According to one aspect of the invention, an apparatus for recording on an optical data carrier comprises

• A device for generating a visually recognizable pattern at a physical position on the data carrier,
• • means for storing pattern information, the pattern information including at least first information indicating the physical position.

The Pattern information is like other computer-readable data usually stored in the form of markers and preferably by means of a Channel codes coded.

In According to one embodiment, the pattern information be generated in the device. An extended embodiment For example, a device may have a list of pattern information for multiple optical disks and in be able to get the correct pattern information for one specific disk based on the one on the disk present information. The advanced Device may be used, for example, for storing medical information become. In this case, the pattern information includes, for example a patient number and a date.

Preferably are the pattern information on the optical disk which has the visually recognizable pattern itself. On this way, the visually recognizable pattern on the optical Disk in another device that is capable is to read the visually recognizable pattern, slightly modified, be moved and so on.

According to one Aspect of the invention comprises an optical disk a visually recognizable pattern at a physical location the disk, the disk further Sample information includes at least initial information which indicate the physical position of the pattern.

One disk-shaped optical data carrier on the can be recorded by the present invention, for example an inner section that is completely populated with data, and an outer section that through the visually recognizable pattern is covered. The user, the additional You may want to add data to the disk first information showing the physical position of the visually Specify recognizable pattern, request and the outer Section to overwrite it with additional user data release. Alternatively, the user can decide that visually to move recognizable patterns to an inner position of the plate. In this way, this requires a visually recognizable pattern less space on the plate, so that extra too Data can be recorded on the disk. If additional second information representing the visually recognizable pattern stored, the visually recognizable pattern of these stored data to be regenerated at its new location.

Since the visually recognizable pattern on the volume may be represented at a relatively coarse resolution on the volume as compared to the resolution with which the data is stored, the area for storing the pattern information may generally be substantially smaller than the area that is occupied by the pattern itself. For example, the visually recognizable pattern may be stored at a resolution of 1 to several hundreds of dots per mm ² , while computer readable data is stored on the volume at a resolution on the order of several Mbits / mm ² . For example, the storage density for BD is up to 40M channel bits, which equates to 30M bits of user data.

In One embodiment includes the visually recognizable pattern a bitmap, where each pixel of the bitmap is in the visually recognizable Pattern replaces multiple units of data on disk, and the second information represents the bitmap with a data unit for each pixel. Since the bitmap is in a computer readable Format can be displayed with a resolution that much is higher than the resolution with which the bitmap is presented to the user as a visually recognizable pattern, is the extra space to save the second Information is required, much lower than the range, which is required for the pattern itself. The storage requirements for the first information is also limited. The first For example, information can have an inner radius and specify an outer radius within which the visually recognizable pattern is applied to the data carrier. The first information can also be an angle pair that is tangent to the rotation axis of the disk is within which the visually recognizable pattern is located. Alternatively, the position of the visually recognizable pattern be specified in rectangular coordinates. In any case only a moderate amount of data required to visually position representable pattern. While the pattern information only They require a moderate amount of storage space Substantial improvement of the possibilities that it gives you Users enable the visually recognizable pattern to move another position on the disk, to modify the content of the visually recognizable pattern.

A even more compact storage of the second information of the visually recognizable pattern is achieved when the visually recognizable pattern can be coded. Accordingly, this includes the visually recognizable Pattern in a preferred embodiment a string, wherein the second information comprises a code, e.g. An ASCI code, which represents the string.

alternative the visually recognizable pattern comprises a graphic image, the second information being a mathematical model for include the picture. The mathematical model can be for example the Picture in basic shapes like rectangles, circles, Bezier forms, splines etc. describe. The visually recognizable pattern can be a combination two or more of a string, a graphic image and a bitmap or other patterns.

It Several options are possible to get the second information to obtain. The second information becomes automatic, for example generated. For example, the second information a record date of the volume, a name of one File that exists on the disk, or a pattern, that in a memory of a device performing the method is stored.

alternative to do this, the second information may be from a user input are derived, for. B. through a dialog presented to the user becomes.

As well The first information can be generated automatically. For example, an inner ring of the volume may always be considered the position for the visually recognizable pattern is selected be.

