Abstract

A data recording and reproducing configuration in which both of BDMV standard compliant data and BDMV standard non-compliant data can be used is realized. A plurality of directories are set in a recording media, and a recording destination directory is selected according to the types of data. The BDMV standard compliant data is recorded in a BDMV directory, and the BDMV standard non-compliant data, for example, 1080/60p or 3D image data are recorded in a BDAV or BU directory. At the time of data reproducing process, a virtual file system in which the recorded data in the BDMV directory and the recorded data in the BDAV/BU directory are consolidated is constructed to achieve the reproducing process. With this configuration, the recording and reproducing of the BDMV standard compliant data and the BDMV standard non-compliant data are achieved.

selects a first directory set in the recording medium for recording the first application standard compliant data as a recording destination on a priority basis when the data-to-be-recorded is the standard compliant data,

selects a second directory different from the first directory as a recording destination when the data-to-be-recorded is standard non-compliant data and performs a data recording process, and

further creates or renews management information to be applied to the reproduction by a virtual file system in which the recorded data in the first and second directories are consolidated and performs a process of recording the created or renewed management information in the recording medium.

2. The information processing apparatus according to claim 1, wherein the data processing unit

creates or renews the management information including the management information on all the data-to-be-reproduced recorded in the first directory and the second directory as the management information and records the created or renewed management information in the recording medium.

3. The information processing apparatus according to claim 2, wherein the data processing unit

performs a process of creating or renewing the management information including any one of an index file, a movie object file, a playlist file, and a clip information file to be applied to the reproducing process on the basis of the virtual file system and recording the created or renewed management information in the recording medium.

4. The information processing apparatus according to claim 1, wherein the data processing unit

selects the first directory as the recording destination when the data-to-be-recorded is the standard compliant data and is made to be reproducible without applying the virtual file system, and

selects the second directory as the recording destination when the data-to-be-recorded is the standard compliant data and is made to be reproducible only when the virtual file system is applied.

5. The information processing apparatus according to claim 1, wherein the data processing unit

performs, when recording of the data-to-be-reproduced whose recording destination is a directory different from the first directory is executed, a process of adding an entry including a file name indicating recording destination of the data-to-be-reproduced and a file name on the virtual file system in one-to-one correspondence in a file name conversion table included in the management information.

6. The information processing apparatus according to claim 1, wherein the first application standard is a BDMV standard, the first directory is a BDMV directory, and a second directory is a BDAV directory.

7. The information processing apparatus according to claim 6, wherein the directory for recording the management information

is a third directory different from the BDMV directory and the BDAV directory.

8. The information processing apparatus according to claim 1, wherein the first application standard is the BDMV standard, the first directory is the BDMV directory, and the second directory is a directory for recording a BDMV standard non-compliant data and the management information.

9. An information processing apparatus comprising:

a data processing unit configured to perform a data reproducing process from a recording medium, wherein

the data processing unit

copies data-to-be-reproduced set in a directory other than a first directory for recording data compliant with a first application standard set in the recording medium and management information in a local memory, and

constructs a virtual file system in which data in the first directory in the recording medium and the copied data stored in the local memory are consolidated and executes the data reproducing process applied with the virtual file system.

10. The information processing apparatus according to claim 9, wherein

the data processing unit

performs a reproducing process using the management information included in the copy data stored in the local memory as index information on reproducing data at the time of reproducing process applied with the virtual file system.

11. The information processing apparatus according to claim 10, wherein

the data processing unit

performs a process of copying the management information including any one of an index file, a movie object file, a playlist file, and a clip information file to be applied to the reproducing process on the basis of the virtual file system to the local memory, and

performs the reproducing process applied with any one of the index file, the movie object file, the playlist file, and the clip information file stored in the local memory at the time of reproducing process applied with the virtual file system.

12. The information processing apparatus according to claim 9, wherein

the data processing unit

references a file name conversion table included in the management information in the local memory, acquires a file name indicating the recording destination of data from file names on the virtual file system to acquire the data-to-be-reproduced when the data-to-be-reproduced is data stored in the local memory when performing the reproducing process applied with the virtual file system.

13. The information processing apparatus according to claim 9, wherein the first application standard is a BDMV standard, the first directory is a BDMV directory, and

the data processing unit

performs a process of copying the data-to-be-reproduced recorded in a BDAV directory different from the BDMV directory and

the management information recorded in a third directory other than the BDMV and BDAV directories into a local memory.

14. The information processing apparatus according to claim 9, wherein

the first application standard is the BDMV standard, the first directory is the BDMV directory, and

the data processing unit

performs a process of copying the data-to-be-reproduced recorded in a second directory different from the BDMV directly and management information into the local memory.

15. An information recording medium comprising:
