The drive unit (300) of a recording device (100) of this invention is provided with a drive controller (320) that, upon receiving a write command indicating that data should be written to a specific area of the specified disk, writes the data to a memory unit (340) and records an association between the area of the memory unit (340) to which the data was written and the specific area of the specified disk. When the specified disk is inserted, the drive controller writes, to the specific area of the specified disk, the data which had been written to the memory unit (340), and also sends a "data write complete" notification to the issuer of the write command.

Description

  The present invention relates to a drive device that includes a non-removable recording medium and can be loaded with a removable recording medium, a synchronization method in the drive device, and a content recording / reproducing device including the drive device.

  Along with the spread of television receivers capable of high-definition display such as so-called full high-definition, a recorder apparatus capable of mounting a Blu-ray disc (BD) capable of recording large-capacity data such as full high-definition programs is also widely used. doing.

  A recorder device capable of mounting an optical disc such as a BD does not include a type (hybrid recorder device) having a built-in hard disk capable of recording a larger amount of data than an optical disc, and such a hard disk. It can be roughly divided into types (straight recorder devices).

  Since the straight recorder device records the recorded content (program) on the optical disk loaded in the recorder device, the recorder device can be operated by the same operation method as a conventional recorder device such as a video deck. . However, when an optical disk is not loaded and when the data capacity of the mounted optical disk is insufficient, content cannot be recorded, and content recording failures increase. In addition, since an optical disk having a data reading speed and writing speed inferior to those of a hard disk is used, the user is likely to feel stress in the operation response.

  In the hybrid recorder device (for example, Patent Documents 1 and 2), recording and playback using a hard disk whose data reading speed and writing speed are faster than those of an optical disc are possible, and the user does not feel stress in the operation response. Few. That is, the hybrid recorder device solves the problems of the straight recorder device described above.

  However, for users who are unfamiliar with the hybrid recorder device such as the elderly, it is difficult to understand the concept that the content (program) is recorded on the hard disk, and thus the operation method of the hybrid recorder device is often not understood. In addition, when content is played back on another device, processing for copying the content recorded on the hard disk to the optical disc occurs. In this case, since it is necessary for the user to select an optical disk on which the content is to be recorded and to be loaded into the recorder device, there is a problem that a mistake such as recording the content on the optical disk unintended by the user occurs. .

  In Patent Document 3, when a designated optical disc is not loaded, the content is recorded on the hard disk (HD), and when the designated optical disc is loaded in the drive, the content recorded on the HD is designated. A hybrid recorder device for dubbing to an optical disc is disclosed.

Japanese Patent Publication “JP 2007-234137 A” (published on September 13, 2007) Japanese Published Patent Publication “JP 2005-50395” (published February 24, 2005) Japanese Patent Publication “JP 2007-517344” (released on June 28, 2007)

  According to the hybrid recorder apparatus described in Patent Document 3, it is possible to execute reserved recording regardless of whether or not a designated optical disk is loaded. However, the hybrid recorder device described in Patent Document 3 has the following problems.

  The hybrid recorder device refers to the HD file system for contents recorded on the HD, and refers to the file system of the loaded optical disk for the contents recorded on the loaded optical disk. . Since the file system of the loaded optical disk is deleted when the optical disk is removed from the optical disk drive, the hybrid recorder device cannot refer to the file system of the optical disk when the optical disk is not loaded. .

  Therefore, in the hybrid recorder device described in Patent Document 3, when the optical disk is not loaded, the content recorded on the optical disk cannot be accessed by referring to the file system of the optical disk. That is, even if a certain content can be recorded on the hard disk as a content to be written on a certain optical disc, the content can be processed as a component of a file system on the optical disc until the optical disc is loaded. Can not. For example, until the optical disk is loaded, the directory for storing the content cannot be determined in the file system on the optical disk.

  Therefore, in the hybrid recorder device described in Patent Document 3, when performing dubbing processing from an HD to an optical disc, content recorded as a constituent element of the file system on the HD is used as a constituent element of the optical disc file system. As a result, it takes a long time to copy the content. Also, until the optical disk is loaded, it is impossible to specify how much free space is available on the optical disk, so large content that cannot be written to the optical disk is recorded on the hard disk as content to be written to the optical disk. Problems such as

  Furthermore, in the hybrid recorder device described in Patent Document 3, in order to write the content recorded on the HD onto the optical disc, it is necessary to supply a command to write the content from the HD onto the optical disc. That is, in the hybrid recorder device described in Patent Document 3, two write commands, that is, a write command to the HD at the time of recording and a write command to the optical disc at the time of writing from the HD to the optical disc must be supplied. There is a problem that the burden on the apparatus becomes large.

  Further, in the hybrid recorder device described in Patent Document 3, when the hybrid recorder device is powered on or there is content recorded as substitute in the HD, it is urged to attach the designated disc. In this case, for example, for a user who wants to view content other than the content that has been reserved and recorded, the display of content that is not related to the user can be confirmed. In other words, in the hybrid recorder device described in Patent Document 3, a troublesome display for a user who is not related to the substitute-recorded content is displayed every time the device is activated, and usability in the process of writing from the HD to the optical disk is improved. Has the secondary problem of being bad.

  The present invention has been made in view of the above problems, and its main object is to record content data to be written to a designated medium designated by a user from among a plurality of removable recording media. Provided is a drive device that shortens the writing time of content data from a non-removable recording medium to a designated medium, which occurs when writing to the medium.

  In addition, a content recording / reproducing apparatus that issues a notification that prompts synchronization processing of content to only a user related to the content when there is content that is not synchronized is also provided.

In the drive device according to the present invention, in order to solve the above problems,
A non-removable recording medium;
When a write command for writing content data to a specific area on a designated medium designated by a user is obtained from among a plurality of removable recording media, the content data is written to the non-removable recording medium, A writing means for associating and recording an area on the non-removable recording medium to which the content data is written and a specific area on the designated medium;
When the designated medium is loaded, the content data written on the non-removable recording medium is written to a specific area on the designated medium, and the writing completion notice of the content data is notified to the issuer of the write command. A synchronization means for issuing
It is characterized by having.

  In the drive device according to the present invention, among a plurality of removable recording media, an area on a non-removable recording medium in which content data to be written to a specific area on a designated medium designated by a user is written Recording is performed in association with a specific area on the designated medium, and when the designated medium is loaded, the content data written on the non-removable recording medium is written to the specific area on the designated medium. A content data writing completion notification is issued to the device that has instructed the writing.

  As described above, in the drive device according to the present invention, the content data to be written on the designated medium can be written on a non-detachable recording medium as if it were recorded on the designated medium.

  Therefore, in the drive device according to the present invention, when content data is written from a non-removable recording medium to the designated medium when the designated medium is loaded, the content data is transferred from the non-removable recording medium to the designated medium. Can be written in bits (Bit to Bit). That is, in the drive device according to the present invention, the time required for writing the content from the non-removable recording medium to the designated medium that occurs when the content data to be written to the designated medium is written to the non-removable recording medium. There is an effect that can be shortened.

  In addition, even when the designated medium is not loaded, content data can be written to the designated medium only by supplying a single write instruction to the drive device as the issuer of the write instruction. Play.

  The issuer of the write command can execute various processes by receiving a write completion notification from the drive device according to the present invention.

In the content data synchronization method according to the present invention, in order to solve the above problem,
A method of synchronizing content data in a drive device having a non-detachable recording medium and capable of loading a removable recording medium,
When a write command for writing content data to a specific area on a designated medium designated by a user is obtained from among a plurality of removable recording media, the content data is written to the non-removable recording medium, A writing step of associating and recording an area on the non-removable recording medium to which the content data is written and a specific area on the designated medium;
When the designated medium is loaded, the content data written on the non-removable recording medium is written to a specific area on the designated medium, and the writing completion notice of the content data is notified to the issuer of the write command. A synchronization step that issues
It is characterized by including.

  According to said structure, there exists an effect similar to the drive device based on this invention.

  As described above, in the drive device according to the present invention, among the plurality of removable recording media, it is impossible to attach / detach the content data to be written to a specific area on the designated medium designated by the user. An area on the recording medium is recorded in association with a specific area on the designated medium, and when the designated medium is loaded, content data written on the non-removable recording medium is stored in the specific area on the designated medium. At the same time as writing, a content data write completion notification is issued to the device that has instructed the content data write.

  As a result, the drive device according to the present invention requires writing of content from the non-detachable recording medium to the designated medium, which occurs when content data to be written to the designated medium is written to the non-detachable recording medium. The effect which can shorten time is produced.

