  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 17 is a diagram showing a schematic configuration of an information recording / reproducing apparatus (home server) according to an embodiment of the present invention. As shown in FIG. 17, the information recording / reproducing apparatus includes a recording / reproducing control module 1, a setting module 2, a management module 3, and a data input / output control module 4.

  The information recording / reproducing apparatus is connected to, for example, a plurality of HDDs (hard disk drives), and records in a connected storage area (recording area 3-3 shown in FIG. 3) formed by connecting the recording media of the plurality of HDDs. Data (video content) can be recorded, and recorded data recorded in the linked storage area can be reproduced. That is, the recording / reproducing control module 1 controls recording of recording data in a concatenated storage area formed by concatenating recording media of a plurality of HDDs, and controls reproduction of recording data recorded in the concatenated storage area. To do.

  The management module 3 is connected to a plurality of HDDs, manages the start position and length (or size) of the linked storage area formed by linking the recording media of the plurality of HDDs. Alternatively, the start position and length (or size) of a plurality of free areas (reserved extents) are managed. Furthermore, the management module 3 manages the start position and length (or size) of one or more data recorded areas in the linked storage area. That is, the management module 3 can manage the recording location of each recording data (each title).

  The setting module 2 has one or more data storage areas (recording reserves for recording the recording data in one or more empty areas based on the size of the recording data and each size of the one or more empty areas. Set the extent. The recording data is recorded in the set one or a plurality of data storage areas by the recording control by the recording / reproducing control module 1.

  The data input / output control module 4 inputs recording data provided from the outside to the management module 3 based on the recording control of the recording / playback control module 1, or from the management module 3 based on the playback control of the recording / playback control module 1. Output the provided recording data to the outside.

  When the information recording / reproducing apparatus is activated, the management module 3 extracts one or a plurality of empty areas (one or a plurality of reserved extents) in each HDD (each recording medium), and stores each recording medium of the plurality of HDDs. One or a plurality of free areas (one or a plurality of reserved extents) in the concatenated storage area formed by concatenation are managed.

  For example, the management module 3 extracts one or a plurality of free areas (one or a plurality of reserved extents) of a recording medium of a predetermined HDD based on the bitmap table 2-2 illustrated in FIG. The bitmap table 2-2 corresponds to the recording area 2-1 of the recording medium of a predetermined HDD, and manages the usage state of the minimum access unit (logical block (LB)) of the recording area 2-1. For example, bit 1 is set for used (data recorded) LB, and bit 0 is set for unused (data not recorded) LB. Furthermore, one or a plurality of free areas (one or a plurality of reserved extents) of a recording medium of a predetermined HDD are managed by the reserved extent management information 2-3. The reserved extent management information 2-3 includes the head position and size information of each free area, and manages the free areas (reserved extents) in the order of addresses.

  As shown in FIG. 3, the recording media 3-1 of the HDDs are simply connected to form a recording area 3-3. The recording area 3-3 is an area formed by the recording media 3-11, 3-12, 3-13 of each HDD, and is centrally managed by a logical block number (LB). The recording medium management information 3-2 manages the number of recording media and the size of each recording medium. The reserved extent management information 3-4 includes the head position and size information of the free area in the recording area 3-3. That is, the free area in the recording area 3-3 is accurately managed by the reserved extent management information 3-4.

  On the other hand, the setting module 2 calculates a size necessary for recording the video content based on the size of the video content (recording data). If the clear size of the video content is not known, the setting module 2 estimates the size of the video content based on the average data rate and recording time of the video content. Furthermore, the setting module 2 performs video for one or more reserve extents based on the calculated size (or estimated size) and each size of one or more reserve extents in the recording area 3-3. One or a plurality of recording reserve extents for recording contents are set. That is, the setting module 2 secures a recording reserve extent of the calculated size (or estimated size) in one or a plurality of reserve extents. Note that the recording reserved extent is managed by the recording reserved extent management information 3-5.

  Further, the recording / playback control module 1 controls the recording order of the video content with respect to each HDD including the plurality of recording reserve extents, for example, based on the setting of a plurality of recording reserved extents, and each HDD based on the recording order. Video content is recorded in the reserved extent for recording.

