Abstract
A method of write frequency management for writing recorded data to an optical rewritable storage medium. The optical rewritable storage medium comprises a data area and a count area. The data area comprises multiple data units, the count area comprises multiple values, and each value represents a write frequency corresponding to one of the data units. The method receives a data write instruction comprising a write address range and the recorded data, writes the recorded data to the data units corresponding to the write address range, and updates the values corresponding to the write address range.
Claims20
A method of write frequency management loaded and executed by a processing unit in an optical read/write apparatus, writing recorded data to an optical rewritable storage medium comprising a data area and a count area, the data area comprising a plurality of data units, the count area comprising a plurality of values, each value representing a write frequency corresponding to one of the data units, the method comprising the steps of:
- receiving a data write instruction comprising a write address range and the recorded data;
- writing the recorded data to the data units corresponding to the write address range;
- and
- updating the values corresponding to the write address range.
A machine-readable storage medium for storing a computer program which, when executed, performs a method of write frequency management, writing recorded data to an optical rewritable storage medium comprising a data area and a count area, the data area comprising a plurality of data units, the count area comprising a plurality of values, each value representing a write frequency corresponding to one of the data units, the method comprising the steps of:
- receiving a data write instruction comprising a write address range and the recorded data;
- writing the recorded data to the data units corresponding to the write address range;
- and
- updating the values corresponding to the write address range.
An apparatus for writing recorded data to an optical rewritable storage medium comprising a data area and a count area, the data area comprising a plurality of data units, the count area comprising a plurality of values, each value representing a write frequency corresponding to one of the data units, the apparatus comprising:
- a read/write component;
- and
- a processing unit,
- wherein the processing unit receives a data write instruction comprising a write address range and the recorded data, directs the read/write component to write the recorded data to the data units corresponding to the write address range, and directs the read/write component to update the values corresponding to the write address range.
An optical rewritable storage medium comprising:
- a data area comprising a plurality of data units;
- and
- a lead-out area comprising a count area, the count area comprising a plurality of values, each value representing a write frequency corresponding to one of the data units.
