Description

  The present invention relates to an optical disc recording method, an optical disc recording program, and an optical disc recording device for forming, appending, and duplicating a visible image on a data recording surface of a recordable optical disc.

  A recordable optical disc can record data optically by irradiating a laser beam, and can be recorded once such as a CD-R, DVD-R, etc., a recordable optical disc, a CD-RW, a DVD- There are rewritable optical disks such as RW, DVD + RW, DVD-RAM, etc. that can rewrite data.

  In a write once optical disc, when the organic dye layer (recording layer) is irradiated with laser light, the organic dye layer is melted by the heat of the laser light to form pits. Data is recorded on a write-once optical disc using this characteristic. In a rewritable optical disk, when the recording layer is irradiated with laser light, the state of the recording layer changes to an amorphous (amorphous) state or a crystalline state due to the heat of the laser light, and corresponds to a pit or land. To be formed. Data is recorded on a rewritable optical disk using this characteristic.

  As described above, in the recording type optical disc, since the pit is formed in the portion where the data is recorded by irradiating the laser beam, the reflectance of light is different between the portion where the data is recorded and the portion where the data is not recorded, Further, color shading occurs on the recording surface. By utilizing this characteristic, the data recording surface of the recordable optical disk is irradiated with laser light, and characters, symbols, pictures, photographs, and the like are visible in a desired shape (hereinafter referred to as a visible image). Can be formed. If, for example, information relating to the recording data is displayed as a visible image on the data recording surface of the recording optical disc, it is not necessary to hand-write or print information relating to the recording data on the label surface of the optical disc. The recorded content of the optical disc can be determined.

  A conventional optical disc recording apparatus forms a visible image on a recordable optical disc by the following procedure.

  1. When an optical disk is set, the optical disk recording apparatus first determines whether data can be physically recorded, that is, whether it is a read-only optical disk such as a CD-DA or CD-ROM, Check if the disc is a recordable optical disc such as a CD-RW.

  2. The optical disc recording apparatus stops the visible image forming process when the set optical disc is a read-only optical disc. On the other hand, when the set optical disk is a recordable optical disk, the optical disk recording device confirms TOC (Table Of Contents) information or PMA (Program Memory Area) temporary TOC information, and acquires the end position of the data area. . At this time, in the case of an optical disk without TOC information or temporary TOC information, that is, a blank disk on which no data is recorded, the optical disk recording apparatus stops the visible image forming process.

  3. When a visible image can be formed on an optical disc, the optical disc recording apparatus performs editing or conversion of the image formed as the visible image automatically or according to a user instruction.

  4). The optical disk recording device forms a visible image in an unrecorded area after the end of data recording when a user gives an instruction to form a visible image on the optical disk. At this time, the optical disc recording apparatus does not form a visible image as data that can be read later, such as an EFM (Eight to Fourteen Modulation) modulated RF signal, but forms a visible image so that it can be recognized as an image. To do.

  5. When forming another visible image on another recordable optical disk, the optical disk recording apparatus does not store data (original data or data for writing) related to the visible image formed on the optical disk immediately before. Perform the process.

  The conventional optical disc recording apparatus that forms a visible image on a recordable optical disc by the above procedure has the following problems.

  (1) In the conventional optical disk recording apparatus, a visible image can be formed on a recordable optical disk capable of additionally recording data (recordable optical disk not closed). In addition, information on the visible image formation range is not recorded on the optical disk on which the visible image is formed. For this reason, when another data is additionally recorded after forming a visible image on an optical disc that has not been closed, another data may be overwritten on the formed visible image. In other words, the optical disc recording apparatus cannot grasp the visible image forming range because the information related to the visible image forming range is not recorded on the optical disc as described above, and the recording data amount and the position where the visible image is formed. Depending on the case, there is a possibility that data is recorded even in a region where a visible image is formed. In this case, the visible image and the recording data overlap with each other, and it becomes impossible to read the recording data of that portion.

  (2) The conventional optical disk recording apparatus has a problem that a visible image cannot be formed on a blank disk on which TOC information or provisional TOC information is not recorded. Therefore, when a user intends to form a visible image on a blank disc, the user has to record arbitrary data before forming the visible image.

  (3) In the conventional optical disk recording apparatus, when forming a visible image, the data for visible image is created every time and the original data for visible image and the data for writing are not stored. There is a problem that it cannot be formed on other optical discs.

  (4) Since the conventional optical disk recording apparatus does not record a visible image as an EFM-modulated RF signal such as music data or computer data, the visible image data formed on the optical disk is completely read out. I could not. Further, since the visible image is not recognized as data, there is a problem that the visible image cannot be duplicated from one optical disc to another optical disc.

  (5) Since the conventional optical disk recording apparatus does not record information on the visible image formation range when forming a visible image on the optical disk, once the visible image is formed, the optical disk recording device is placed on the outer periphery of the optical disk on which the visible image is formed. There is a problem that even if an unrecorded area remains, there is a possibility that the visible image cannot be additionally written without overlapping with the already formed visible image. For this reason, a conventional optical disk recording apparatus can usually form a visible image on an optical disk only once.