Alternatively, the method may require user input to determine a physical location. After the user is prompted to enter the desired physical location, verify that the desired physical location is available on the media. The user input can be in a way be requested, which is known as such, for. Eg through a dialogue. If the verification reveals that the desired position is available, the visually recognizable pattern is applied at that position. Otherwise, the user can be signaled the unavailability of the position. In addition, an alternative position could be proposed.

It can have more than one visually recognizable pattern on the disk are displayed. In this case, the number of labels should also be be stored on the medium.

To the Store the second and first information every visually recognizable Patterns on the plate are numerous possibilities to disposal. The second and first information can be used for Example in a file system that is on the optical disk can be stored, or in the device, for. B. on one separate disk of the device, be arranged.

The UDF file system supported on rewritable media a structure indicating the state of the medium; she gives the Number of files, the number of directories, whether the volume dirty and so on. These data are in the integrity descriptor maintained the logical volume [Logical Volume Integrity Descriptor], which is updated every time the disk is removed from the drive is removed or the system on which it is running shuts down. This descriptor has a capacity of 2048 bytes, from which about 120 bytes are used. This leaves room for the pattern information, also referred to as label mapping data [Label Allocation Data] of about 7 text labels.

Especially explains how to get the pattern information through the drive on a DVD + RW and a DVD-RW.

The storage of DVD + RW data is described with reference to 2 illustrated. As shown therein, this medium contains a Disc Identification Zone (actually two, one on the inside and one on the outside of the recordable area) containing 15 disk control blocks (DCB) stored in an ECC block are stored. In one embodiment, one or more of these disk control blocks may be used to store the pattern information. This leaves room for the label mapping data of more than 125 text labels.

3 shows by way of example how the pattern information can be stored on a DVD-RW medium. This medium manages its state in the R information zone, more specifically in the recording management area [Recording Management Areal. This section contains 15 Recording Management Data files, one of which is reserved for user-specific data; This RMD block is used for lab administration. 7 shows this. This leaves room for the Label Allocation Data of about 7 text labels if an identifier is used to identify the labels.

In In the above examples, the pattern information is on the volume saved. Alternatively, the pattern information also in a permanent memory of the device for recording be stored on the disk.

A system, which the device 20 and a host processor 10 that is linked to, is included in 4 shown. As shown therein, the drive includes 20 a read / write head 21 to read visually recognizable information from the disk 40 and providing an output representative of the information read from the volume to an RF processing circuit 26 , The read / write head 21 is relative to the volume 40 by means comprising a spindle motor 22 to rotate the disk 40 and other means, e.g. B. a guide and a radial actuator (not shown) for the radial movement of the read / write head 21 includes, relative to the volume 40 movable. A servo circuit 23 Controls the relative movement of the read / write head 21 in terms of the disk 40 , The RF processing circuit 26 disassembles the signal coming from the read / write head 21 was obtained in a first output signal sent to a decoder circuit 27 which decodes the first output signal into a digital signal representing the data stored on the data carrier 40 are stored. The RF processing circuit provides a second output signal to an address detection circuit 29 ready, which determines the address on the disk, just by the read / write head 21 is accessed. The data by the decoder circuit 27 to be obtained and the address given by the address detection circuit 29 is determined to be the general controller 32 provided. The controller controls this information 32 the servo circuit 23 ,

The data is sent through an encoder 30 , a writing strategy unit 31 , a driver 24 and the read / write head 21 on the disk 40 written. The data to be written is through the encoder 30 coded. The encoding may include error protection coding (e.g., Reed-Solomon) and channel coding (eg, EFM coding). The encoded signal is sent to the write strategy unit 31 which computes a required modulation of a signal to be sent to the read / write head to optimally represent the coded signal. This depends on the type of data carrier used, eg. Whether the data carrier comprises an active layer based on a phase change material, a dye, etc.

The driver 24 converts the output signal into a signal suitable for driving a write device of the read / write head. Normally, the writing device comprises a laser and a lens system for providing a focused beam on the disk 40 , A laser power controller 25 further regulates the actual power applied to the writer. The laser power controller 25 monitors the intensity of the laser beam in response to the signal generated by the driver 24 and adjusts the driver to compensate for temperature changes and temporary degradation of the laser in the read / write head.

