Abstract
An information recording medium is provided with a linking loss area having a unit smaller than a unit of block and having a predetermined size is disposed in a recording block used for the replacement by logical overwrite (LOW) or the replacement by defect so as to update data recorded thereon. As a result, the loss of user data capacity which can be practically used for a linking action due to replacement by defect or LOW (Logical Overwrite)-based replacement can be minimized.
Claims35
An information recording medium, comprising:
- a data area provided to record data in recording blocks, wherein a linking loss area having a unit smaller than a unit of a recording block and having a predetermined size is disposed in a recording block used for replacement by logical overwrite for updating data recorded in the data area or replacement by defects occurred in the data area.
A recording apparatus for recording data on an information recording medium, comprising:
- a write/read unit which writes data on the recording medium or reads data from the recording medium;
- and
- a control unit which disposes a linking loss area having a unit smaller than a unit of a recording block and having a predetermined size in the recording block used for replacement by logical overwrite (LOW) to update data recorded on the recording medium or replacement by defects occurred on the recording medium, and which controls the write/read unit to write the recording block on the recording medium.
A reproducing apparatus for reproducing data from an information recording medium, comprising:
- a write/read unit which writes data in the recording medium or reads data from the recording medium;
- and
- a control unit which controls the write/read unit to read from the recording medium a recording block in which a linking loss area having a unit smaller than a unit of a recording block and having a predetermined size is disposed,
- wherein the recording block is used for data replacement for the purpose of replacement by logical overwrite (LOW) to update data recorded on the recording medium or replacement by defects occurred on the recording medium.
A recording method of recording data in an information recording medium, comprising:
- disposing a linking loss area having a unit smaller than a unit of a recording block and having a predetermined size in the recording block used for data replacement for the purpose of replacement by logical overwrite (LOW) to update data recorded in the recording medium or replacement by defects occurred on the recording medium;
- and
- recording the recording block on the recording medium.
A reproducing method for reproducing data from an information recording medium, comprising:
- reading, from the recording medium, a recording block in which a linking loss area having a unit smaller than a unit of the recording block and having a predetermined size is disposed, wherein the recording block is recorded for data replacement for the purpose of replacement by logical overwrite to update data recorded on the recording medium or replacement by defects occurred on the recording medium;
- and
- reproducing the read recording block.
The reproducing method according to claim 31, wherein, when the information indicating the linking loss area is extracted from the recording block, the information is extracted from a sector ID field of a second sector of the recording block.
An information storage medium comprising:
- a data area for recording data in blocks;
- and
- a linking loss area having a predetermined size disposed in a recording block used for data replacement by logical overwrite (LOW) to update data recorded in the data area;
- wherein a replacement entry recorded in the data area includes information indicating whether data replacement is performed by units of blocks or units of sectors within each block, information on original sectors within each block to be replaced, and information on replacement sectors to replace the original sectors.