  Therefore, the present invention solves these problems, and an optical disc recording method and optical disc capable of forming, appending, and duplicating one or more visible images on an arbitrary recording optical disc having an area where a visible image can be formed An object is to provide a recording program and an optical disk recording apparatus.

  The present invention has the following configuration as means for solving the above problems.

(1) An optical disc recording method for forming a visible image of a desired shape using a process of recording information by irradiating a data recording surface of an optical disc with laser light to form pits,
Laser light irradiation pattern information, which is laser light irradiation control information obtained by converting image data in a polar coordinate system with the center of the optical disk as the origin, for forming the visible image on the data recording surface of the optical disk together with the visible image is the same. To the other optical disc.

In this configuration, a laser beam irradiation control information obtained by converting image data in a polar coordinate system with the origin at the center of the optical disk to form a visible image on the data recording surface of the optical disk and the visible image on the data recording surface of the optical disk. The laser beam irradiation pattern information is recorded and formed. Therefore, since the visible image formed on the optical disk is not recorded with the EFM signal, it is difficult to copy it to another optical disk as it is. However, when the visible image is formed on the optical disk, laser light irradiation is performed together with the visible image. Since pattern information is recorded, if you want to duplicate this visible image to another optical disk, read the laser beam irradiation pattern information recorded on the original optical disk and perform image conversion based on this laser beam irradiation pattern information. As a result, a visible image can be quickly formed on another optical disk.

  (2) After the laser beam irradiation pattern information is recorded, the optical disk is set in a recording complete state and cannot be additionally recorded.

  In this configuration, when the visible image is formed on the optical disc, the laser light irradiation pattern information is recorded, and then the optical disc is set in a recording complete state and cannot be additionally recorded. Therefore, the laser beam irradiation pattern information can be read as normal data.

  (3) After the optical disk is in a recording complete state and cannot be additionally recorded, the laser beam irradiation pattern information is recorded in an empty area of the optical disk.

  In this configuration, when a visible image is formed on the optical disc, the optical disc is recorded in a recording complete state, and additional recording is impossible, and then laser beam irradiation pattern information is recorded in an empty area of the optical disc. Therefore, since the laser beam irradiation pattern information cannot be read by a normal optical disk recording / reproducing apparatus and can be handled as hidden information, the laser beam irradiation pattern information recorded on the optical disk can be used only by a specific optical disk recording apparatus. It is possible to read out and form a visible image.

  (4) Information including the visible image formation start address and the visible image formation end address is recorded on the optical disk on which the visible image is formed.

  In this configuration, since the information including the visible image formation start position address and the visible image formation end position address is recorded on the optical disk forming the visible image, the visible image formation range from the formation start position to the formation end position is recorded. Thus, even when a plurality of visible images are formed, the visible images can be formed without overlapping. In addition, even when data is recorded after forming a visible image on an optical disc that is not in a recording complete state, the visible image formation range can be confirmed, so that the already formed visible image and the data to be added do not overlap. It becomes possible to record as follows.

  (5) The image data in the orthogonal coordinate system of the visible image is further recorded on the optical disk forming the visible image.

  In this configuration, in addition to the laser beam irradiation pattern information, image data in the orthogonal coordinate system of the visible image is recorded on the optical disk forming the visible image. Here, the orthogonal coordinate system image data is obtained by saving orthogonal coordinate system image data suitable for display on a screen of a display device such as a personal computer in a file format. For example, it is image data in a file format such as bmp format, gif format, jpg format, tif format, pct format, dxf format. Therefore, it becomes possible to promptly display the information of the visible image on the display unit of the optical disc recording apparatus.

(6) An optical disc recording method for forming a visible image of a desired shape using a process of irradiating a data recording surface of an optical disc with laser light to form pits and recording information,
Along with the visible image, laser light irradiation pattern information, which is laser light irradiation control information in a polar coordinate system with the origin at the center of the optical disk, for forming the visible image on the data recording surface of the optical disk, is recorded on the optical disk. As a result, the additional recording is disabled, and recording is performed in a free area of the same optical disc.

  In this configuration, together with the visible image, laser beam irradiation pattern information, which is laser beam irradiation control information of a polar coordinate system with the origin at the center of the optical disk, for forming the visible image on the data recording surface of the optical disk, Is recorded in a vacant area of the same optical disc after the recording is completed and recording is impossible. Therefore, when the visible image is duplicated on another optical disk or when the visible image is edited, the time for converting the data can be omitted.

(7) Using a process of irradiating a laser beam on the data recording surface of the optical disc to form pits and recording information, a visible image having a desired shape is formed on the data recording surface of the optical disc . Visible image formation information including image data is duplicated from a duplication source optical disc to a duplication destination optical disc, and the visible image is formed on the duplication destination optical disc based on the duplicated visible image formation information.

In this configuration, after the visible image formation information including the image data of the visible image for forming the visible image on the data recording surface of the optical disc is copied to the duplication destination optical disc, the visible image is formed based on the visible image formation information. It is formed on the duplication destination optical disc. Therefore, a visible image that is substantially the same as the visible image formed on the copy source optical disc can be formed on the copy destination optical disc. In addition, even if only visible image formation information is recorded on the copy source optical disc, a visible image can be formed on the copy destination optical disc by duplicating the visible image formation information. It is possible to know whether it is present or to use it for advertisements.

