Claims10
A recording and/or reproduction apparatus for recording and/or reproducing AV data onto and/or from a disc type recording medium, comprising:
- first recording means for recording a file of AV data;
- and
- second recording means for recording management information for the file to at least two locations of a logical volume.
A file management method for a recording and/or reproduction apparatus for recording and/or reproducing AV data onto and/or from a disc type recording medium, comprising:
- a first recording step of recording a file of AV data;
- and
- a second recording step of recording management information for the file to at least two locations of a logical volume.
A providing medium for providing a program which can be read by a computer for causing a recording and/or reproduction apparatus for recording and/or reproducing AV data onto and/or from a disc type recording medium to execute:
- a first recording step of recording a file of AV data;
- and
- a second recording step of recording management information for the file to at least two locations of a logical volume.
A recording and/or reproduction apparatus, comprising:
- unit recording means for recording units of information which can be recorded onto a disc type recording medium;
- setting means for setting lengths of the units of information to be recorded by said unit recording means;
- and
- identification information recording means for recording, in response to a file recorded on the disc type recording medium, identification information for identification of the length of the unit adopted when the file is recorded from among the units of the length set by said setting means.
A file management method for a recording and/or reproduction apparatus for recording and/or reproducing information onto and/or from a disc type recording medium, comprising:
- a unit recording step of recording units of information which can be recorded onto the disc type recording medium;