  The drive unit 300 has the following new functions in addition to the functions of the conventional optical disc drive apparatus. That is, (1) a registration function for registering a plurality of optical discs designated by the user as My Discs, and (2) when a write command to the optical discs registered as My Discs is given from the back-end unit 200, data is stored in the optical discs. A write function for writing data to a memory provided in the drive unit 300, and (3) instead of reading data from the optical disk when a read command for the my disk is given from the back-end unit 200, A read function for reading data from the memory, and (4) instead of writing to the optical disk registered as My Disk, the data written to the memory is written to the optical disk, and the data recorded in the memory and the optical disk is read Synchronize It has a synchronization function. Then, the back-end unit 200 uses these new functions to record, play back, and edit content. Hereinafter, configuration examples of the back-end unit 200 and the drive unit 300 will be described in order below.

  As shown in FIG. 1, the back-end unit 200 includes a tuner unit 210, an encoder unit 220, a stream processing unit 230, a back-end control unit 240, a decoder unit 260, an image processing unit 270, a buffer unit 250, a storage unit 280, and an interface. Part 290. As shown in FIG. 1, the stream processing unit 230, the back-end control unit 240, the decoder unit 260, the image processing unit 270, the buffer unit 250, the storage unit 280, and the interface unit 290 are connected to each other via a bus line. ing.

  As shown in FIG. 1, the drive unit 300 includes an interface unit 310, a drive control unit 320, a disk drive unit 330, and a storage unit 340. As shown in FIG. 1, the interface unit 310, the drive control unit 320, the disk drive unit 330, and the storage unit 340 are connected to each other via a bus line.

  In this specification and the like, an optical disc associated with each area in the storage unit 340, that is, an optical disc in which the media ID of the storage unit 340 is recorded in the storage unit 340 is referred to as “my disc”.

  Each member with which the back end part 200 and the drive part 300 are provided is demonstrated below.

(Tuner unit 210, encoder unit 220)
The tuner unit 210 is a stream (Transport Stream: TS) in which video data, audio data, and the like are multiplexed from digital broadcast waves (for example, BS digital broadcast, CS digital broadcast, terrestrial digital broadcast) received by the antenna unit. To extract.

  The encoder unit 220 encodes the analog broadcast received by the antenna unit or the video / audio signal input from the outside into the MPEG2-TS format or the MPEG2-PS format.

(Stream processing unit 230, buffer unit 250)
The stream processing unit 230 separates and extracts individual data such as video data and audio data multiplexed in the extracted stream or the encoded stream, and a packet to which the same packet identifier (PID) is assigned. The content data (PES packet) is restored by connecting the payload portions of (TS). Further, content data input via a network by a communication unit (not shown) is also processed in the stream processing unit 230.

  The content data processed by the stream processing unit 230 is temporarily stored in the buffer unit 250. The buffer unit 250 is a memory that temporarily stores content data (video data, audio data, etc.) to be output to the display device or the drive unit 300. The buffer unit 250 generally uses a volatile memory, but may use a nonvolatile memory.

(Backend control unit 240)
The back-end control unit 240 controls overall recording and reproduction of content data in the recorder device 100.

  When the content data restored in the stream processing unit 230 is recorded on the optical disc loaded in the drive unit 300, the back-end control unit 240 performs drive control via the interface unit 290 for a write command for writing to the optical disc. The content data to be written is read from the buffer unit 250 and output to the drive unit 300 via the interface unit 290.

  When playing back the content data recorded on the optical disk loaded in the drive unit 300, the back-end control unit 240 sends a read command for reading the content data from the optical disk to the drive unit 300, and the interface unit 290. To the drive control unit 320. At this time, the content data read from the optical disc is temporarily stored in the buffer unit 250.

  Further, when outputting the content data stored in the buffer unit 250 to the display device, the back-end control unit 240 controls the decoder unit 260 to decode the content data read from the buffer unit 250.

(Decoder unit 260)
In response to an instruction from the back-end control unit 240, the decoder unit 260 converts the content data stored in the buffer unit 250 into a clock (System Time Clock: STC) value generated in the back-end unit 200. Content data to which a matching time stamp (PTS) is assigned is read. Then, the read content data is decoded and output to the image processing unit 270.

(Image processing unit 270)
The image processing unit 270 performs high quality processing such as pixel interpolation and color adjustment to improve the display performance of moving image data such as frame rate conversion, and the moving image data subjected to the high quality processing Is output to a display device (not shown). That is, the image processing unit 270 generates a frame image to be used when actually displayed on the display device from the frame image decoded (decoded) by the decoder unit 260.

  When additional information (for example, subtitles, title list, menu information, icons, etc.) is superimposed on the image displayed on the display device, the image processing unit 270 applies to the moving image data subjected to the quality enhancement processing. To superimpose necessary additional information.

(Storage unit 280)
The storage unit 280 stores a program for operating the back-end control unit 240 and various data referred to by the back-end control unit 240. Examples of data referred to by the back-end control unit 240 include reservation information and title management information. Details of the reservation information and the title management information will be described in detail below, and the description thereof is omitted here. Note that the storage unit 280 is preferably a non-volatile memory whose recorded contents are not erased even when the power is turned off.

(Interface units 290 and 310)
The interface unit 290 outputs the input data to the drive unit 300 via the interface unit 310. Examples of the interface unit 290 include SATA (Serial AT attachment). Note that ATA (AT attachment) is not limited to SATA in which the transfer method is serial ATA, but PATA (Parallel AT attachment) in which the transfer method is parallel ATA may be used.

  The interface unit 310 outputs the input data to the backend unit 200 via the interface unit 290. Similarly to the interface unit 290, the interface unit 310 may be SATA or the like, but the interface unit 290 and the interface unit 310 are preferably interfaces of the same standard.

  In the present embodiment, the case where the interface units 290 and 310 are SATA will be described as an example.

(Drive control unit 320)
The drive control unit 320 controls reading of data from the optical disc loaded in the disc drive unit 330 and writing of data to the optical disc, reading of data from the storage unit 340, and data to the storage unit 340. Control writing.

  In the drive control unit 320, a command (a data read command from the optical disc or a data write command to the optical disc) input from the back end control unit 240 that is input via the interface unit 310, a data read command from the storage unit 340, Alternatively, it is replaced with a data write command to the storage unit 340. However, when the command from the back end control unit 240 is a read command for data not stored in the storage unit 340, the drive control unit 320 does not replace the command from the back end control unit 240 and loads Read data from the optical disc.

  When the interface units 290 and 310 are ATA interfaces, a write command and a read command from the back-end control unit 240 are ATA commands.

  Further, in this embodiment, in order to realize a data write command for a predetermined area, information (disk designation information) indicating which area (my disk to be described later) in the storage unit 340 is to write data. It is preferable to include the command and output it to the drive control unit 320. Of course, in addition to using a command including disk designation information, a command indicating the disk designation information is output in advance to designate a recording target area (my disk) in the storage unit 340, and then a write command and write target data are represented. The command may be output to the drive control unit 320. In any case, the write command includes disk designation information and an address (disk area designation information) for designating an area in which data is to be written. Note that the data to be written is output from the back end unit 200 to the drive unit 300 together with the write command.

  This is not limited to the write command, and the same applies to the read command.

(Disc drive unit 330)
The disk drive unit 330 operates based on an instruction from the drive control unit 320, and reads data from the loaded optical disk or writes data to the optical disk.

  The disk drive unit 330 includes an optical pickup unit for reading data from a loaded optical disk and writing data to the optical disk.

(Storage unit 340)
The storage unit 340 is a data memory that stores data such as content data to be recorded on the optical disc in the recorder device 100. The recording of content data in the storage unit 340 will be described in detail below, and the description thereof is omitted here.

  The storage unit 340 is not particularly limited as long as the data access speed is higher than that of the optical disc, but is preferably a nonvolatile memory in which recorded contents are not erased even when the power is turned off. More specifically, it is preferable to use a flash memory.

(Processing operation of recorder device 100)
Next, playback operation, recording operation, dubbing operation, and the like of the recorder device 100 will be described. Prior to the description of each operation in the recorder device 100, the presetting in the recorder device 100 is illustrated in FIG. This will be described with reference to FIGS. 2B, 3A, and 3B. The presetting in the recorder apparatus 100 can be roughly divided into two processes: an initialization process for the storage unit 340 and an optical disk registration process for the storage unit 340.