  According to the present invention, the following effects can be obtained.

(1) Visible image on the data recording surface of the optical disc, and laser light irradiation pattern information which is laser light irradiation control information in a polar coordinate system with the origin at the center of the optical disc for forming this visible image on the data recording surface of the optical disc Therefore, when it is desired to form this visible image on another optical disk, the laser beam irradiation pattern information recorded on the original optical disk is read and image conversion is performed based on the laser beam irradiation pattern information. A visible image can be quickly formed on another optical disk without any problem.

  (2) When a visible image is formed on an optical disc, the laser beam irradiation pattern information is read out as normal data in order to make the optical disc optically recordable after recording the laser beam irradiation pattern information. it can.

  (3) When a visible image is formed on an optical disc, the laser beam irradiation pattern information is recorded in an empty area of the optical disc after the optical disc is made in a record-complete state and cannot be additionally recorded. It cannot be read by the recording / reproducing device, but can be handled as hidden information, and the laser beam irradiation pattern information recorded on the optical disc is read only by a specific optical disc recording device, only by the recording device on the optical disc, and a visible image is formed. can do.

  (4) Since the information including the visible image formation start position address and the visible image formation end position address is recorded on the optical disk that forms the visible image, the visible image formation range from the formation start position to the formation end position is known. Even when a plurality of visible images are formed, the visible images can be formed without overlapping. In addition, even when data is recorded after forming a visible image on an optical disc that is not in a recording complete state, the visible image formation range can be confirmed, so that the already formed visible image and the data to be added do not overlap. Can be recorded.

  (5) In addition to the laser beam irradiation pattern information, image data in the orthogonal coordinate system of the visible image is recorded on the optical disc forming the visible image, so that the information on the visible image is promptly displayed on the display unit of the optical disc recording apparatus. be able to.

  (6) Along with the visible image, laser light irradiation pattern information, which is laser light irradiation control information in a polar coordinate system with the origin at the center of the optical disk, for forming the visible image on the data recording surface of the optical disk is recorded on the optical disk. Since it is recorded in a free area of the same optical disk after it cannot be added as a complete state, it is possible to save time for data conversion when copying a visible image to another optical disk or editing a visible image.

  (7) Since the visible image formation information is formed on the duplication destination optical disc based on the visible image formation information after the visible image formation information is duplicated on the duplication destination optical disc, it is almost the same as the visible image formed on the duplication source optical disc. The visible image can be formed on the optical disc as the copy destination. In addition, even if only visible image formation information is recorded on the copy source optical disc, it is possible to form a visible image on the copy destination optical disc by duplicating this visible image formation information. It can be used for advertisements.

  The optical disc recording apparatus 1 of the present invention forms a visible image by rotating an optical disc by the CAV method. Further, in the optical disc recording apparatus 1, when an azo type low-speed recording type optical disc is used, a visible image with good visibility can be formed.

  In the following description, a case where a CD-R is used as a recording type optical disk will be described. In the optical disc recording apparatus 1, the main control unit 7 reads out the program stored in the main storage unit 6, and the control unit 16 reads out the program stored in the storage unit 25. I do.

[First form]
First, the operation when the visible image is formed on the recordable optical disc in the optical disc recording apparatus 1 will be described. FIG. 3 shows the data structure recorded on the optical disc. When forming a visible image, the optical disc recording apparatus 1 closes the disc so that user data and the like cannot be added to the optical disc (the recording is completed and cannot be added), and then the visible image (denoted as visual image in the figure). 34 is formed in an empty area of the optical disk. That is, as shown in FIG. 3A, the optical disc recording apparatus 1 has the lead-in 32 and the lead for the recorded data when the data 31 is recorded on the optical disc and the optical disc is not closed. Out 33 is recorded, the session is closed, and additional recording is disabled as a recording complete state. Then, the optical disc recording apparatus 1 forms a visible image 34 in an empty area on the outer peripheral side from the lead-out 33 based on the visible image formation information stored in the main storage unit 6. As shown in FIG. 3B, when the optical disk is a blank disk, the optical disk recording apparatus 1 records the dummy session 35 and then makes the additional recording impossible as a recording complete state. Then, the optical disc recording apparatus 1 forms the visible image 36 in the empty area on the outer peripheral side from the dummy session 35 based on the visible image formation information temporarily stored in the main storage unit 6. In this case, the data 31 to be recorded on the optical disc may be user data or visible image formation information (details will be described later) which is information for forming a visible image on the data recording surface of the optical disc. Further, dummy data may be recorded in the dummy session 35, or visible image formation information may be recorded. Furthermore, the visible image can be formed at an arbitrary position.

  As described above, since the optical disc recording apparatus 1 forms a visible image after the optical disc is closed, another music data or computer data cannot be recorded after the visible image is formed. Therefore, it is possible to prevent erroneous recording of other data on the visible image. Further, in the optical disk recording apparatus 1, when the optical disk that forms a visible image is a blank disk as described above, a dummy session is recorded and the visible image can be formed after the disk is closed.

