates or also cards on which information such as music, video, sound and text and data are stored or recorded can be and the contactless, preferably with a Lasers are scanned or written.

Regardless of its function as a recording or Playback medium becomes the one for exchange or exchange provided optical recording media also as called so-called removable disk.

Playback and recording devices for optical Record carriers and corresponding removable data carriers  have in private households and in public areas already widely used. CD player, CD-ROM run works and video disc players are usually supported by advertising, sold through retail. While the customer in the specialist trade usually the device demonstrated and explained with its functions and advantages the customer is buying in others Trade facilities or the first time the Device usually on an extensive study of the Instruction manual instructed. Will be a device or certain functions of the device over a longer period Period not used, they are forgotten and the operating instructions must be taken up again. Good advice is expensive when the user guide misplaced or even lost, which means that the Enjoyment of the purchased device can be diminished. With an optical recorder Record carriers can only contain information or data then be saved when performing the Record required operating functions known the corresponding removable disk is available and a corresponding storage capacity is available stands.

It is therefore an object of the invention a reproduction or Recording device for optical recording media too create that for playback or, if necessary, for Recording information or data is appropriate without a removable disk, an instruction manual or a special electronic circuit for Information storage is in place.

This task is accomplished with the in independent claims specified features solved. Advantageous training and Developments are specified in dependent claims.  

The invention assumes that the playback or Recording device for optical recording media in Device contains an information or data storage in for example the instruction manual or others Information or data are stored or can be saved. Such information can for example: an interactive self-declaration of the Device or components to be connected, a so-called Device demo, device tests, customers or dealer information, Advertising, device explanations, otherwise from the dealer troubleshooting information or Device setting and by an operator of the device recorded information or data. For However, information storage is neither one in the device Removable disk to be inserted is a special one electronic circuit provided and yet the playback or recording of data or Allows information or device demonstrations.

According to the invention is a playback or Recording device for optical recording media for Holding the removable medium provided holding device designed as an optical recording medium. In a CD game Such a holding device is, for example, a so-called puck, with which the CD on the turntable is held. One corresponding to this puck Holding device is used as an optical recording medium trained and is used as a memory for the above Information or data used. In playback or The recording device is an optical recording medium provided that the no removable disk but a fixed one Is part of the device. One on this optical Operating instructions can be stored in the recording medium not get lost and is in the recorder additional storage space available. The playback or  Recording device for optical recording media is still for use with removable media Unrestricted use, as it is already in the device existing functional element not or only insignificantly regarding its function for the removable disk is changed.

To play or record information or Data with the optical built into the device Record carrier is preferably also in the Playback or recording device for the Removable disk provided scanning or Recording system used.

In playback or recording devices for optical It is necessary to record with a record carrier Fix the fixture on the platter. This takes place in numerous devices with a magnet that is in a plastic part is attached and from above on the Record carrier is placed. This holding device will referred to as a so-called puck. The puck respectively the plastic part is when, for example, no CD in the Device is inserted directly on the turntable. The As a result, the scanning system finds no record carrier and after several attempts, the device signals that Focus light beam on the record carrier that no CD is inserted.

According to the holding device the puck that comes from the turntable even when not inserted optical recording medium is driven as optical recording medium. The Holding device has an optical recording medium on which, in contrast to the removable disk, is a component of the device. Preferably one is the scanning or  Side of the holding device facing the recording system, whose area may be enlarged, as optical recording medium. That in Playback or recording devices existing scanning or Recording system is then used for both Removable data carriers provided optical recording media as well as for the intended as part of the device optical recording medium used.

The related to the holding device or in connection with the puck optical recording medium is, for example, via a Adhesive connection put together with the holding device or it is a snap connection between the puck and the optical Record carrier provided. The optical one The record carrier is therefore also available as a puck CD designated. However, it can also be any other type of connection chosen or the holding device as one piece optical recording media are formed.

The scanning or recording system in the device The diameter of the puck CD can be used preferably to the playback or recording area adapted to the playback or recording device. As optical recording medium provided area of Holding device is read with the scanner or it is information with a recording system or data saved. Reading or recording Information or data is preferably done when a as Removable disk provided optical Recording medium is not inserted in the device. The puck CD is then in a position to scan or Brought recording system, which is analogous to the usual Position of the removable disk in the playback or Recording device. However, the application is not on such an embodiment is limited because, for example  a second scanning or recording system, the puck CD read or even with a removable disk inserted can be described.