<Initialization Processing of Storage Unit 340>
The initialization process of the storage unit 340 will be described with reference to FIG. 2A and FIG. 2A and 2B are diagrams showing an initialization process of the storage unit 340, and FIG. 2A is a diagram showing an example of display on the display device when the storage unit 340 is initialized. (B) is a diagram schematically showing the storage unit 340 after the initialization process.

  The initialization process of the storage unit 340 is a process of virtually dividing the storage area in the storage unit 340 into as many partitions as the user desires. Note that the initialization processing of the storage unit 340 is executed only when the storage area is not virtually divided in the storage unit 340, and therefore the initialization processing in the storage unit 340 has already been performed. The initialization process is not executed for.

  The initialization process is executed by receiving an initialization process execution instruction from the user via the operation input unit. That is, when the back-end control unit 240 receives an initialization processing execution instruction from the user, the back-end control unit 240 virtually determines the storage area of the storage unit 340 to the number designated by the user with respect to the drive control unit 320. Instruct to split. In response to the instruction from the back-end control unit 240, the drive control unit 320 virtually divides the storage unit 340 into a specified number of areas (partitions). The number of areas divided in the storage unit 340 matches the number of My Disks that can be registered. At this time, it is preferable to display an image as shown in FIG.

  Note that the number of regions virtually divided in the storage unit 340 may be a number that is explicitly instructed by the user, such as “n (sheets)”, or the recording desired by the user. The number may be set according to the image quality.

  FIG. 2B shows the storage unit 340 after the initialization process. As shown in FIG. 2B, the storage unit 340 is virtually divided into n regions (region 1 to region n) desired by the user. In addition to the areas 1 to n, the storage unit 340 is provided with a management area in which management information for managing the areas 1 to n is recorded.

  As shown in FIG. 2B, the management area can be divided into a my disk management area for managing the areas 1 to n and a memory management area for managing the my disk management area.

  In the my disk management area, management information for managing the areas 1 to n is recorded. In FIG. 2B, for convenience, an area in which management information for managing area 1 is recorded is referred to as “entry 1”, and an area in which management information for managing areas 2 to n is similarly recorded. Called entries 2-n.

  In entry 1 managing area 1, an entry number, an allocation flag, media ID information, allocation area information, media key information, and map information are recorded. Each of these pieces of information will be described below.

  “Entry number” is information indicating which area is to be managed. For example, since entry 1 is management information for managing area 1, information indicating “1” is recorded as the entry number.

  The “assignment flag” is a flag indicating whether or not the area is associated with MyDisk. In the state immediately after the initialization process, since my disk is not associated, information indicating that the assignment is not performed (here, “0”) is recorded.

  “Media ID” is information indicating the media ID of the optical disc. In the initialization process stage, the media ID information is not recorded. The recording of the media ID information will be described later in the optical disk registration process.

  The “allocation area information” is information indicating a recording area of the storage unit 340 that can be used as each area. As specific examples of the allocation area information, for example, the start address and the end address of each area can be cited. Further, the recording capacity of each area may be recorded instead of the end address.

  “Media key information” is key information for executing encryption used for copyright protection when data is recorded on an optical disc. Examples of the media key information include MKB (Media Key Block).

  “Map information” includes, for each content recorded on the optical disc, a virtual address that is an address indicating an area of the optical disc in which the content is recorded, and an address that indicates an area on the storage unit 340 in which the content is recorded. This is information indicating the association with the physical address. The details of the map table recorded as the map information will be described in detail below, and the description is omitted here.

  Further, as shown in FIG. 2B, “entry number information” and “allocation area information” are recorded in the memory management area. “Number of entries” is information indicating the number of regions virtually divided in the storage unit 340. “Allocation area information” is information indicating an area used as a My Disk management area in the storage unit 340.

  Note that a surplus area generated when the storage unit 340 is virtually divided into the areas 1 to n may be used as a spare area.

<Optical disk registration process>
Next, an optical disk registration process with respect to the storage unit 340 will be described with reference to FIGS. 3A and 3B. FIGS. 3A and 3B are diagrams showing an optical disk registration process, and FIG. 3A is a diagram showing an example of display on the display device during the optical disk registration process. b) is a diagram schematically showing the storage unit 340 after the registration processing of the optical disc.

  The optical disk registration process is a process of recording the media ID of the optical disk for the entry managing each area virtually divided in the storage unit 340.

  When the optical disk is loaded in the drive unit 300, the drive control unit 320 instructs the disk drive unit 330 to read the media ID of the optical disk from the loaded optical disk. When the disk drive unit 330 reads the media ID from the optical disk, the drive control unit 320 determines whether the media ID read in the storage unit 340 is a media ID already recorded in an entry in the my disk management area. .

  When the read media ID is not recorded in any of the entries in the my disk management area, the drive control unit 320 indicates that the allocation flag is not allocated to the optical disk among the entries in the my disk management area. The read media ID is recorded in the entry “0”. Thereby, the media ID information is recorded in the entry. Note that the allocation flag in the entry in which the media ID information is recorded is changed to “1” indicating that the allocation is performed at the time when the media ID information is recorded. Also, information unique to the optical disc such as media key information is also recorded for the entry that recorded the media ID information at this time.

  In the above-described optical disk registration process, the case where the read media ID is automatically recorded in the entry whose allocation flag is “0” has been described. It is preferable to ask the user whether or not to record the ID in the entry. In this case, the drive control unit 320 records the media ID in response to an instruction from the user that the recorder device 100 records the media ID in the entry.

  In addition, when there are a plurality of entries having the allocation flag “0”, the user may be able to select which entry the media ID is recorded on. In this case, the drive control unit 320 records the media ID for the entry specified by the user.

  When recording the media ID in the entry, it is preferable to display an image as shown in FIG. 3A on the display device.

  FIG. 3B shows the state of the storage unit 340 after registration of the optical disc when the optical disc having the media ID “aaa” is recorded in the entry 1.

  When the media ID of the optical disk is recorded in entry 1, the optical disk is associated with area 1 managed by entry 1, as shown in FIG.

  In this specification and the like, an optical disc associated with each area in the storage unit 340, that is, an optical disc in which the media ID of the storage unit 340 is recorded in the storage unit 340 is referred to as “my disc”. In addition, in order to identify the My Disk, here, the My Disk associated with the area 1 is referred to as “Disk 1”. Similarly, the my disk associated with the areas 2 to n will be referred to as “disks 2 to n”.

<Reserved video recording operation>
The content recording operation, content reproduction operation, content editing operation, and content copying operation in the recorder apparatus 100 that has been previously set will be described below.

  The content recording operation in the recorder device 100 will be described below with reference to FIGS. 4A to 4C to 13A to 13C. Here, the reservation recording process will be described as an example of the content recording operation.

  The reserved recording process in the recorder apparatus 100 can be roughly divided into a reservation registration process and a recording process. The recording process can be further divided into two processes: a recording process in a state where a my disk is loaded and a recording process in a state where a my disk is not loaded. Each of these processes in the scheduled recording process will be described below.

(Reservation registration process)
First, reservation registration processing in the recorder apparatus 100 will be described below with reference to FIGS. 4A to 4C. 4A to 4C are diagrams showing reservation registration processing in the recorder apparatus 100, and FIG. 4A is a diagram schematically showing the state of the storage unit 280 after the reservation registration processing. (B) is a diagram schematically showing the state of the storage unit 340 and MyDisk 1 after the reservation registration process, and (c) is a diagram showing an example of display on the display device during the reservation registration process. It is.

  The reservation registration process is a process for registering reservation information in the storage unit 280 and the optical disc. The reservation registration process will be described by taking as an example a case where the disk 1 associated with the area 1 of the storage unit 340 is loaded.

  When the user inputs reservation information via the operation input unit, the back-end control unit 240 records the input reservation information in the reservation information management area of the storage unit 280. At this time, the reservation information recorded in the reservation information management area of the storage unit 280 includes “recording channel”, “recording date” and “recording time” as well as “recording time” as shown in FIG. Information on “Target My Disk” is included. Hereinafter, the recording target My Disc information will be described by taking the media ID of the loaded My Disc as an example, but other information may be used as long as the information can identify the My Disc. Each piece of information included in the reservation information may be input by the user, or may be set based on program information representing a program selected by the user in the electronic program guide.

