Recording medium, recording device usint the same, and reproduction device

A recording method, comprising:

• recording contents information as a file onto a recording medium using file system information having a directory hierarchy structure capable of being referenced using a path name;
• recording contents management information for managing the directory and the file, onto the recording medium;
• and
• recording extension information with respect to the directory and the file, onto the recording medium,
• wherein the contents management information includes:
• media object management information for referencing the directory and the file using object reference information obtained by converting the path name;
• and
• extended object management information for managing the extension information,
• wherein the recording method comprises associating the directory and the file with the extension information via the object reference information.

A recording medium recording information, recorded with:

• file system information for managing the information as a directory hierarchy structure capable of being referenced using a path name;
• contents management information for managing the directory and the file;
• and
• extension information with respect to the directory and the file,
• wherein the contents management information includes:
• media object management information for referencing the directory and the file using object reference information obtained by converting the path name;
• and
• extended object management information for managing the extension information,
• wherein the directory and the file are associated with the extension information via the object reference information.

A program for controlling a recording operation of a recording apparatus for recording information onto a recording medium, the program comprising an instruction for causing the recording apparatus to execute:

• recording contents information as a file onto a recording medium using file system information having a directory hierarchy structure capable of being referenced using a path name;
• recording contents management information for managing the directory and the file, onto the recording medium;
• and
• recording extension information with respect to the directory and the file, onto the recording medium,
• wherein the contents management information includes:
• media object management information for referencing the directory and the file using object reference information obtained by converting the path name;
• and
• extended object management information for managing the extension information,
• wherein the program further comprises an instruction for causing the recording apparatus to execute associating the directory and the file with the extension information via the object reference information.

A data structure recorded on a recording medium, comprising:

• file system information for managing contents information recorded on the recording medium as a directory hierarchy structure capable of being referenced using a path name;
• contents management information for managing the directory and the file;
• and
• extension information with respect to the directory and the file,
• wherein the contents management information includes:
• media object management information for referencing the directory and the file using object reference information obtained by converting the path name;
• and
• extended object management information for managing the extension information,
• wherein the directory and the file are associated with the extension information via the object reference information.