  For example, the recording area 3-3 is centrally managed by the logical block number. That is, each recording reserve extent is also managed by the logical block number, and the use order of each recording reserved extent can be determined by the logical block number of each recording reserved extent. For example, a first reserved recording extent and a second reserved recording extent are included in the first HDD, and a third reserved recording extent is the second. It is assumed that the fourth reserved recording extent included in the HDD is included in the third HDD. In this case, the recording / reproducing control module 1 controls the recording order as follows. That is, the recording / playback control module 1 records the video content on the first HDD (the first recording reserve extent and the second recording reserve extent used), and then the second HDD. In the second HDD (the third recording reserve extent used), and then in the third HDD (the fourth recording reserve extent used).

  FIG. 1 is a functional block diagram showing the function of each module of the information recording / reproducing apparatus shown in FIG. The recording / playback control module 1 controls the recording / playback / copy / editing function 1-2. The management module 3 also includes a setting function 1-1, a recordable range setting function 1-3, a title / file deletion function 1-4, a recording medium initial registration function 1-5, a recording medium alternative registration function 1-6, a recording The media removal function 1-7 and the failure detection function 1-8 are controlled.

  The recording medium initial registration, alternative registration, and removal are executed by the setting function 1-1, the recording medium initial registration function 1-5, the recording medium alternative registration function 1-6, and the recording medium removal function 1-7. At the initial registration, alternative registration, and removal of the recording medium, the data input / output control module 4 outputs display information for displaying the media setting screen shown in FIGS.

  In the case of new registration, as shown in the media setting screen 9-1 in FIG. 9, the user selects the blank next to No. 2 from the registration media list on the left, and selects the new registration media from the new / alternative media list on the upper right. After selecting, select the new registration button in the lower right. As a result, as shown in the media setting screen 9-2 in FIG. 9, the new media (NO3) is registered in the registered media list on the left side.

As a result, as shown in the media setting screen 10-2 in FIG. 10, the defective media (NO2) is removed from the registered media list on the left side.

  At this time, as shown in the media setting screen 11-1 in FIG. 11, if deletion of the defective title is selected by the user, when the defective media is removed as shown in the media setting screen 11-2 in FIG. The title of the content in which the part is recorded and the title of the content in which the entire content is recorded are deleted from the reproduction list. Since the playlist includes the titles of all the contents recorded on a plurality of registered media, the titles and all of the contents partially recorded on the defective media are recorded by the above deletion. The content title cannot be selected and played back.

  Alternatively, as shown in the media setting screen 12-1 in FIG. 12, if the user selects the repair of the defective title, the defective media is identified when the defective media is removed as shown in the media setting screen 12-2 in FIG. The title of the content in which the part is recorded (defective title) and the title of the content in which the entire content is recorded (defective title) are copied to another medium.

  Further, when registering an alternative medium in place of the removed medium, the user selects “Removed” from the registered media list and displays the alternative medium from the new / alternative media list as shown in the media setting screen 13-1 in FIG. 13. After selecting, select an alternative button. As a result, as shown in the media setting screen 13-2 of FIG. 13, the alternative media (NO2) is registered in the registration media list on the left side.

  As shown in FIG. 4, in a state where the first recording medium 4-41 and the second recording medium 4-42 are registered, the recording medium management information 4-3 is the start of the first recording medium 4-41. LBN (L1) and size (S1), and the start LBN (L2) and size (S2) of the second recording medium 4-42 are included. Further, when the third recording medium 4-43 is additionally registered, the recording medium management information 4-3 stores the start LBN (L1) and size (S1) of the first recording medium 4-41 and the second recording medium. In addition to the start LBN (L2) and size (S2) of the medium 4-42, the start LBN (L3) and size (S3) of the third recording medium 4-43 are included. Correspondingly, the bitmap table 4-1 is expanded and the recording capacity is increased.