  The back-end control unit 240 records the reservation information in the storage unit 280 and instructs the drive control unit 320 to write the reservation information to the disk 1 loaded in the drive unit 300. In response to the instruction from the back-end control unit 240, the drive control unit 320 instructs the disk drive unit 330 to record the reservation information set by the user on the disk 1. In response to an instruction from the drive control unit 320, the disk drive unit 330 records the reservation information set by the user in a predetermined area (reservation information management area) of the disk 1 ((b) of FIG. 4). At this time, since the media ID is already recorded on the disc 1, it is not necessary to record the media ID.

  It should be noted that the user may be able to select the recording target my disk when setting the reservation information. In this case, if the recording target my disk selected by the user is not loaded in the drive unit 300, the user is warned to load the target my disk in the drive unit 300 at the time of registration of the reservation information. It is preferable to do so.

  FIG. 4C shows an example of an image displayed on the display device at the time of reservation registration when the disc 1 associated with the area 1 of the storage unit 340 is loaded.

(Recording process when My Disk is loaded)
Next, with respect to the recording process in the case where a My Disk having the media ID included in the reservation information recorded in the reservation information management area of the storage unit 280 is loaded in the drive unit 300, (a) in FIG. This will be described below with reference to FIG. FIGS. 5A and 5B are diagrams showing the recording process in a state where the My Disk is loaded. FIG. 5A shows the state of the storage unit 340 and the My Disk 1 after the recording process. (B) is a diagram schematically showing the state of the storage unit 280 after the recording process.

  When the recording of the content 1 is completed, as shown in FIG. 5B, the back-end control unit 240 deletes the reservation information indicating the reservation recording of the content 1 from the reservation information management area in the storage unit 280. When the recording of the content 1 on the disc 1 is completed, the drive control unit 320 instructs the disc drive unit 330 to erase the reservation information recorded in the reservation information management area of the disc 1.

  Next, the state of the storage unit 340 and the storage unit 280 when the content 1 is recorded in the area 1 of the storage unit 340 and the disc 1 will be described below with reference to FIGS. 6A to 6C. To do. 6A to 6C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 1 is recorded. FIG. 6A is a diagram illustrating the content of the area 1 in the storage unit 340. It is a figure which shows the correspondence of the recording state of the disc 1 corresponding to a recording state, (b) is a figure which shows the map table at the time of recording the content 1, (c) is a title at the time of recording the content 1 It is a figure which shows a management table.

  Here, generally, the data capacities of the area 1 of the storage unit 340 and the disk 1 are different. For this reason, in the area 1, a virtual address that matches the address in the disk 1 (disk area designation information) is assigned separately from the physical address. By reading or writing data using this virtual address, the content stored in the storage unit 340 is recorded on the disc 1 loaded in the drive unit 300 in the back-end unit 200. Can be handled. In this specification and the like, a storage area represented by using a virtual address set in each area of the storage unit 340 is referred to as a “virtual disk image”.

  FIG. 6A shows a virtual disk image in the area 1 of the storage unit 340. As shown in FIG. 6A, in the area 1 of the storage unit 340, when the content 1 (data capacity: XGB) is recorded with the physical address (storage unit area designation information) “0x000” as the head address, On the virtual disk image, content 1 is recorded with the virtual address “0x050” as the head address. That is, when the content 1 is written to the disc 1, the drive control unit 320 instructs the disc drive unit 330 to write the content 1 from the sector representing the address “0x050” of the disc 1. As a result, content recording from the area 1 to the disc 1 can be easily executed.

  Next, a map table for realizing the association between the physical address and the virtual address shown in FIG. 6A will be described with reference to FIG.

  The map table is recorded as map information in the My Disk management area of the storage unit 340. As shown in FIG. 6B, the map table records a virtual disk map representing a map in the virtual disk image and a memory map representing a map in the area 1 of the storage unit 340 in association with each content. ing. Further, a synchronization flag indicating whether or not the content is recorded on the My Disc is recorded in association with the content.

  In this specification and the like, a state where content recorded in a certain area of the storage unit 340 is recorded on a My Disk associated with the certain area is referred to as “synchronization”. Similarly, a process in which content recorded in a certain area of the storage unit 340 is recorded on a My Disk associated with the certain area is referred to as “synchronization process”.

  In the map table, content 1 is recorded in area 1 and the content is updated. FIG. 6B shows a map table when the area 1 of the storage unit 340 is in the state shown in FIG. As shown in FIG. 6B, in the map table, “0x050” is set as the head address in the virtual disk map in content 1, XGB is set as the data size, and “0x000” is set as the head address in the memory map. Is set, and XGB is set as the data size. Further, the writing from the area 1 to the disc 1 is completed, and the synchronization flag in the map table becomes “1” indicating that the content is recorded on the My Disc.

  By referring to such a map table, the drive control unit 320 that has received a write command to the disk 1 from the back-end control unit 240 sends the write command to the disk 1 received from the back-end control unit 240 to the area 1. Can be changed to a write command. Similarly, a read command from the disk 1 can be changed to a read command from the area 1 by referring to the map table.

  The entry parameter in FIG. 6B is an area for recording an entry number, media ID information, allocation area information, and the like, and the entry data area is for recording media key information and track information in area 1. It is an area to do.

  Further, the content 1 is recorded in the area 1, and the title management table recorded as the title management information in the title management area of the disc 1 in the storage unit 280 is updated. The title management table recorded in the content management area in which information related to the content 1 is set will be described with reference to FIG. Note that as many title management areas as the number of areas virtually divided in the storage unit 340 are provided in the storage unit 280.

  In the title management table, as shown in FIG. 6C, for the title name indicating each content, the required time for content reproduction, the image quality of the content reproduction, and the number of remaining dubbing times (maximum 10). In addition, information indicating the synchronization state is recorded in association with each other. Note that a title indicating the content 1 is described as a title 1. Similarly, titles indicating content 2 to content n are written as title 2 to title n.

  An example of the title management table when the map table shown in FIG. 6B is set is shown in FIG. At this time, since the content 1 is recorded on the disc 1, the remaining dubbing count in the title 1 is subtracted once from the remaining 10 times to “9” times.

  In the above description, a method similar to the dubbing frequency control in “dubbing 10”, which is a copy control method for copyright protection, which has been started in digital television broadcasting in Japan since July 2008, is taken as an example. Although the description has been given, of course, the present invention is not limited to this. For example, if there is another feasible and operable copy control, the dubbing number control according to another copy control method may be performed. The same applies to the dubbing frequency control in the following description.

(Recording process when My Disk is not loaded)
Next, with respect to the recording process when the My Disk having the media ID included in the reservation information recorded in the reservation information management area of the storage unit 280 is not loaded in the drive unit 300, (a) in FIG. This will be described below with reference to FIG. FIGS. 7A and 7B are diagrams showing a recording process in a state where the my disk is not loaded in the recorder apparatus 100, and FIG. 7A is a state of the storage unit 340 after the recording process. (B) is a diagram schematically showing the state of the storage unit 280 after the recording process.

  In the recorder apparatus 100, when the recording of the content (content 2) recorded by the reservation information recorded in the reservation information management area of the storage unit 280 is started, the disc 1 is not loaded in the drive unit 300. Even so, the back-end control unit 240 instructs the drive control unit 320 to record the content 2 on the disc 1. The drive control unit 320 that has received an instruction from the back-end control unit 240 sends a write command to the disk 1 from the back-end control unit 240 in the storage unit 340 because the disk 1 is not loaded in the disk drive unit 330. The content 2 is recorded in the area 1 after being converted into a write command to 1. At this time, since the disc 1 is not loaded in the drive unit 300, the process of recording the content 2 on the disc 1 is not executed.

  When the recording of the content 2 is completed, as shown in FIG. 7B, the back-end control unit 240 deletes the reservation information indicating the reservation recording of the content 2 from the reservation information management area in the storage unit 280.

  Next, the state of the storage unit 340 and the storage unit 280 when the content 2 is recorded in the area 1 of the storage unit 340 will be described below with reference to FIGS. 8A to 8C. FIG. 8A to FIG. 8C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 2 is recorded, and FIG. 8A is a view of the content in the area 1 of the storage unit 340. It is a figure which shows the correspondence of the recording state of the disc 1 corresponding to a recording state, (b) is a figure which shows the map table at the time of recording the content 2, (c) is a title at the time of recording the content 2 It is a figure which shows a management table.

  As shown in FIG. 8A, since content 1 (data capacity: XGB) is recorded with the physical address “0x000” in the area 1 of the storage unit 340 as the head address, content 2 (data capacity: XGB) is recorded. Is recorded following the content 1 with the physical address “0x200” in the area 1 of the storage unit 340 as the head address. At this time, the content 2 is recorded following the content 1 with the virtual address “0x250” as the head address even on the virtual disk image. Since the disc 1 is not loaded in the drive unit 300, the content 2 is naturally not recorded on the disc 1.