  Specifically, the optical disc recording apparatus 1 forms a visible image in the following procedure. FIG. 4 is a flowchart for explaining the visible image forming operation of the optical disk recording apparatus. Here, the optical disk set in the optical disk recording apparatus 1 is a recordable optical disk, and the description of the optical disk type determination process is omitted.

  The main control unit 7 of the optical disc recording apparatus 1 first causes the control unit 16 to confirm whether or not the set optical disc is a blank disc (s1). The control unit 16 controls each unit of the optical disc drive 2 to check whether or not the optical disc is a blank disc. If the set optical disc is a blank disc, the control unit 16 sends a signal to that effect to the main control unit 7. Output. Based on this signal, the main control unit 7 causes the display unit 4 to display a display prompting the user to select whether or not to record a dummy session (s6). If there is an input from the input unit 5 that the dummy session is not recorded on the optical disc, the main control unit 7 ends the visible image forming process. On the other hand, in step s6, when there is an input from the input unit 5 to record a dummy session on the optical disc, the main control unit 7 outputs a signal to that effect to the control unit 16. Upon receiving this signal, the control unit 16 controls each unit of the optical disc drive 2 to record a dummy session on the optical disc, thereby setting the disc closed state (s7). And the control part 16 acquires the visible image formation information which the main memory | storage part 6 memorize | stores via the main control part 7, forms a visible image in the empty area of an optical disk based on this information (s5), The visible image forming process ends.

  On the other hand, if the set optical disk is not a blank disk in s1, the main control unit 7 next checks whether the optical disk is closed (s2). If the optical disk is closed, the process of s5 is performed, and the visible image forming process is terminated. On the other hand, if the optical disc is not closed in s2, a display prompting the user to select whether or not to close the optical disc is displayed on the display unit 4 (s3). When there is an input from the input unit 5 that the optical disk is not closed, the main control unit 7 ends the visible image forming process. On the other hand, when there is an input from the input unit 5 to close the optical disk, the main control unit 7 outputs a signal instructing the control unit 16 to close the disk. Upon receiving this signal, the control unit 16 performs the processing after s4.

[Second form]
Next, the optical disk recording apparatus 1 is information for forming a visible image and the visible image on a data recording surface of the optical disk in the optical disk, the operation of setting so as to record and form a visible image forming information .

  Here, since the optical disk recording apparatus 1 forms a visible image by irradiating laser light while rotating the optical disk, the laser light irradiation pattern for visible image formed on the optical disk is created based on the polar coordinate system image. . On the other hand, a general image handled by the host computer 3 is an image of an orthogonal coordinate system. Therefore, the optical disk recording apparatus 1 converts the image data of the orthogonal coordinate system into the image data of the polar coordinate system, creates visible image formation information based on the image data of the polar coordinate system, and uses this visible image formation information to create the optical disk Record a visible image in

  In the optical disc recording apparatus 1 of the present invention, when a visible image is formed, the visible image formation information that is information for forming the visible image on the data recording surface of the optical disc is set to be recorded on the optical disc together with the visible image. Can do. That is, the optical disc recording apparatus 1 of the present invention can start recording visible image data, visible image formation start position information, visible image formation end position information, and next visible image formation information as visible image formation information. Addresses and other information can be recorded on the optical disc.

  FIG. 5 is a diagram showing an original image of a visible image, an image in an orthogonal coordinate system and an image in a polar coordinate system. The optical disc recording apparatus 1 stores the orthogonal coordinate system image data, which is the original image of the visible image as shown in FIG. 5A, in the bmp format (an example of a file format suitable for display on the screen) on the optical disc. Record. The optical disk recording apparatus 1 uses the image data of the orthogonal coordinate system to display on the display unit 4 when the user selects and processes an image formed as a visible image. Further, the optical disk recording apparatus 1 can quickly display a visible image on the display unit 4 by recording image data of the orthogonal coordinate system in the bmp format. The bmp format (orthogonal coordinate system) image data is recorded after being compressed by a predetermined data compression method.

  The optical disk recording apparatus 1 records laser light irradiation pattern information on the optical disk as data for recording a visible image on the optical disk. The laser beam irradiation pattern information is obtained by converting the image data of the orthogonal coordinate system shown in FIG. 5A to the image data of the polar coordinate system shown in FIG. 5B, and further converting the image data of the polar coordinate system into It is obtained by converting into laser light irradiation pattern information. The optical disk recording apparatus 1 can quickly form a visible image based on this information by recording the laser beam irradiation pattern information when replicating the visible image to another optical disk. The laser beam irradiation pattern information is recorded after data compression by a predetermined data compression method.

  Either one of the above bmp format image data and laser beam irradiation pattern information may be recorded as visible image formation information, but when both are recorded, the visible image is copied to another optical disc. When editing a visible image, the time for converting data in the optical disc recording apparatus 1 can be omitted.

  Further, the optical disk recording apparatus 1 records, as other information, the name of the creator of the image data, the name and version of the application software used to create the image data and visible image formation information, the creation date and time of the image data, and the like. . This makes it possible to clarify information such as the copyright owner of the visible image. For example, the visible image forming program can be set so that a visible image without such data cannot be copied.