  As shown in FIG. 5, in a state where the first recording medium 5-31, the second recording medium 5-32, and the third recording medium 5-33 are registered, the recording medium management information 5-7 includes: The start LBN (L1) and size (S1) of the first recording medium 5-31, the start LBN (L2) and size (S2) of the second recording medium 5-32, and the third recording medium 5-33 Includes start LBN (L3) and size (S3).

  Here, when removal of a defective medium (for example, the second recording medium 5-32) is executed by the recording medium removal function 1-7 as shown in FIG. 10, the recordable range as shown in FIG. The size of the second recording medium included in the recording medium management information 5-7 is set to 0 by the setting function 1-3, and the recording area of the second recording medium among all the bits of the bitmap table 5-1 The bit corresponding to is set to 0. That is, all the recording areas of the second recording medium 5-32 are registered as used.

  As shown in FIG. 6, in a state where the first recording medium 6-31, the second recording medium 6-32, and the third recording medium 6-33 are registered, the recording medium management information 6-7 includes The start LBN (L1) and size (S1) of the first recording medium 6-31, the start LBN (L2) and size (S2) of the second recording medium 6-32, and the third recording medium 6-33 Includes start LBN (L3) and size (S3).

As described above, the size of the second recording medium included in the recording medium management information 6-7 is set to 0 by the recordable range setting function 1-3, and the second of all the bits in the bitmap table 6-1. The bit corresponding to the recording area of the recording medium 6-32 is set to 0. That is, all the recording areas of the second recording medium 6-32 are registered as used. Furthermore, the defective titles (title A and title B) recorded on the second recording medium 6-32 are also transferred to the other recording media (first recording medium 6-31 and third recording medium 6-33). When the recording is performed in a distributed manner, the recording area of the defective title on other recording media is managed as an empty area. That is, the bit corresponding to the recording area of the defective title on the recording medium other than the second recording medium among all the bits of the bitmap table 6-1 is set to 1.

  As shown in FIG. 7, in a state where the first recording medium 7-31 and the third recording medium 7-33 are registered, the recording medium management information 7-7 is stored in the first recording medium 7-31. The start LBN (L1) and size (S1), and the start LBN (L3) and size (S3) of the third recording medium 7-33 are included. Alternatively, as shown in FIG. 8, in a state where the first recording medium 8-31 and the third recording medium 8-33 are registered, the recording medium management information 8-7 includes the first recording medium 8- 31 start LBN (L1) and size (S1), and the start LBN (L3) and size (S3) of the third recording medium 8-33.

  Here, when the recording medium replacement registration function 1-6 performs registration of the replacement medium 7-32 in place of the defective medium (second recording medium) as shown in FIG. 13, as shown in FIG. In addition, the recording medium management information 7-7 is updated. Alternatively, when the recording medium replacement registration function 1-6 performs registration of the replacement medium 8-32 in place of the defective medium (second recording medium) as shown in FIG. 13, as shown in FIG. The recording medium management information 8-7 is updated.

  If the size of the recording area of the defective medium and the size of the recording area of the alternative medium are the same, the replacement is performed while maintaining the start LBN (L2) of the second recording medium included in the recording medium management information. The size of the recording area of the media is adopted. That is, the size of the second recording medium is maintained as it is. Also, the bit corresponding to the recording area of the second recording medium (= the recording area of the alternative medium) among all the bits of the bitmap table is set to 1. That is, the recording area of the second recording medium (= the recording area of the alternative medium) is all registered as unused.

  As shown in FIG. 8, when the recording area size (S22) of the alternative medium 8-32 is larger than the recording area size (S2) of the defective medium (second recording medium), the recording medium management information 8- 8, while maintaining the start LBN (L 2) of the second recording medium included in 8, the size (S 2) of the recording area of the second recording medium instead of the recording area size (S 22) of the alternative medium 8-32. ) Is adopted. That is, the size (S2) of the second recording medium is maintained as it is. In this case, an address assigned to the entire recording area of the second recording medium is allocated to a part of the recording areas of the entire recording area of the alternative medium 8-32, and the alternative medium 8-32 Only a part of the entire recording area can be used (accessed). In addition, the bit corresponding to the recording area of the second recording medium (= partial recording area of the alternative medium 8-32) among all the bits of the bitmap table 8-1 is set to 1. That is, a partial recording area of the alternative medium is registered as unused. Note that the start LBN (L3) of the third recording medium 8-33 is maintained as it is.