  The content 2 is recorded in the area 1, and the map table recorded in the map information in the entry 1 of the storage unit 340 is also updated. FIG. 8B shows a map table in which the area 1 of the storage unit 340 is in the state shown in FIG. As shown in FIG. 8B, in addition to the map table shown in FIG. 6B, “0x250” is set as the start address in the virtual disk map in content 2, and XGB is set as the data size. “0x200” is set as the head address in the memory map, and XGB is set as the data size. At this time, since writing from the area 1 to the disc 1 is not executed, the synchronization flag of the content 2 in the map table is “0” indicating that the content is not recorded on the My Disc.

  FIG. 8C shows an example of the title management table when the map table shown in FIG. 8B is set. As shown in FIG. 8C, in the title management table, in addition to the title management information of the title 1 indicating the content 1 shown in FIG. 6C, the title management information of the title 2 indicating the content 2 is stored. Added. Since the title 2 is not recorded on the disc 1 at this time, the remaining dubbing count in the title 2 remains “10”, and the synchronization state is information indicating unsynchronization.

(Content synchronization processing)
Next, with respect to the synchronization processing for recording the content recorded in the storage unit 340 but not recorded on the My Disc on the My Disc, FIGS. 9 to 11 (a) to FIG. This will be described below with reference to (c).

  When the disc 1 is loaded in the drive unit 300, the drive control unit 320 refers to the map table of the entry 1 and determines whether there is content whose synchronization flag is “0”. For example, when there is content 2 whose synchronization flag is “0”, the drive control unit 320 records the content 2 recorded in the area 1 of the storage unit 340 on the disc 1 so as to record (write out) the content 2 on the disc 1. The unit 330 is instructed. The disc drive unit 330 writes the content 2 recorded in the area 1 of the storage unit 340 to the disc 1 in response to an instruction from the drive control unit 320. As a result, the contents 1 and 2 recorded in the area 1 of the storage unit 340 are both recorded on the disc 1 (FIG. 9). That is, the content 2 is in a synchronized state.

  The timing of performing such content synchronization processing may be immediately after the disc 1 is loaded in the drive unit 300, or may be performed at any time during the period from loading to removal. For example, the synchronization process may be performed at a timing at which the recorder device 100 or at least an idle state in which the drive unit 300 is not used. In addition, when it is known that the recorder device 100 or at least the drive unit 300 is not in an idle state for the time being, the content synchronization processing is not performed at this time, and the disc 1 is loaded into the drive unit 300 next time. Sometimes it can be done. For example, when the disk 1 is loaded in the drive unit 300, the recorder device 100, or at least the drive unit 300, is necessary for performing the synchronization process such as when the reserved recording starts immediately in the standby state for the reserved recording. If it is found that a sufficient amount of time cannot be secured, the content synchronization process is not performed at least immediately, or the synchronization process is not performed while the worst recorder apparatus 100 is activated this time, and the next recorder apparatus It may be performed when 100 is activated and the disk 1 is loaded.

  When the writing of the content 2 to the disc 1 is completed, the drive control unit 320 notifies the back-end unit 200 that the synchronization process of the content 2 has been completed (that is, notifies the back-end unit 200 of the completion of writing). Issue). Upon receiving this notification, the back end control unit 240 updates the title management table recorded in the title management area of the disc 1 in the storage unit 280.

  Further, when the writing of the content 2 to the disc 1 is completed, the drive control unit 320 instructs the disc drive unit 330 to erase the reservation information for pre-recording the content 2 recorded on the disc 1. Upon receiving the instruction, the disk drive unit 330 deletes reservation information for reservation recording of the content 2 recorded in the reservation information management area of the disk 1 (FIG. 9). FIG. 9 is a diagram showing the state of the storage unit 340 and the disc 1 after the content synchronization processing.

  Next, referring to FIGS. 10A to 10C for the state of the storage unit 340 and the storage unit 280 when the content 2 recorded in the area 1 of the storage unit 340 is written to the disc 1. However, it will be described below. 10A to 10C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 2 is synchronously processed, and FIG. 10A is the content in the region 1 of the storage unit 340. FIG. 5B is a diagram illustrating a map table when the content 2 is synchronously processed, and FIG. 5C is a diagram illustrating the synchronous processing of the content 2. It is a figure which shows the title management table at the time of making it do.

  As shown in FIG. 10A, in the virtual disk image, the content 2 is recorded with the virtual address “0x250” as the head address. At this time, since the content 1 can be recorded on the disc 1 with “0x250” as the head address, the content 2 is recorded on the disc 1 with the address “0x250” of the disc 1 as the head address.

  When the synchronization processing of the content 2 is completed, as shown in FIG. 10B, the synchronization flag of the map table recorded in the map information of the entry 1 indicates that the content is recorded on the My Disk. 1 ". Further, as shown in FIG. 10C, in the title management table of the disc 1 recorded in the storage unit 280, the remaining dubbing count in the title 2 is decremented by 1 to “9” times, and the synchronization state Is changed to information indicating synchronization.

  Next, with respect to the synchronization processing of the content 2 when the content (content 3) having “0x250” as the head address is already recorded on the disc 1, refer to FIG. 11 (a) to FIG. 11 (d). Will be described below.

  11A to 11D are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 2 is synchronized, and FIG. 11A is the top of the content 2 in the virtual disk image. FIG. 7 is a diagram showing a state in which content 3 having an address as a head address is recorded on the disc 1, and (b) is a diagram showing a state in which the virtual disc image is changed so that the content 2 follows the content 3. (c) is a diagram showing a map table when the content 2 is synchronously processed, and (d) is a diagram showing a title management table when the content 2 is synchronously processed.

  As shown in FIG. 11A, when content 3 having a head address “0x250”, which is the head address of content 2 in the virtual disk image, is already recorded on the disk 1, the address “0x250” of the disk 1 is recorded. The content 2 cannot be recorded on the disc 1 with the leading address.

  At this time, the drive control unit 320 can record the content 2 on the disc 1 by changing the virtual disc image in the storage unit 340. That is, the drive control unit 320 sets the content 3 recorded with the address “0x250” as the head address in the disk 1 so that the virtual address “0x250” is recorded as the head address in the virtual disk image. The content 2 is set to follow the content 3 so that the virtual address “0x400” is recorded as the head address. That is, the drive control unit 320 changes the virtual disk image in the area 1. Thus, in the changed virtual disk image, the start address of the content 2 is “0x400”, so that the content 2 can be recorded on the disk 1 with “0x400” as the start address.

  At this time, the map table of region 1 is also changed as shown in FIG. That is, the top address of the content 2 in the virtual disc map is “0x400”, which is “1” indicating that the content is recorded on the My Disc. Also, in the virtual disk map, the content 3 having a head address “0x250” and a content capacity of YGB is registered. Since the content 3 is content that is not recorded in the area 1, the start address is not recorded in the memory map, and the synchronization flag is not recorded.

  Similarly, as shown in FIG. 11D, in the title management table of the disc 1 in the storage unit 280, the synchronization state associated with the title 2 is changed to information indicating synchronization, and the title 3 indicating the content 3 is displayed. Information (reproduction time and reproduction image quality) associated with is registered. At this time, the content 3 is content recorded only on the disc 1 and cannot be dubbed, so the remaining number of times of dubbing in the title 3 is not displayed.

(Delete contents recorded in area 1)
When the free space of the area 1 in the storage unit 340 is reduced, the content recorded in the area 1 may be deleted. The deletion of the content recorded in the area 1 may be executed according to a user instruction, or may be automatically executed when the free space in the area 1 becomes a predetermined value or less. good.

  FIG. 12 is a diagram illustrating a state of the storage unit 340 and the disk 1 when the content 4 is newly recorded after the content 1 and the content 2 recorded in the area 1 are deleted. In FIG. 12, the content 4 is also recorded on the disc 1 for recording in a state where the My Disc is loaded.

  The states shown in FIG. 12, that is, the states of the storage unit 340 and the storage unit 280 when the content 4 is recorded in the region 1 after deleting the content 1 and the content 2 from the region 1, are shown in FIG. This will be described below with reference to c). FIG. 13A to FIG. 13C are diagrams showing the states of the storage unit 340 and the storage unit 280 when the content 4 is recorded. FIG. 13A is a diagram illustrating the content in the region 1 of the storage unit 340. It is a figure which shows the correspondence of the recording state of the disk 1 corresponding to a recording state, (b) is a figure which shows the map table at the time of recording the content 4, (c) is a title at the time of recording the content 4 It is a figure which shows a management table.