  The optical disk recording apparatus 1 can also record the above bmp format image data and laser light irradiation pattern information on the optical disk as main channel data and other data as subcodes.

  Thus, by recording visible image formation information together with a visible image, a visible image formed on one optical disk can be easily duplicated on another optical disk. That is, as described above, the visible image formed on the optical disk is not recorded with the EFM-modulated RF signal, so that it is difficult to copy it to another optical disk as it is. However, since the optical disc recording apparatus 1 of the present invention records visible image formation information at the same time when a visible image is formed on the optical disc, it is recorded on the original optical disc when it is desired to form this visible image on another optical disc. The visible image formation information is read out, and a visible image can be formed on another optical disk based on the visible image formation information.

  Further, since the visible image formation range (from the formation start position to the formation end position) is known, even when a plurality of visible images are formed, the visible images can be formed without overlapping.

  Furthermore, even when data is recorded after forming a visible image on an optical disc that is not in a recording complete state, the visible image formation range can be confirmed, so that the already formed visible image and the data to be added do not overlap. Can be recorded.

  When the visible image formation information and the visible image are recorded / formed on the optical disc, the data structure is as shown in FIG. FIG. 6 is a configuration diagram of data recorded on the optical disc. When the optical disk is a blank disk (unrecorded disk), as shown in FIG. 6A, a session 42 in which only visible image formation information (indicated as VI data in the figure) 41 is recorded on the optical disk is provided. The disc is closed, and a visible image 43 is formed in an empty area of the optical disc. Also, as shown in FIG. 6B, a session 47 in which user data 45 and visible image formation information 46 are recorded is provided on the optical disc, the disc is closed, and a visible image 48 is formed in an empty area of the optical disc. You can also As shown in FIG. 6C, when user data 51 is recorded on the optical disc, the session 53 is closed and a session 54 in which only visible image formation information 52 is recorded is provided to close the disc. The visible image 55 can also be formed in an empty area of the optical disk.

  Next, a specific procedure in which the optical disc recording apparatus 1 forms visible image formation information and a visible image on the optical disc will be described. 7 and 8 are flowcharts for explaining the operation of the optical disk recording apparatus 1 for forming visible image formation information and a visible image. In the optical disc recording apparatus 1, it is assumed that the main control unit 7 reads a visible image recording program stored in advance in the main storage unit 6.

  When forming a visible image on an optical disc, the main control unit 7 of the optical disc recording apparatus 1 first checks whether the set optical disc can record data. Specifically, the main control unit 7 makes the control unit 16 confirm the presence / absence of a wobble signal on the optical disc, and determines whether the optical disc is a read-only optical disc or a recording optical disc (s11). When the set optical disc is a read-only optical disc, the main control unit 7 ends the visible image forming process. On the other hand, when the set optical disc is a recordable optical disc, the main control portion 7 causes the control portion 16 to confirm the recording state of the lead-in area (s12). When the lead-in area has not been recorded, the main control unit 7 causes the control unit 16 to confirm the presence / absence of PMA data (s13). When no data is recorded in the PMA, the main control unit 7 is a blank disc (s14), and therefore the display unit 4 displays a display asking whether to record user data and visible image formation information as a dummy session to the user. Is displayed (s15). When there is an input to record user data and visible image formation information from the input unit 5, the main control unit 7 first stores the user data stored in the main storage unit 6 as the first track in the control unit 16, for example. Recording is performed on the optical disc (s16). Subsequently, the main control unit 7 causes the control unit 16 to record, for example, the visible image formation information stored in the main storage unit 6 as the second track on the optical disc, close the disc (s17), and fill the empty area of the optical disc. A visible image is formed based on the visible image formation information (s18). Then, the main control unit 7 ends the visible image forming process. In this case, the optical disc has a data structure as shown in FIG.

  Further, when the main control unit 7 receives an input indicating that the user data and the visible image formation information are not recorded from the input unit 5 in s15, the main control unit 7 determines whether or not to record only the visible image formation information as a dummy session. A display for inquiring is displayed on the display unit 4 (s19). When there is an input to record only visible image formation information from the input unit 5, the main control unit 7 causes the control unit 16 to record the visible image formation information stored in the main storage unit 6 on the optical disc and close the disc. The state is set (s17), and a visible image based on the visible image formation information is formed in an empty area of the optical disc (s18). Then, the main control unit 7 ends the visible image forming process. In this case, the optical disk has a data structure as shown in FIG. On the other hand, if there is an input from the input unit 5 not to record a dummy session in s19, the main control unit 7 ends the visible image forming process.

  In addition, when data is recorded in the PMA in s13, the main control unit 7 displays a display for inquiring the user whether or not to close the session since the data is being recorded on the disc (s21). 4 is displayed (s22). When there is an input from the input unit 5 indicating that the session is not closed, the main control unit 7 ends the visible image forming process. However, if there is an input to close the session from the input unit 5, the main control unit 7 causes the control unit 16 to close the session of the optical disc (s23). Then, the main control unit 7 causes the control unit 16 to record the session of the visible image formation information stored in the main storage unit 6 on the optical disc, so that the disc is closed (s17). Further, a visible image is formed in the empty area of the optical disk based on the visible image formation information stored in the main storage unit 6 (s18). Then, the main control unit 7 ends the visible image forming process. In this case, the optical disk has a data structure as shown in FIG.

