Abstract
A write-once-type recording medium (100) on which record data can be recorded only once, provided with: a data area (108) to record therein the record data; and a shared area (104, 105) to temporarily record therein evacuation data which is record data to be recorded or already recorded at a position of a defect in the data area and defect management information (120) including an evacuation source address of the evacuation data.
Claims16
A write-once-type recording medium comprising:
- a data area to record therein record data;
- and
- a shared area to record therein evacuation data which is record data to be recorded at a position of a defect in said data area and defect management information including an evacuation source address of the evacuation data, together.
A recording apparatus for recording record data onto a write-once-type recording medium comprising:
- (i) a data area to record therein the record data;
- and (ii) a shared area to record therein evacuation data which is record data to be recorded at a position of a defect in said data area and defect management information including an evacuation source address of the evacuation data, together,
- said recording apparatus comprising:
- a first recording device for recording the record data into said data area;
- and
- a second recording device for recording the evacuation data and the defect management information into said shared area.
A recording method of recording record data onto a write-once-type recording medium comprising:
- (i) a data area to record therein the record data;
- and (ii) a shared area to record therein evacuation data which is record data to be recorded at a position of a defect in said data area and defect management information including an evacuation source address of the evacuation data, together,
- said recording method comprising:
- a first recording process of recording the record data into said data area;
- and
- a second recording process of recording the evacuation data and the defect management information into said shared area.
A reproducing apparatus for reproducing the record data recorded on a write-once-type recording medium comprising:
- a data area to record therein record data;
- and a shared area to record therein evacuation data which is record data to be recorded at a position of a defect in said data area and defect management information including an evacuation source address of the evacuation data, together,
- said reproducing apparatus comprising:
- a reading device for reading the defect management information recorded in said shared area;
- and
- a reproducing device for reproducing the record data recorded in said data area or the evacuation data recorded in said spare area, on the basis of the read defect management information.
A reproducing method of reproducing the record data recorded on a write-once-type recording medium comprising:
- a data area to record therein record data;
- and a shared area to record therein evacuation data which is record data to be recorded at a position of a defect in said data area and defect management information including an evacuation source address of the evacuation data, together,
- said reproducing method comprising:
- a reading process of reading the defect management information recorded in said shared area;
- and
- a reproducing process of reproducing the record data recorded in said data area or the evacuation data recorded in said spare area, on the basis of the read defect management information.
A computer program product for recording control in a computer-readable medium for tangibly embodying a program of instructions executable by a computer provided for a recording apparatus, said program making the computer function as at least one portion of a first recording device and a second recording device,
- said recording apparatus for recording record data onto a write-once-type recording medium comprising:
- (i) a data area to record therein the record data;
- and (ii) a shared area to record therein evacuation data which is record data to be recorded at a position of a defect in said data area and defect management information including an evacuation source address of the evacuation data, together,
- said recording apparatus comprising:
- said first recording device for recording the record data into said data area;
- and
- said second recording device for recording the evacuation data and the defect management information into said shared area.
A computer program product for reproduction control in a computer-readable medium for tangibly embodying a program of instructions executable by a computer provided for a reproducing apparatus, said program making the computer function as at least one portion of a reading device and a reproducing device,
- said reproducing apparatus for reproducing the record data recorded on a write-once-type recording medium comprising:
- a data area to record therein record data;
- and a shared area to record therein evacuation data which is record data to be recorded at a position of a defect in said data area and defect management information including an evacuation source address of the evacuation data, together,
- said reproducing apparatus comprising:
- said reading device for reading the defect management information recorded in said shared area;
- and
- said reproducing device for reproducing the record data recorded in said data area or the evacuation data recorded in said spare area, on the basis of the read defect management information.
A data structure comprising:
- a data area to record therein the record data;
- and
- a shared area to record therein evacuation data which is record data to be recorded at a position of a defect in said data area and defect management information including an evacuation source address of the evacuation data, together.