  When the content 1 and the content 2 are deleted from the area 1, the drive control unit 320 deletes information regarding the content 1 and the content 2 from the memory map in the map table recorded in the entry 1 of the storage unit 340. The drive control unit 320 also deletes the synchronization flag associated with the contents 1 and 2. However, as shown in FIG. 13A, the contents 1 and 2 remain on the virtual disk image without being erased. That is, as shown in FIG. 13B, even if the contents 1 and 2 are deleted from the area 1, the information on the contents 1 and 2 is not deleted from the virtual disk map in the map table. It will be.

  Therefore, the drive control unit 320 instructs the disk drive unit 330 to record the content 4 so as to follow the content 2 already recorded in the virtual disk image, that is, the virtual address “0x650”.

  Further, as shown in FIG. 13C, the title management table in the storage unit 280 is also changed as the contents 1 and 2 are deleted from the area 1. When the content 1 and the content 2 recorded in the area 1 are deleted, the back-end control unit 240 deletes information indicating the remaining number of dubbing times and the synchronization state of the content 1 and the content 2 in the title management table in the storage unit 280. To do. Next, when the content 4 is recorded in the area 1, the back-end control unit 240 registers information related to the title (title 4) indicating the content 4 in the title management table.

<Content playback operation>
Next, the content reproduction operation in the recorder apparatus 100 will be described below with reference to FIGS.

  The content reproduction process is a process executed in response to a content reproduction instruction from the user via the operation input unit. For example, when the user selects playback of a title displayed on the display device, the back-end control unit 240 executes the content playback process on the assumption that the playback instruction of the content represented by the selected title has been received. Note that the title displayed on the display device is a title recognized by the back-end unit 200. The title recognized in the back-end unit 200 can be rephrased as the title registered in the title management table recorded in the title management area of the storage unit 280.

  Note that the content playback operation in the recorder apparatus 100 can be broadly divided into playback processing when a My Disc is loaded and playback processing when a My Disc is not loaded. Each reproduction process will be described below.

(Playback process when My Disc is loaded)
Reproduction processing when a My Disk is loaded will be described below with reference to FIGS. FIG. 14 is a diagram illustrating a state of the storage unit 340 and the storage unit 280 when the disc 1 on which the contents 1 to 3 are recorded is loaded. FIG. 15 is a diagram schematically showing a medium from which content is read during reproduction when a My Disc is loaded.

  As shown in FIG. 14, the disc 1 on which the contents 1 to 3 are recorded is loaded in the drive unit 300, and the contents 1 and 2 are recorded in the area 1 of the storage unit 340. Therefore, information on titles 1 to 3 is recorded in the title management table in the title management area of the storage unit 280. That is, the back end unit 200 can recognize the contents 1 to 3 represented by the titles 1 to 3. In FIG. 14, the details of the title management table are omitted.

  As a playback process when the My Disc is loaded, the playback process when the content 1 recorded in both the disc 1 and the area 1 is played back will be described first and then recorded on the disc 1. However, a reproduction process in the case of reproducing the content 3 not recorded in the area 1 will be described.

  The back-end control unit 240 outputs a command for reading the content 1 recorded on the disc 1 to the drive unit 300 via the interface unit 290. The drive control unit 320 that has received a command from the back-end control unit 240 refers to the map table and determines whether or not the content 1 recorded on the disc 1 is recorded in the area 1. At this time, since the content 1 is the content recorded in the area 1, the drive control unit 320 reads the read command from the disc 1 received from the back-end control unit 240 from the area 1 with reference to the map table. Is converted into a read instruction. That is, the drive control unit 320 converts the address of the disk 1 into the physical address of the area 1 with reference to the map table.

  The drive control unit 320 that has read the content 1 from the area 1 outputs the read content 1 to the back-end unit 200 via the interface unit 310.

  As described above, when the content to be read is recorded on both the My Disc and the storage unit 340, the content is read from the storage unit 340 as shown in FIG.

  Similarly, when playing back the content 3 recorded on the disc 1 but not recorded in the area 1, the back-end control unit 240 sends an instruction for reading the content 3 recorded on the disc 1 to the interface unit 290. To the drive unit 300. The drive control unit 320 that has received a command from the back-end control unit 240 refers to the map table and determines whether or not the content 3 recorded on the disc 1 is recorded in the area 1. At this time, since the content 3 is content not recorded in the area 1, the drive control unit 320 sends the content 3 to the disc drive unit 330 in accordance with the read command from the disc 1 received from the back-end control unit 240. Is to be read.

  When the content 3 is read from the disc 1, the drive control unit 320 outputs the read content 3 to the back end unit 200 via the interface unit 310.

  As described above, when the content to be read is not recorded in the storage unit 340, the content is read from My Disk as shown in FIG.

(Playback process when My Disk is not loaded)
Next, the reproduction process in the case where no my disk is loaded will be described below with reference to FIGS. FIG. 16 is a diagram illustrating a state of the storage unit 340 and the storage unit 280 when no optical disk is loaded in the drive unit 300. FIG. 17 is a diagram schematically showing a medium from which content is read out during reproduction when no My Disc is loaded.

  As shown in FIG. 16, content 1 and content 2 are recorded in area 1 of storage unit 340. However, unlike the case of FIG. 14, the disc 1 on which the contents 1 to 3 are recorded is not loaded in the drive unit 300. Note that information on titles 1 to 3 is recorded in the title management table in the title management area of the storage unit 280. That is, the back end unit 200 can recognize the contents 1 to 3 represented by the titles 1 to 3. In FIG. 16, as in FIG. 14, details of the title management table are omitted.

  In the case of the state shown in FIG. 16, among the contents 1 to 3 represented by the titles 1 to 3 recognized in the back end unit 200, the contents 1 and 2 recorded in the area 1 of the storage unit 340. Can be reproduced, but the content 3 recorded only on the disc 1 cannot be reproduced.

  That is, as shown in FIG. 17, when the content to be read is recorded on both the My Disc and the storage unit 340, the content is stored by the same processing as when the My Disc is loaded. Read from the unit 340. However, content recorded only on the disc 1 cannot be read.

  The content 1 reading process shown in FIG. 17 is the same as the content 1 reading process in the case where the My Disc is loaded, and thus the description thereof is omitted here.

<Content editing operation>
Next, the content editing operation in the recorder apparatus 100 will be described below with reference to FIGS. 18, 19A and 9B.

  The content editing process is a process executed in response to a content editing instruction from the user via the operation input unit. For example, when the user selects to edit the title displayed on the display device, the back-end control unit 240 edits the content selected by the user on the assumption that the back-end control unit 240 has received an instruction to edit the content represented by the selected title. Execute the process. Note that the title displayed on the display device is a title recognized by the back-end unit 200. The title recognized in the back-end unit 200 can be rephrased as the title registered in the title management table recorded in the title management area of the storage unit 280. That is, the title registered in the title management table can be edited regardless of the recording medium.

  Similar to the content reproduction process, the content editing operation in the recorder apparatus 100 can be broadly divided into an editing process when a my disk is loaded and an editing process when a my disk is not loaded. Each editing process will be described below.

  The content editing process is a process of changing at least a part of the data recorded in the My Disc or the storage unit 340. Specifically, the content is deleted from the scene (partial change of the content data). ), Processing including deletion of content and addition of chapter in content. Note that, here, scene erasure in the content will be described as an example, but other processing can be similarly performed.

(Editing process when My Disc is loaded)
The editing process when a My Disk is loaded will be described below with reference to FIGS. FIG. 18 is a diagram schematically showing a medium on which content is edited when a My Disc is loaded.

  As shown in FIG. 14, the disc 1 on which the contents 1 to 3 are recorded is loaded in the drive unit 300, and the contents 1 and 2 are recorded in the area 1 of the storage unit 340. The title management table in the title management area of the storage unit 280 stores information on the titles 1 to 3, and the back end unit 200 recognizes the contents 1 to 3 represented by the titles 1 to 3. Can do. In FIG. 14, the details of the title management table are omitted.

  As a reproduction process in the case where the My Disc is loaded, the process in the case of editing the content 1 recorded in both the disc 1 and the area 1 will be described first, and then recorded on the disc 1. A process in the case of editing the content 3 not recorded in the area 1 will be described.