  As shown in FIG. 7, when the size (S21) of the recording area of the alternative medium 7-32 is smaller than the size (S2) of the recording area of the defective medium (second recording medium), the recording medium management information 7- 7 adopts the size (S21) of the recording area of the alternative medium 7-32 instead of the size (S2) of the second recording medium while maintaining the start LBN (L2) of the second recording medium included in 7 Is done. That is, the size (S2) of the second recording medium is changed. In this case, the addresses assigned to a part of the recording area of the defective medium are allocated to all the recording areas of the alternative medium 7-32, and a recording area smaller than the recording area of the defective medium can be used (accessed). ) The bit corresponding to the partial recording area of the second recording medium (= the entire recording area of the alternative medium 7-32) among all the bits of the bitmap table 7-1 is set to 1, and the remaining recording area The corresponding bit is set to 0. That is, a partial recording area of the second recording medium (= all recording areas of the alternative medium 7-3) is registered as unused, and the remaining recording area is registered as used. Note that the start LBN (L3) of the third recording medium 7-33 is maintained as it is.

  The recording / reproducing / copying / editing function 1-2 refers to the bitmap table set by the recordable range setting function 1-3, and the recording data is recorded on the reserved extent, and the recording data is reproduced. The recorded data is edited. The target of recording / playback / editing is centrally managed by the LBN assigned to the linked information storage area. According to the procedure shown in FIG. 16, the recording medium to be actually accessed and the position information are obtained.

  First, each variable is initialized (ST16-1), and the process is repeated for each recording medium until the actual access position is determined (ST16-2). It is confirmed whether or not the next recording medium i + 1 exists (ST16-3). If the next recording medium does not exist (ST16-3, NO), whether or not P is smaller than the size of the recording medium i is determined. Judgment is made (ST16-5). When P is smaller than the size of the recording medium i (ST16-5, YES), it is determined that it is included in the last recording medium, and the target recording medium number Mn and the position information P in the recording medium are set. (ST16-9).

  When the next recording medium exists (ST16-3, YES), and when it is determined that P is not included in the current recording medium range (ST16-4, YES), the current medium range from P The size is subtracted (ST16-6), the number of the current recording medium is incremented (ST16-8), and the processes after ST16-2 are repeated again. If it is determined that P is included in the current media range (ST16-4, NO), the target recording medium number Mn and the position information P in the recording medium are set in the same manner as before (ST16-9).

  When the failure detection function 1-8 determines that the predetermined recording medium is defective, the setting function 1-1 takes out the predetermined recording medium or sets an alternative medium in place of the predetermined recording medium. Done.

  Next, with reference to the flowchart shown in FIG. 14, the defective media exclusion process and the defective media title deletion process will be described.

  First, it is determined whether or not there is a change in the recording medium (ST14-1). When there is a change in the recording medium (ST14-1, YES), for example, when newly registering a recording medium (ST14-2, YES), the start LBN of the newly registered recording medium is recorded with respect to the recording medium management information. The size is additionally registered (ST14-3). Also, the bitmap table is expanded corresponding to the new registration of recording media (ST14-5).

  When the replacement medium is replaced and registered instead of the defective medium (ST14-2, NO) and the size of the recording area of the replacement medium is the same as the size of the recording area of the defective medium. If the size of the recording area of the alternative medium is larger than the size of the recording area of the defective medium (ST14-4, YES), the start LBN of the defective medium in the recording medium management information is maintained as it is, and the size of the defective medium is also It is maintained as it is (ST14-6). Also, the bit corresponding to the recording area of the defective medium in the bitmap table is set to 1 (ST14-5).