The device comprises a permanent memory 33 which is suitable for storing pattern information for multiple volumes. The host processor 10 can execute parent applications. The host processor 10 may be a separate module, but may alternatively be integrated into the device. The components in the second module 20 comprising the means for generating the visually recognizable pattern on the data carrier 40 Forms are essentially the same as those used to record computer-readable data. As with the computer readable data, the visually recognizable pattern becomes the recording layer 41 on the disk 40 by modulating an intensity of the laser beam from the read / write head 21 generated while a relative shift between the read / write head 21 and the disk 40 provided. Unlike the method for computer readable data, the signal that controls the intensity of the laser beam does not have to match the channel code for recording computer readable data. Therefore, the encoder can 30 through a bypass 35 bypassed. become.

Means for storing pattern information includes firmware in the general controller 32 allowing the second module to store the pattern information in a selected area of the volume 40 for example, in disk control blocks (DCB) of DVD + RW data as referenced above 2 illustrated, or in a RMD block of a DVD-RW, as in 3 shown. Alternatively, the means for storing pattern information may include a process performed by the host processor 10 which executes the pattern information as a user file on the optical disk 40 stores. The device is suitable for performing various tasks as claimed. The tasks may be performed by dedicated hardware, but are preferably performed by firmware running on the general controller 32 is running (for example, for subordinate tasks related to components of the drive 20 ) or through software (for example, for the parent tasks related to the application) running on the host processor 10 is performed.

Several Examples now describe in more detail z. For example writing, modifying and moving a visually recognizable pattern (label) on one optical disk.

A Another embodiment relates to the application of several Labels in case of Disc-At-Once recording. The label mapping area [Label Allocation Areal is used for this purpose (see above). This is not possible when the plate is complete is described as additional for such an operation Storage space is needed. More precisely, it is too not possible if a not completely written plate without the possibility of adding a session was finalized.

Of the User is able to put a label in any position to place on the plate, as long as the minimum radius of 27 mm is observed and as long as enough free space is available for the files that the occupy required label positions because they are being moved have to. If there is enough free space available is generated the method according to the invention a new data area or a new session to save it Files. It is to distinguish between DVD + RW and DVD-RW, since the process of generating sessions is different.

6 shows an example of a DVD + RW disc before and after applying the label. It shows the effect of data movement. A DVD + RW disc only knows the concept of lead-in and lead-out.

This section describes how to move data on a DVD-RW disc. A DVD-RW disc knows the concept of lead-in and lead-out, but also that of Border-in and Border-out. Therefore, one of the following can complete a data zone [Dato Zone]:

• • Lead-out
• • HF with lead-out attribute
• • Border-out
• • Border-out + lead-out

The However, the principle of moving data is similar to that for the DVD + RW, except for the zones to be rewritten (Lead-out or border-out) and disk management fields.

7 shows an example of a DVD-RW disc before a label is applied and after the label has been applied. It shows the effect of the data shift in the event of a border-out. If there is a lead-out on the medium, it should be shifted by the same amount as the border-out. A lead-out is shown in dashed lines as it may or may not be recorded. However, if recorded, it will be moved back by the same amount as the border-out.

8th shows a practical embodiment of a user interface for prompting a user to provide information regarding the visually recognizable pattern to be printed.

With a first checkbox (label-print enabled) the user the feature for writing a visually recognizable Enable or disable the pattern on the plate.

With a second checkbox (high contrast activated) the user can increase the visible contrast to Example by using a half as fast recording mode.

in the In the case of a rewritable medium, "data replace "to indicate whether the original data to be moved to another empty position of the disk. In the case of a text tag, this information can also be be edited because the data itself is also stored on the disk are.

Of the User can select a position for the label (first information).

The second information which the visually recognizable pattern (label) may be provided as follows by the user become.

The user can select a font, e.g. B. Arial. In most user cases, the label can be placed in any available position, but inside is preferred because it consumes less capacity per character height. Another check box (Auto-generate text) allows the user to select the option to have the label created automatically. For example, the label often contains only the disc creation data and the main file type, such as .jps, which indicates that the disc contains photos. In this case, the automatically generated label is for example: "Photos 15. March 2007 ".

If the content for the label is not automatically generated, For example, the user may specify a text: "My Text".