  The back-end control unit 240 outputs an instruction to change the data of the content 1 recorded on the disc 1 to the drive unit 300 via the interface unit 290. The drive control unit 320 that has received a command from the back-end control unit 240 refers to the map table and determines whether or not the content 1 recorded on the disc 1 is recorded in the area 1. At this time, since the content 1 is the content recorded in the area 1, the drive control unit 320 refers to the map table for an instruction to change data in the disc 1 received from the back-end control unit 240. 1 is converted into an instruction to change data. That is, since the drive control unit 320 refers to the map table and converts the address of the disc 1 into the physical address of the area 1, the data of the content 1 recorded in the area 1 is actually changed. It will be.

  As described above, when the content whose data is to be changed is recorded in both the My Disc and the storage unit 340, the data of the content recorded in the storage unit 340 is changed as shown in FIG. It will be.

  However, since the content 1 recorded in the disc 1 and the content 1 recorded in the area 1 remain different (asynchronous state), the drive control unit 320 records in the area 1. The data change made for the content 1 is also reflected on the content 1 recorded on the disc 1. The change reflected on the content 1 recorded on the disc 1 may be reflected at any time until the disc 1 is removed from the drive unit 300.

  Similarly, when the data of the content 3 recorded in the disc 1 but not recorded in the area 1 is changed, the back end control unit 240 similarly changes the data of the content 3 recorded in the disc 1. Is output to the drive unit 300 via the interface unit 290. The drive control unit 320 that has received a command from the back-end control unit 240 refers to the map table and determines whether or not the content 3 recorded on the disc 1 is recorded in the area 1. At this time, since the content 3 is content not recorded in the area 1, the drive control unit 320 follows the instruction to change the data of the content 3 recorded on the disc 1 received from the back-end control unit 240. Instructs the disk drive unit 330 to change the data of the content 3.

(Editing process when My Disk is not loaded)
Next, content editing processing when no My Disc is loaded will be described below with reference to FIGS. 16, 19A and 19B. FIGS. 19A and 19B are diagrams schematically showing a medium on which content is edited when the My Disc is not loaded. FIG. 19A is a diagram in which the Disc 1 is loaded. The medium to be edited is shown, and (b) shows the reflection of the changed portion on the disc 1 when the disc 1 is loaded.

  In the case of the state shown in FIG. 16, among the contents 1 to 3 represented by the titles 1 to 3 recognized in the back end unit 200, the contents 1 and 2 recorded in the area 1 of the storage unit 340. The same editing process as when the disc 1 is loaded can be performed.

  That is, as shown in FIG. 19B, when the content 2 of the disc 1 is changed in another recorder device, the drive control unit 320 records the change of the content 2 in the disc 1 in the area 1. It is reflected to the content 2 that is present. At this time, the map table recorded in entry 1 is also updated.

<Content copy operation>
Next, a content copying operation in the recorder apparatus 100 will be described below with reference to FIGS. 20 (a) and 20 (b). Here, the in-memory copy operation in the storage unit 340 in the recorder apparatus 100 will be described as an example. The in-memory copy operation can also be referred to as an in-memory dubbing operation in the recorder apparatus 100. 20A and 20B are diagrams showing the in-memory copy process in the recorder apparatus 100, and FIG. 20A is a diagram showing the state of the storage unit 340 after the in-memory copy process. (B) is a figure which shows the state of the title management area in the memory | storage part 280 after an in-memory copy process.

  The content in-memory copy process is a process executed in response to a content copy instruction from the user via the operation input unit. For example, when the user selects a title from the titles displayed on the display device and determines in which area the selected title is to be copied, the back-end control unit 240 displays the content represented by the selected title. When an instruction to copy to the area in the selected storage unit 340 is received, the in-memory copy process of the content is executed. Note that the title displayed on the display device is a title recognized by the back-end unit 200. The title recognized in the back-end unit 200 can be rephrased as the title registered in the title management table recorded in the title management area of the storage unit 280.

  Upon receiving an instruction from the user to copy the content 2 recorded in the area 1 of the storage unit 340 to the area 2 of the storage unit 340, the back-end control unit 240 is recorded in the area 1 with respect to the drive control unit 320. The content 2 is recorded in the area 2. Upon receiving the instruction from the back-end control unit 240, the drive control unit 320 records the content 2 in the area 2 as shown in FIG. At this time, the drive control unit 320 updates the map table recorded in the entry 2. The recording of the content 2 in the area 2 and the update of the map table associated therewith are the same as the processing described in the recording operation, and thus the description thereof is omitted.

  When the recording of the content 2 in the area 2 is completed, the back-end control unit 240 subtracts 1 from the remaining dubbing count of the content 2 in the title management information recorded in the title management area of the disc 1 in the storage unit 280. Further, 1 is added to the remaining dubbing count of the content 2 in the title management information recorded in the title management area of the disc 2 in the storage unit 280. Accordingly, as shown in FIG. 20B, the remaining dubbing count of the content 2 in the title management area of the disc 1 is “8”, and the remaining dubbing count of the content 2 in the title management area of the disc 2 is “1”. It becomes.

  As shown in FIG. 20A, since the disc 2 is not loaded in the drive unit 300, the synchronization state of the content 2 recorded in the area 2 is information indicating unsynchronization.

<Unregister My Disk>
Next, the registration cancellation process of My Disk will be described. The drive control unit 320 that has received an instruction to cancel the registration of the disk 1 from the user erases the management information that is recorded in the storage unit 340 and manages the area associated with the disk 1 that is to be deregistered. That is, the media ID information, the media key information, and the map information in the entry are deleted, and the allocation flag is changed to “0” indicating that the allocation is not performed. If data is recorded in the area, the recorded data is also erased. As a result, the entry in the storage unit 340 is in a state where a new My Disk can be registered.

  Further, the back-end control unit 240 that has received the instruction to cancel the registration of the disc 1 from the user deletes the title management information recorded in the title management area of the disc 1 in the storage unit 280. As a result, the back end unit 200 cannot recognize the title indicating the content recorded on the disc 1.

(Using the file system of My Disk)
In the recorder device 100, it is preferable to use a file system acquired from an optical disk registered as My Disk for writing data to and reading data from the optical disk registered as My Disk.

  Here, data management using an optical disk file system will be described below with reference to FIGS. 21A to 21C. FIGS. 21A to 21C are diagrams showing data management using a file system. FIG. 21A shows an example of a file system recorded in the storage unit 280. FIG. Shows the correspondence relationship of the recording state of the disc 1 corresponding to the recording state of the content in the area 1, and (c) is a diagram showing a map table for each file.

  Normally, a file system defined by a standard for each type of optical disk is recorded in the optical disk, and each file recorded on the optical disk is associated with the recorded address of each file by the file system. ing. The file system is often recorded at the beginning of the recording area of the optical disc.

  The back-end unit 200 refers to the file system acquired from the optical disk in order to specify the address of the optical disk that is the target of data reading or data writing. The file system is acquired together with the media ID and the like when the optical disc is loaded, and is stored in the volatile memory of the back end unit 200. Further, in order to cope with an unexpected power interruption, the acquired file system is also stored in the storage unit 280 ((a) of FIG. 21). The back-end unit 200 acquires a file system from the optical disk every time an optical disk is loaded, and compares the acquired file system with the file system recorded in its own apparatus to maintain the latest state of the file. I am doing so.

  That is, the back-end unit 200 compares the file system read from the optical disk registered as My Disk with the file system already recorded in the storage unit 280 (the file system most recently read from the optical disk). As a result, the back-end unit 200 acquires content information recorded on the optical disc and not recorded in the storage unit 340 (for example, the address of the optical disc on which the content is recorded, title information indicating the content, etc.).

  In FIG. 21A, only the file system related to the disk 1 is shown, but the file system is recorded in the file system management area of the storage unit 280 by the number of disks registered as my disks. ing.

  Thus, by recording the file system of the optical disc registered as My Disc in the storage unit 280, the back end unit 200 is recorded in the storage unit 280 even when the optical disc is not loaded. The file on the virtual disk image can be accessed by referring to the existing file system. That is, even when the My Disk is not loaded, the data can be handled as if the My Disk is loaded. For example, in the map information of the storage unit 340, when the address of the storage unit 340 corresponding to the virtual address to be accessed is recorded, the data recorded at the address using the address of the storage unit 340 Can be read out.

  Further, as shown in FIG. 21B and FIG. 21C, even when the content 1 is divided into a plurality of fragmented files and recorded on the optical disc, the back-end control unit 240 can access the content 1 accurately by referring to the arrangement information of the content 1 in the file system recorded in the storage unit 280.