The optical provided as part of the device Recording medium or the puck CD is preferably a memory for playback or recording of information or data of the type specified above there is no additional electronic memory in the Playback or recording device needed and it can nevertheless acoustic, visual or functional Information such as a spoken version the instruction manual, a demonstration of the functions of the device, advertising, music, etc. are reproduced. Also different language versions can be found on the Record carriers are saved so that a version of the record carrier for different countries can be used. On the record carrier stored subcode information can be used to on a display or screen of the device or one connected device to display text or graphics. The Device can explain itself and the dealer would need less time to perform the functions of the device to explain. How to troubleshoot or Correction of incorrect settings can be given. Devices with such an information medium are equipped, make it possible for everyone Get to know the functions of the device, the one cannot read written operating instructions or would like to. The functions of the device can also be used without Removable media can be checked. It can be a Interactive system can be created with one operator will give the opportunity by asking which on the record carrier as spoken information stored, press buttons on the device, which then  the further sequence of operation or the desired one Influence function. This can deepen the learning effect the operator can be informed of the confirmation be that the information previously communicated is correct was understood. It is still possible on the puck CD To accommodate information and music with which Operator, for example, setting and connecting the Speaker is explained. In particular multi-channel Sound systems can thus be optimally adjusted. Each after how detailed and extensive the information are designed on the record carrier, the usual operating instructions can be replaced. One on this Operating instructions built into the device do not get lost. The user can then no longer happen that he misplaces the instruction manual or loses, and thus the exact description of the device and whose functions are lost.

In addition, the puck CD can be used for storage Recording and reproduction of information or data be. The puck CD is then one or more times writable optical recording medium is formed. It then there is the possibility of information or data save without an additional in the device Memory circuitry is required. In this version can be designed as an optical recording medium Holding device as an individual information or Data storage can be used.

Playback or recording devices for optical Record carriers are, for example, CD players, so-called WORM devices, mini disc playback and Recording devices, video disc playback and Recording devices, card readers, CD-ROM drives, DVD-Ab game or recording devices and the like. How  this list already shows the area of application the invention by the nature of the optical Media limited.

Preferably, the has as part of the device provided optical recording media a format, that matches the format of the removable media. It is also advantageous, for example one smaller diameter compared to removable media to ensure the inertia of the system is not significantly increase. The puck CD can be, for example, one with a Single CD conforming format or one of them have a different shape. The peculiarity of the However, the record carrier is that the optical Record media in contrast to removable media as Device component is provided. However, this excludes not that the intended as part of the device optical recording media, such as in the case a snap connection between the holding device and the puck CD, is also interchangeable.

Playback or equipped with a puck CD Giving recording devices for optical recording media after pressing the power button or one Service switch information, data or control signals again or record information without an as Removable disk provided optical Record carriers, such as a CD or a Disc for recording information in the device is inserted and without a special electronic Memory is available.

It is still an advantage of having a puck CD equipped devices that the time to recognize the Condition that there is no removable disk in the device  is reduced. When not in the device inserted removable disk, the light beam on the Focused puck CD. Data read from the puck CD can then for a decision - no removable disk in the Device - can be used. A multiple focus is then not necessary.

A built-in device is advantageous Operating instructions for numerous functions Devices such as one with a known one VCR comparable DVD player and Recording device that has the programming of a known video recorders additional functions, such as for example, viewing an action by different shooting positions and numerous others Features that result from the application of a optical recording medium with short access time and of digital signal processing.

The invention is described below with reference to Exemplary embodiments illustrated in drawings. Show it:

Fig. 1 Sketch of a device with a puck CD,

Fig. 2 sketch of an apparatus with a puck CD and removable media,

Fig. 3 Schematic representation of a known device for removable media and

Fig. 4 Schematic representation of a device with a puck CD and with and without a removable disk.

In the figures, reference numerals with the same Meaning used.  

Fig. 3 shows the schematic representation of a known device of a playback or recording device for removable media 1 , 1 a, as it is used for example in CD players. The term removable disk is not only used to indicate that the device or the device is suitable for a single CD 1 a with a diameter of 80 mm as well as a conventional CD 1 with a diameter of 120 mm. It is also intended to express that the optical record carrier is provided by simple handling for the exchange or exchange of record carriers of the same type, but carrying different or the same information or data. This can be, for example, different CD's with classic or popular music or different feature films for DVD or video disc. Removable data carriers are also optical recording media in the form of cards or optical recording media with the properties of a ROM or RAM.

