Abstract
The present invention provides a data recording method a data recording and/or reproducing apparatus for recording data transmitted from a computer to a magnetic tape. In case a recording head fails to write data (data ID=582) of fragment ID=5 to a track (track 7), then, the data is rewritten to the first fragment (ID=0) of a next track (track 8). Thus, the data can be rewritten not on the track basis but on the fragment basis, which can reduce loss of tape capacity significantly.
Claims7
A data recording method for recording tracks each composed of a plurality of data blocks each containing recording data to a tape-shaped recording medium, wherein
- each of the data blocks has recorded therein a first identifier to identify the block in the track, and
- each of the data blocks has recorded therein a second identifier to identify the recording data recorded in the data block.
A data recording and/or reproducing apparatus for recording tracks each composed of a plurality of data blocks each containing recording data to a tape-shaped recording medium, comprising:
- means for recording a first identifier to identify the block in the track to each of the data blocks, and
- means for recording a second identifier to identify the recording data recorded in the data block to each of the data blocks.
A recording medium of a tape shape which is to have recorded thereto tracks each composed of a plurality of data blocks each containing recording data, wherein
- each of the data blocks has
- a first area in which a first identifier to identify the block in the track is recorded, and
- a second area in which a second identifier to identify the recording data recorded in the data block.