  When the lead-in area is provided in the set optical disc in s12, the main control unit 7 causes the control unit 16 to check whether the optical disc is a multi-session disc as shown in FIG. s31). Here, TOC information is recorded as subcode information in the lead-in area, and when the items in the subcode information are ADR = 5, TNO = 0, and POINT = $ B0, the disc is a multi-session disc. The main control unit 7 determines whether or not the optical disc is a multi-session disc (s32). If the optical disc is not a multi-session disc, the main control unit 7 is a single session disc that has been subjected to recording completion processing and cannot be additionally written (s33). The unit 16 is caused to perform the processing after s17 shown in FIG. In this case, the optical disk has a data structure as shown in FIG.

  Further, when the optical disc is a multi-session disc in s32, the main control unit 7 causes the control unit 16 to check whether there is a lead-in in the next session (s34). When the lead-in is recorded on the optical disc, the main control unit 7 causes the control unit 16 to perform the process of s31 again to check whether there are more sessions. On the other hand, if no lead-in is recorded in s34, the main control unit 7 causes the control unit 16 to check for the presence of PMA data (s35). When the PMA data corresponding to the optical disc is not recorded, the main control unit 7 performs the processing after s17 shown in FIG. In this case, the optical disk has a data structure as shown in FIG.

  In addition, when PMA data is recorded on the optical disc, the main control unit 7 displays a display asking whether or not to close the disc to the user, assuming that the optical disc is a multi-session disc being recorded (s36). 4 is displayed (s37). When there is an input from the input unit 5 indicating that the disc is not closed, the main control unit 7 ends the visible image forming process. On the other hand, when there is an input from the input unit 5 to set the disc closed state, the main control unit 7 puts the control unit 16 into the disc closed state, and subsequently performs the process of s18. In this case, the optical disk has a data structure as shown in FIG.

  Next, a specific procedure for determining a visible image to be formed on the optical disc by the optical disc recording apparatus 1 will be described. FIG. 9 is a flowchart for explaining a specific procedure for determining a visible image to be formed on the optical disc by the optical disc recording apparatus 1. FIG. 10 is a display example of the visible image creation program. First, as shown in FIG. 10A, the user selects the icon 61 of the visible image creation program displayed on the display unit 4 of the optical disc recording apparatus 1 and starts the visible image creation program. . When the main control unit 7 of the optical disc recording apparatus 1 detects this operation, it reads and activates the visible image creation program stored in the main storage unit 6 (s41). Then, as shown in FIG. 10 (B), the main control unit 7 sets an arbitrary character or a picture (image data in an orthogonal coordinate system) or the like to be formed on the optical disc as a visible image on the display unit 4. A display 62 prompting the user is displayed (s42). As shown in FIG. 10C, the user sets an image 63 such as an arbitrary character or picture to be recorded on the optical disc as a visible image in accordance with this display. At this time, the user may input an arbitrary character from the input unit 5 or may create an arbitrary image with image creation software. Further, character data and image data stored in the main storage unit 6 of the host computer 3 may be read. Furthermore, character data or image data may be obtained from a homepage on the Internet.

  As shown in FIG. 10D, when the image 63 in the Cartesian coordinate system is set (s43), the optical disc recording apparatus 1 is set based on the information on the free area of the recording type optical disc that has already been acquired. An image (image image of a visible image) 64 obtained by superimposing the image data on the optical disc is displayed on the display unit 4 (s44). Then, the main control unit 7 causes the display unit 4 to display a display 65 for inquiring the user whether or not to edit the visible image (s45). If the display image after the formation of the visible image displayed on the display unit 4 is acceptable, the user selects the determination button displayed on the display unit 4 and instructs the optical disc recording apparatus 1 to form the visible image. On the other hand, if there is a problem with the display image after the formation of the visible image displayed on the display unit 4, the user can change the position where the visible image is formed or adjust the size of the visible image to display the displayed image. Processing is performed (s46). When the adjustment is completed, the determination button is selected to instruct the optical disc recording apparatus 1 to form a visible image.

  The main control unit 7 of the optical disc recording apparatus 1 converts the image data of the orthogonal coordinate system set by the user into the image data of the polar coordinate system when the user gives an instruction to form a visible image (s47). Subsequently, the main control unit 7 calculates a formation start address and a formation end address when a visible image is formed on the optical disc based on the polar coordinate system image data. Further, the final address when the visible image formation information is recorded, that is, the address at which the next visible image formation information can be recorded is obtained by calculation, and the visible image formation information is stored in the main storage unit 6 (s48). Then, the visible image formation information read from the visible image formation information stored in the main storage unit 6 or the visible image formation information held by the main control unit 7 is recorded on the optical disc, and further visible based on the visible image formation information. An image is formed on the optical disc (s49), and the visible image forming process is terminated.