  As described above, the map information recorded in the storage unit 340 is shown as arrangement information for each content in the present embodiment, but more precisely, as shown in FIG. ) Shows the arrangement information for each.

  In addition, when the registration of My Disk is canceled, the file system recorded in the file system management area is also deleted together with the title management information.

<Example of display on display device>
Finally, a display example of content and information recorded in the title list on the display device connected to the recorder device 100 will be described below with reference to FIG. FIG. 22 is a diagram schematically showing display of information recorded in the content and title list on the display device 500.

  When the user instructs the recorder apparatus 100 to display a title list via the operation input unit, the display apparatus 500 displays the title list and content as shown in FIG.

  That is, as shown in FIG. 22, the display screen in the display device 500 includes two screens: a content display unit 510 that continues to display content that has been viewed so far, and a title list display unit 520 that displays a title list. Will be divided.

  The title list display unit 520 displays tabs corresponding to registered My Disks as shown in FIG. When the user selects the tab of the My Disc for which the title list is desired to be confirmed, the title list display unit 520 displays the title list of the My Disc selected by the user. That is, the information of the title management table recorded in the title management area of each My Disc in the storage unit 280 is displayed.

  FIG. 22 shows a title list when the tab of the disc 1 is selected. At this time, it is preferable to display information (icon) indicating the selected disk on the display unit 530. When the user selects each title displayed on the title list display unit 520, it is preferable to display a thumbnail of the content indicated by the temporarily selected title on the display unit 530.

<Advantages of Recorder Device 100>
The optical disc drive device (drive unit 300) provided in the recorder device 100 according to the present embodiment is
A write command for writing content data to a specific area on a designated disc designated by a user among a plurality of pre-registered optical discs, which is an optical disc drive device having a non-removable recording medium (storage unit 340) Writing means (drive control unit) that writes the content data to the recording medium and records the area on the recording medium in which the content data is written and the specific area on the designated disc in association with each other. 320), when the designated disc is loaded, the content data written on the recording medium is written into a specific area on the designated disc, and the writing completion notification of the content data is sent to the issuer of the write command. And a synchronization means (drive control unit 320) for issuing It is a 憶 apparatus.

  That is, in the drive unit 300 provided in the recorder device 100, the area 1 on the storage unit 340 in which content data to be written to a specific area of the disc 1 is written and the specific area on the disc 1 are associated with each other. When data is recorded and the disc 1 is loaded, the content data written on the storage unit 340 is written to a specific area on the disc 1 and the writing of the content data to the back-end unit 200 instructed to write the content data is completed. Issue a notification.

  As described above, the drive unit 300 can write the content data to be written to the disc 1 in the area 1 of the storage unit 340 as if it were recorded on the disc 1.

  Therefore, when the drive unit 300 writes content data from the region 1 of the storage unit 340 to the disc 1 when the disc 1 is loaded, the content data is transferred from the region 1 of the storage unit 340 to the disc 1 in a bit-to-bit (Bit to Bit). That is, the drive unit 300 can reduce the time required for writing content from the storage unit 340 to the disc 1 when content data to be written to the disc 1 is written to the storage unit 340.

  Even if the disc 1 is not loaded, the back-end unit 200 can write content data to the disc 1 only by supplying a single write command to the drive unit 300.

<Warning display when playing unsynchronized content>
Finally, warning display when playing back unsynchronized content will be described in detail with reference to FIGS. 23 (a) to 23 (c).

  4A and 4B are diagrams illustrating reproduction of unsynchronized content in the recorder device 100, where FIG. 5A schematically illustrates a storage unit and a loaded disc, and FIG. 5B schematically illustrates title selection in a title list display unit 520. FIG. (C) is a diagram schematically showing the content display unit 510 during reproduction of unsynchronized content.

  As shown in FIG. 23A, content 1 and content 2 are recorded in area 1 of storage unit 340. The disc drive unit 330 is currently loaded with the disc 1, and both the content 1 and the content 2 are synchronized with the disc 1. The content 1 is recorded in the area 2 of the storage unit 340, but the content 1 recorded in the area 2 is not synchronized with the disc 2 because the disc 2 is not loaded in the disc drive unit 330. Unsynchronized content.

  At this time, since the content data of the content 1 exists in the area 2 of the storage unit 340, the recorder device 100 can reproduce the content 2. The back end unit 200 controls the drive unit 300 to read the content data of the content 2 from the disc 2, but the drive unit 300 reads the content data of the content 2 from the area 2 of the storage unit 340.

  When the user instructs to play the content 1 recorded in the disc 2 (actually, recorded in the area 2 of the storage unit 340) as shown in FIG. The unit 240 supplies a read command to the drive unit 300 to read the content 1 from the disc 2. At this time, the back-end control unit 240 reads from the drive unit 300 because the synchronization status of the content 1 is not synchronized in the title management table recorded in the title management area of the disc 2 recorded in the storage unit 280. The data of the issued content 1 is reproduced, and a warning indicating that the content 1 is not synchronized is issued.

  As a warning indicating that the content 1 is not synchronized, a warning sound may be output from the recorder device 100 (or a speaker device connected to the recorder device 100), or a warning lamp such as an LED is turned on. You may make it let it. Among these, as shown in (c) of FIG. 23, it is preferable that the warning image is superimposed on the image (moving image) of the content 1 and displayed on the display device 500. By displaying on the display device 500, the user can easily recognize that the content 1 is not synchronized.

  In FIG. 23 (c), the case where the text “Please insert Disc 2” is shown as an example. However, the present invention is not limited to this example. Such an image may be displayed.

  Further, the display of the warning indicating that the content 1 is not synchronized is not limited to the display device 500 connected to the recorder device 100, and the recorder device 100 has a built-in information display unit such as a small liquid crystal display device. If the warning can be confirmed by the user, the information may be displayed on the built-in information display unit.

  In this way, when content is played (i.e., when a user views the content), by alerting the user related to the content by alerting that the content synchronization is not complete Only a warning can be issued indicating that synchronization is not complete. That is, it is possible to improve usability (usability) in the recorder apparatus 100 in which the content data recorded in the storage unit 340 is written to the optical disc.

(Additional notes)
In the present embodiment, the case where the title management table of each My Disc is recorded in the storage unit 280 has been described as an example, but the title management table of each My Disc is recorded in the storage unit 340. Also good.

  In this case, when playing back unsynchronized content, the drive unit 300 supplies information indicating that playback (content from which data is read) to the backend unit 200 is unsynchronized. It ’s fine.

(Program and recording medium)
The back-end control unit 240 and the drive control unit 320 included in the recorder device 100 may be configured by hardware logic. Alternatively, it may be realized by software using a CPU (Central Processing Unit) as follows.

  That is, the back-end control unit 240 and the drive control unit 320 have a CPU such as an MPU that executes instructions of a program that realizes each function, a ROM (Read Only Memory) that stores the program, and a format that can execute the program. A RAM (Random Access Memory) to be developed and a storage device (recording medium) such as a memory for storing the program and various data are provided.

  The object of the present invention is not limited to the case where the program memory of the back-end control unit 240 and the drive control unit 320 is fixedly supported, but the program code (execution format program, intermediate code program, or This can also be achieved by supplying a recording medium in which the source program) is recorded to the recorder apparatus 100, and the recorder apparatus 100 reads out and executes the program code recorded in the recording medium.

  The recording medium is not limited to a specific structure or type. That is, the recording medium includes, for example, a tape system such as a magnetic tape and a cassette tape, a magnetic disk such as a floppy (registered trademark) disk / hard disk, and an optical disk such as a CD-ROM / MO / MD / DVD / CD-R. System, a card system such as an IC card (including a memory card) / optical card, or a semiconductor memory system such as a mask ROM / EPROM / EEPROM / flash ROM.

  Further, the object of the present invention can be achieved even if the back-end control unit 240 and the drive control unit 320 (or the recorder device 100) are configured to be connectable to a communication network. In this case, the program code is supplied to the back-end control unit 240 and the drive control unit 320 via the communication network. The communication network is not limited to a specific type or form as long as it can supply program codes to the back-end control unit 240 and the drive control unit 320. For example, it may be the Internet, intranet, extranet, LAN, ISDN, VAN, CATV communication network, virtual private network, telephone line network, mobile communication network, satellite communication network, or the like.

  The transmission medium constituting the communication network may be any medium that can transmit the program code, and is not limited to a specific configuration or type.