The illustrated in Fig. 3, known apparatus of a reproduction or recording device for exchangeable data medium 1, 1a comprises a holding apparatus 2, which is formed by a so-called puck. The holding device 2 is fastened with a puck holder 3 in a device flap (not shown) or in a housing (not shown) and contains a magnet 4 . The magnet 4 is provided for clamping the removable data carrier 1 , 1 a on the turntable 5 , which is arranged opposite the holding device 2 . To center a removable data carrier 1 , 1 a on the turntable 5 , the turntable 5 has a centering means 6 , which is preferably formed by a cone or a spherical segment. The removable data carrier 1 , 1 a is placed on the turntable 5 , centered with the centering means 6 and held on the turntable 5 with the puck provided as the holding device 2 . For this purpose, either the turntable 5 with the removable data carrier 1 , 1 a to the holding device 2 or the holding device 2 is guided to the turntable 5 . The holding force for clamping the removable data carrier 1 , 1 a is generated in this embodiment with the magnet 4 , which interacts with corresponding elements of the turntable 5 , which are not shown. Also not shown is a scanning or recording system of the playback or recording device, which is usually also arranged in relation to the removable data medium 1 , 1 a on the side of the turntable 5 . The turntable 5 , the removable disk 1 , 1 a and the holding device 2 are driven in a known manner with a drive shaft 7 of a motor, not shown. Clamping the removable data medium 1 , 1 a on the turntable 5 is necessary because both the weight of the optical recording medium similar to a CD 1 and the support surface on the turntable 5 are not sufficient to fix the recording medium or in the case of rotating recording media in corresponding revolutions to move.

According to the invention, the holding device 2 or the so-called puck FIG. 4 accordingly has an optical recording medium 8 , which is also referred to below as a puck CD. The designations of optical recording medium 8 and puck-CD are used synonymously in the following in order to enable a simple distinction between the optical recording medium provided as removable data medium 1 , 1 a and the optical recording medium 8 provided as puck CD. In accordance with FIG. 4, the optical recording medium 8 forms a structural unit 28 with the holding device 2 , which in this embodiment is produced with a snap-in connection. Fig. 1 and Fig. 2 in accordance with, the structural unit 28, for example by an adhesive bond between the holding apparatus 2 and the puck CD can be produced. The puck CD thereby becomes an optical recording medium 8 provided as a component of the playback or recording device. This means that an optical recording medium 8 is also present in the playback or recording device, although no optical recording medium provided as a removable data medium 1 , 1 a has been inserted into the device. This corresponds to the illustration on the right in FIG. 4. Corresponding to this part of FIG. 4, the puck CD is lowered to the level of the turntable 5 , as a result of which the puck CD becomes a scanning or recording system (not shown) of the playback or recording device the removable disk 1 , 1 a assumes the corresponding position. The scanning or recording system can thus be used advantageously for the removable data medium 1 , 1 a as well as for the puck CD. This correspondence is illustrated by a comparison of the right-hand representation with the left-hand representation in FIG. 4.

According to an embodiment not shown, the turntable 5 can also be brought up to the holding device 2 when the removable data medium 1 , 1 a is not inserted. Since the turntable 5 and the scanning or recording system are generally arranged on a common chassis, a matching positioning of the scanning or recording system to the puck CD and to the removable data medium 1 , 1 a is achieved even with such an embodiment.