[Third embodiment]
Next, the operation when the optical disc recording apparatus of the present invention forms or additionally records a plurality of visible images will be described. The optical disc recording apparatus 1 of the present invention records the visible image and the visible image formation information on the optical disc as described above. For this reason, the visible image can be additionally recorded (written) on the optical disc on which the visible image is formed by the optical disc recording apparatus 1 by referring to the visible image formation information.

  FIG. 11 is a diagram illustrating a data configuration when a plurality of visible images are formed. When forming a plurality of visible images on an optical disc, the optical disc recording apparatus 1 can form a visible image with a plurality of data configuration patterns as shown in FIG. Further, as described above, the optical disc recording apparatus 1 of the present invention includes, as the visible image formation information, the image data of the visible image, the formation start position information of the visible image, the formation end position information of the visible image, and the next visible image formation information. Are recorded on the optical disc.

  Here, when forming a plurality of visible images on the optical disc, the main control unit 7 displays a session (hereinafter referred to as VIS) 1 and a visible image (denoted as VI in the drawing) 1 in which only visible image formation information is recorded. When user data is recorded at the time of recording / forming, after the disc is closed, VIS1 is recorded following the data session in which the disc is closed. As a result, the visible image formation information cannot be read out by a normal optical disc recording / reproducing apparatus, but can be handled as hidden information. The visible image formation information recorded on the optical disc is read out only by a specific optical disc recording apparatus. It is also possible to form a visible image.

  As a data configuration pattern for forming a plurality of visible images, as shown in FIG. 11A, a visible image can be formed immediately after VIS, and a plurality of VIS and visible images can be recorded and formed. The formation start position and the formation end position of the visible image to be recorded on the VIS 1 can be obtained by calculation before the visible image 1 is formed, the VIS 1 is recorded, and then the visible image 1 can be formed. In this case, since the formation end position of the visible image 1 may vary somewhat, the next VIS2 is used as an address at which recording can be started, and the formation end position information of the visible image 1 obtained by calculation is increased by a predetermined address. It is better to apply the address.

  In addition, the data amount of VIS1 is calculated in advance, the vacant area for recording VIS1 is vacated after the first session, the visible image 1 is formed, and the formation start address and the formation end address of the visible image 1 are acquired. , VIS1 can also be recorded.

  When adding a visible image, the main control unit 7 reads the previous VIS (for example, VIS1 when recording VIS2), obtains an address at which the next visible image formation information can be recorded, and from this address Record the VIS to be added. VIS3 and visible image 3 and later are recorded in the same manner.

  Further, as shown in FIG. 11B, the optical disc recording apparatus 1 can continuously record the VIS after the first session and continuously form the visible image from the outer peripheral side. In this case, the visible image 1 is formed from the inner periphery side after calculating so that the rear end portion of the visible image 1 is the outermost periphery of the formation area of the optical disc. Further, the formation start position and the formation end position of the visible image to be recorded on the VIS 1 can be obtained by calculation before the visible image 1 is formed, the VIS 1 is recorded, and then the visible image 1 can be formed. . It is also possible to record the VIS 1 after forming the visible image 1 and obtaining the formation start address and the formation end address of the visible image 1.

  When adding a visible image, the main control unit 7 reads the previous VIS (for example, VIS1 when recording VIS2), acquires an address where the next visible image formation information (VIS2) can be recorded, VIS2 is recorded from the address position. The main control unit 7 calculates the rear end portion of the visible image 2 to be the front end portion of the visible image 1 and then forms the visible image 2 from the inner peripheral side. Further, the main control unit 7 records the VIS 3 and the visible image 3 and thereafter in the same manner.

  Furthermore, as shown in FIG. 11C, VIS can be continuously recorded after the first session, and visible images can be formed sequentially from an arbitrary position to the outer peripheral side. In this case, it is necessary to set the formation start address of the visible image 1 so as to be positioned at a predetermined interval from the end of the VIS 1 so that a plurality of VIS can be recorded.

  Further, the formation start position and the formation end position of the visible image recorded on the VIS 1 can be obtained by calculation before the visible image 1 is formed, the VIS 1 is recorded, and then the visible image 1 can be formed. It is also possible to record the VIS 1 after forming the visible image 1 and obtaining the formation start address and the formation end address of the visible image 1.

  When adding a visible image, the main control unit 7 reads the previous VIS (for example, VIS1 when recording VIS2), acquires an address where the next visible image formation information (VIS2) can be recorded, VIS2 is recorded from the address position. Alternatively, the visible image 2 may be recorded after calculation so that the front edge of the visible image 2 becomes the rear edge of the visible image 1, or the visible image 2 may be recorded as shown in FIG. A slight gap may be provided between the front end portion and the rear end portion of the visible image 1. VIS3 and visible image 3 and later are recorded in the same manner.

  Specifically, the optical disc recording apparatus 1 forms and appends a visible image in the following procedure. FIG. 12 is a flowchart for explaining the visible image forming / adding operation of the optical disk recording apparatus. Here, the optical disc set in the optical disc recording apparatus 1 is a recordable optical disc. In the following description, the formation start position and the formation end position of the visible image to be recorded on the VIS are obtained by calculation before forming the visible image, the VIS is recorded, and then the visible image is formed. Details of this processing are omitted.