  In the case where the replacement medium is replaced and registered instead of the defective medium (ST14-2, NO), and the size of the recording area of the replacement medium is smaller than the size of the recording area of the defective medium. (ST14-4, NO), the start LBN of the defective medium in the recording medium management information is maintained as it is, and the size of the defective medium is changed to the size of the recording area of the alternative medium (ST14-7). In addition, the bit corresponding to the partial recording area of the defective media in the bitmap table (= all recording areas of the alternative media) is set to 1, and the bits corresponding to the remaining recording areas of the defective media in the bitmap table are set to 0. (ST14-5).

  When there is no change in the recording medium (ST14-1, NO) or when the setting of the bitmap table is completed (ST14-5), the recording area of each recording medium is recorded based on the recording medium management information and the bitmap table. The recording data is recorded or the recording data is reproduced (ST14-8).

  If the recording / playback process ends normally (ST14-9, YES), the defective media exclusion process and the defective medium title deletion process end. Before the recording / playback process ends normally, a defective medium is detected (ST14-10, YES), and when a title is recorded on the defective medium (ST14-11, YES) (ST14-12, YES). Then, the title recorded on the defective medium is registered in the deletion list (ST14-13).

  When all titles recorded on the defective media are registered in the deletion list (ST14-11, NO) and deletion of titles recorded on the defective media is set (ST14-14, YES), the deletion list The title registered in is deleted (ST14-15). Correspondingly, the bit corresponding to the recording area of the defective medium in the bitmap table is set to 0. That is, all the recording areas of the defective media are set as used (ST14-16). In addition, when titles recorded on defective media (defective titles) are distributed and recorded on other recording media, the recording area of defective titles on other recording media is managed as an empty area. That is, the bit corresponding to the recording area of the defective title on the recording medium other than the defective medium in the bitmap table is set to 1.

  Thereafter, removal of the defective medium is permitted, and the defective medium is extracted (ST14-17).

  If a sign of failure is detected from the predetermined recording medium before it is determined that the predetermined recording medium is defective, the title recorded on the predetermined recording medium is changed to a recording medium other than the predetermined recording medium. You may make it copy to.

  For example, as shown in the flowchart of FIG. 15, when a failure sign is detected from a predetermined recording medium (ST15-10, YES) and a title is recorded on the predetermined recording medium (ST15-11, YES) (ST15-12, YES), the title recorded on the predetermined recording medium is registered in the deletion list (ST15-13).

  When all titles recorded on a predetermined recording medium are registered in the deletion list (ST15-11, NO), the bit corresponding to the recording area of the predetermined recording medium in the bitmap table is set to zero. That is, all the recording areas of the predetermined recording medium are set as used (ST15-14). Furthermore, when the relief of the title recorded on the predetermined recording medium is set (ST15-15, YES), the title registered in the deletion list is copied to a recording medium other than the predetermined recording medium ( ST15-16). Thereafter, the title recorded on the predetermined recording medium is deleted (ST15-17).

  As described above, the following effects can be obtained.

  (1) Even if the failed medium is removed, it is possible to access other media excluding the failed medium without causing a change in the address space of the entire recording medium array.

  (2) If the title to be deleted recorded on the faulty media is recorded in a distributed manner on other media, not only the title to be deleted recorded on the faulty media but also the other media It is possible to wipe out the titles to be deleted that are distributed and recorded. Thereby, the recording area of the entire recording media array can be used efficiently.

  (3) When the size of the recording area of the alternative media attached instead of the failed media is the same as the size of the recording area of the failed media, the start LBN and size of the failed media included in the recording media management information are used as they are. To do. As a result, the LBN assigned to the entire recording media array can be continuously used as it is.

  (4) Even when the size of the recording area of the alternative media attached instead of the failed media is larger than the size of the recording area of the failed media, the start LBN and size of the failed media included in the recording media management information are used as they are. To do. As a result, the LBN assigned to the entire recording media array can be continuously used as it is.

  (5) When the size of the recording area of the alternative media attached instead of the failed media is smaller than the size of the recording area of the failed media, the start LBN of the failed media included in the recording media management information is used as it is. Change the size of the failed media to the alternate media size. As a result, the LBN assigned to the entire recording media array can be used continuously as it is.

  The module described above may be realized by hardware, or may be realized by software using a CPU or the like.