Fig. 1 and Fig. 2 show an exemplary embodiment with further details. In Fig. 1, a holder 2 with a rotatably mounted in a housing, not shown puck holder 3, designed as a puck CD optical recording medium 8 having a CD corresponding to an initial portion 8a and an end region 8 b and a turntable 5 are connected a centering means 6 , which consists of a cone 6 a and a cylinder 6 b, is shown. A removable disk 1 , 1 a is Fig. 1 is accordingly not inserted into the playback or recording device, so that the holding device 2 rests directly on the turntable 5 . An offset in revolutions turntable 5 then drives with a holding force between the holding apparatus 2 and turntable 5 likewise on the holder. 2 The holding force can be generated according to the aforementioned design using magnetic means or mechanical means. The puck CD, for example connected by an adhesive connection to the holding device 2 , is thereby set in revolutions and is read or written with a scanning or recording system, not shown, analogously to a removable data medium 1 , 1 a. For reading or recording data or information, the puck CD with the holding device 2 is centered on the turntable 5 . The exact centering of a rotating optical recording medium is necessary for reading or recording data or information so that the scanning or writing beam can follow the track of the optical recording medium. According to FIGS. 1 and 2, a centering means 6 is therefore provided that consists of a cone 6 a and a cylinder 6 b. This centering means 6 advantageously ensures both the centering of the holding device 2 and the centering of the removable data carriers 1 , 1 a. While the holding device 2 or the puck CD can be centered both with a cylindrical and with a conical centering means 6 , centering the holding device 2 is at a greater distance from the turntable 5 with a cone 6 a due to the inserted removable data medium 1 , 1 a not possible. As shown in FIG. 2, the distance between the holding device 2 and the turntable 5 also results in a distance between the conical area of the holding device 2 and the conical area of the centering means 6 . The removable disk 1 is centered on the turntable 5 with the conical area of the centering means 6 . To avoid an imbalance by the holding device 2 , the centering of the holding device 2 to the turntable 5 is required even when a removable data medium 1 , 1 a is inserted. In order to center the holding device 2 despite an increased distance from the turntable 1 , 1 a to the turntable 5 , a cut of the centering means 6 directed towards the holding device 2 is therefore shaped as a cylinder 6 b and the holding device 2 has a shape and size of the centering means 6 corresponding recording. The puck CD has FIGS. 1 and 2 in accordance with a smaller diameter than the exchangeable data medium 1, whereby a smaller diameter of the puck CD in comparison with the exchangeable data medium 1 can be viewed with a correspondingly smaller memory space requirement due to the smaller mass to be advantageous. The diameter of the start area 8 a of the puck CD is preferably selected to match a start area 1 s of the removable data carrier 1 , while the diameter of the end area 8 b of the puck CD can be chosen to differ from the diameter of the end area 1 e of the removable data carrier 1 .

Playback or recording devices equipped with a puck CD for optical recording media reproduce information, data or control signals or record information after pressing the power button or a service switch without having to use an optical recording medium, such as a removable data carrier 1 , 1 a CD or a disc for recording information is inserted in the device and without special electronic memory.

On the puck CD, for example, advertising or the Operating instructions must be saved in spoken form. If someone without a plate or one insert the optical recording medium into the device Press the play button, he gets the in different languages Request the title corresponding to his language to visit and then there the corresponding explanations to get the device he bought, for example 1-German, 2-English, 3-French, 4-Italian or other. Music tracks can also be stored on the puck CD be, the particular audio qualities of the device particularly show off well, such as Bass Boost and Surround sound effects. If the device is part of a compact Attachment, the information can also affect the others Obtain parts of the device, such as tuner, tape or amplifier.

Devices equipped with a puck CD also make it possible to get to know all functions of the device that an enclosed written instruction manual is not can read or want to read.

An interactive system can be created with the puck CD will. It can give the user the opportunity to go through Prompts spoken on the CD are keys to press on the device, which then the further course of the  Affect user information. So the learning effect be deepened or it can give the user confirmation be communicated that the information previously communicated was correctly understood.

The playback or recording device can also be designed such that the function of the device is explained to the operator when a removable data medium 1 , 1 a is not inserted and a button on the device is pressed.

With the subcode of a puck CD, information can be sent to the Microprocessor, which are preferably passed on an alphanumeric display passed on to the user will. In the norm for the recording of the CD are in Subcode channels R through W inclusive for such purposes intended. Channel Q, on the other hand, becomes used to the track number and the corresponding Transmit time information. Is also through that Transmission of information via the subcode Possibility created in addition to the acoustic Information to transmit control signals, for example controls the backlighting of buttons and symbols. This Means can be used, for example, to Prompt user for pressing these buttons, or him to tell which function the corresponding glowing or flashing key.

Through appropriate formulations of the information it is conceivable that a universal puck CD is recorded, the explains all device functions to the user, but on it indicates that not every device fulfills all functions can. This would make it unnecessary to create something new for everyone appearing device to make a new puck CD, thereby with an increasing number of those required for device manufacture Puck CD's, the price of which is reduced.  

Depending on how detailed and extensive the Information on the puck CD, they can replace written operating instructions. The user then it can no longer happen that he the Operating instructions misplaced or lost, and thus the exact description of the device and its functions get lost.

The puck CD can be in many different ways used and designed so that the field of application and the practice of the invention is not limited to that here specified embodiments is limited.