  The main control unit 7 of the optical disc recording apparatus 1 first causes the control unit 16 to determine whether or not the set optical disc is a blank disc (s51). If the set optical disc is a blank disc, the user is inquired whether to record a dummy session (s52). Note that the dummy session data at this time is user data or dummy data. When the user operates the input unit 5 and selects not to record a dummy session on the optical disc, the main control unit 7 ends the visible image forming process. On the other hand, when the user operates the input unit 5 and selects to record the dummy session on the optical disc in s52, the main control unit 7 causes the control unit 16 to record the dummy session on the optical disc and sets the disc closed state. (S53). Then, the control unit 16 reads the visible image formation information stored in the main storage unit 6, records the visible image formation information in an empty area (unrecorded area) of the optical disc (s58), and further forms a visible image. Based on the information, a visible image is formed in an empty area of the optical disc (s59). The main control unit 7 inquires of the user whether or not to add a visible image (s60). When the user operates the input unit 5 and selects not to add a visible image to the optical disc, the visible image forming process ends. On the other hand, when the user operates the input unit 5 and selects to add a visible image to the optical disc in s60, the main control unit 7 reads out the visible image formation information recorded immediately before and displays the next visible image formation information and Visible image formation position information is acquired (s61). And the process after s58 is performed.

  On the other hand, if the set optical disk is not a blank disk in s51, it is next determined whether or not the optical disk is closed (s54). If the optical disk is closed, it is then checked whether VIS is recorded (s55). When VIS is recorded on the optical disc, the process after s61 is performed because the visible image is additionally written. On the other hand, if no VIS is recorded on the optical disc in s55, the processing after s58 is performed.

  If the disk is not closed in s54, the user is inquired as to whether or not to close the optical disk (s56). When the user operates the input unit 5 and selects not to close the optical disc, the main control unit 7 ends the visible image forming process. On the other hand, when the user operates the input unit 5 to select the optical disk to be closed, the main control unit 7 sets the optical disk to the disk closed state (s57), and subsequently performs the processing after s58.

  Here, when determining a visible image to be added to the optical disc, the optical disc recording apparatus 1 acquires visible image formation information and free space information recorded on the optical disc when the visible image creation program is started by the user. Then, an image is displayed on the display unit 4. Further, when a visible image to be formed is set by the user, the optical disc recording apparatus 1 displays this image on the display unit 4 so as to be superimposed on the image image. Therefore, the user can set a new visible image and adjust the arrangement while confirming the image.

[Fourth form]
Next, the operation of copying the visible image by the optical disk recording apparatus of the present invention will be described. The optical disc recording apparatus 1 of the present invention duplicates the visible image formation information to another optical disc when the visible image formation information is recorded on the original optical disc when duplicating the optical disc. Based on the above, a visible image is formed on another optical disk. This makes it possible to easily duplicate a visible image that could not be duplicated conventionally. In addition, a visible image substantially the same as the visible image formed on the original optical disk can be formed on another optical disk.

  In addition, the optical disk recording apparatus 1 of the present invention replicates this visible image formation information to another optical disk even when no visible image is formed on the original optical disk and only visible image formation information is recorded. Based on this visible image formation information, a visible image is formed on another optical disk. Thereby, for example, it is possible to easily grasp which optical disk is a duplicate. Further, when an optical disc on which no visible image is formed is duplicated, a new image pattern can appear on the duplicated optical disc, and can be used for, for example, advertisement.

  FIG. 13 is a flowchart for explaining the optical disc duplication operation of the optical disc recording apparatus of the present invention. The main control unit 7 of the optical disc recording apparatus 1 first causes the control unit 16 to confirm the data recorded in each session of the copy source optical disc (s71). When the data recorded in each session includes visible image formation information (s72), the main control unit 7 temporarily stores the data recorded on the optical disc in the main storage unit 6 (s77). Then, the main control unit 7 records the data stored in the main storage unit 6 on another optical disc (s78). Subsequently, the main control unit 7 forms a visible image on the other optical disc based on the visible image formation information stored in the main storage unit 6 (s79), and ends the process.

  On the other hand, when the visible image formation information is not recorded as the data of each session in s72, the main control unit 7 subsequently determines whether or not the visible image formation information is recorded outside the data area where the recording is completed. Is confirmed (s73). When the visible image formation information is recorded outside the data area in the recording complete state (s74), the main control unit 7 performs the process of s77. Further, when the visible image formation information is not recorded outside the data area in the recording completion state in s74, the main control unit 7 temporarily stores the original optical disc data in the main storage unit 6 (s75). ). Then, the main control unit 7 records the data stored in the main storage unit 6 on another optical disc (s76), and ends the process.

  The operation for copying data recorded on the optical disc may be as follows. That is, first, after copying user data, the presence or absence of visible image formation information is confirmed. If visible image formation information is recorded, this visible image formation information is copied. Based on the visible image formation information, a visible image is formed on the copy destination optical disc.
