Abstract
A recording and reproduction apparatus and method for recording and reproducing different types of data including AV data and PC data on a disc type medium. The type of the recorded data determines the length of recording units used to record the data on the disc. Management information including identification indicating one of the respective types of data is stored at least at two location of a logical volume.
Claims4
A recording and/or reproduction apparatus for recording and/or reproducing different types of data, including AV data and PC data, onto and/or from a disc type recording medium, comprising:
- first recording means for recording said data in recording units of respective lengths;
- and
- second recording means for recording management information to at least two locations of a logical volume,
- said recorded management information including identification information indicating one of a plurality of respective types of data, the type of data being determinative of the length of recording units used to record the data,
- said identification information being redundantly stored in said logical volume.
A file management method for a recording and/or reproduction apparatus for recording and/or reproducing different types of data, including AV data and PC data, onto and/or from a disc type recording medium, comprising the steps of:
- recording said data in recording units of respective lengths;
- and
- recording management information to at least two locations of a logical volume,
- said recorded management information including identification information indicating one of a plurality of respective types of data, the type of data being determinative of the length of recording units used to record the data,
- said identification information being redundantly stored in said logical volume.
A providing medium for providing program which can be read by a computer for causing a recording and/or reproduction apparatus for recording and/or reproducing different types of data, including AV data and PC data, onto and/or from a disc type recording medium to execute the steps of:
- recording said data in recording units of respective length;
- and
- recording management information to at least two locations of a logical volume,
- said recorded management information including identification information indicating one of a plurality of respective types of data, the type of data being determinative of the length of the recording units, said identification information being redundantly stored in said logical volume.
