Information recording apparatus, information recording method, program storage medium, and program

An information recording method, comprising:

• recording a file and file system information on a recording medium;
• generating the file system information for an application software program that uses the file;
• and
• controlling the recording to allocate the file system information to virtual addresses as one file, wherein,
• when the file is to be recorded in the recording, the recording is controlled in the controlling to extract, from the recording medium, previous file system information including previous file system information concerning files not managed by the application software program and previous file system information concerning files managed by the application software program, to make the previous file system information concerning the files managed by the application software program unreadable, to update the previous file system information concerning the files managed by the application software program based on the file, and to record the updated previous file system information concerning the files managed by the application software program on the recording medium, adjacent, in the virtual addresses, to a file used for playing back the file to be recorded.

A non-transitory, program storage medium storing a computer-readable program, wherein the program, when executed by a processor, causes the processor to perform a method comprising:

• controlling a recording of a file and file system information on a recording medium;
• controlling a generation of the file system information for an application software program that uses the file;
• and
• controlling the controlling the recording to allocate the file system information to virtual addresses as one file, wherein,
• when the file is to be recorded in the controlling the recording, the controlling the recording is controlled in the controlling the controlling to extract, from the recording medium, previous file system information including previous file system information concerning files not managed by the application software program and previous file system information concerning files managed by the application software program, to make the previous file system information concerning the files managed by the application software program unreadable, to update the previous file system information concerning the files managed by the application software program based on the file, and to record the updated previous file system information concerning the files managed by the application software program on the recording medium, adjacent, in the virtual addresses, to a file used for playing back the file to be recorded.

An information recording apparatus, comprising:

• a recorder configured to record a file and file system information on a recording medium;
• a file system information generator configured to generate the file system information for an application software program that uses the file;
• and
• an operation controller configured to control the recorder to allocate the file system information to virtual addresses as one file, wherein,
• when the file is to be recorded by the recorder, the operation controller controls the recorder to extract, from the recording medium, previous file system information including previous file system information concerning files not managed by the application software program and previous file system information concerning files managed by the application software program, to make the previous file system information concerning the files managed by the application software program unreadable, to update the previous file system information concerning the files managed by the application software program based on the file, and to record the updated previous file system information concerning the files managed by the application software program on the recording medium, adjacent, in the virtual addresses, to a file for playing back the file to be recorded.
