Write once recording medium, recording device and recording method for write one recording medium, and reproduction device and reproduction method for write once recording medium

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;
• (ii) a control information recording area to record therein information for controlling an operation of recording and/or reading in said data area, said control information recording area including a definite defect management area to record therein defect management information of said data area;
• and (iii) a temporary defect management area to temporarily record therein the defect management information of said data area, said temporary defect management area being located between said control information recording area and said data area,
• said recording apparatus comprising:
• a first recording device for recording the record data into said data area;
• a memory device for storing therein the defect management information;
• a second recording device for recording the defect management information stored in said memory device, into said temporary defect management area;
• and
• a third recording device for recording the defect management information stored in said memory device, into said definite defect management area.

A reproducing apparatus for reproducing record data recorded on a write-once-type recording medium comprising:

• (i) a data area to record therein the record data;
• (ii) a control information recording area to record therein information for controlling an operation of recording and/or reading in said data area, said control information recording area including a definite defect management area to record therein defect management information of said data area;
• and (iii) a temporary defect management area to temporarily record therein the defect management information of said data area, said temporary defect management area being located between said control information recording area and said data area,
• said reproducing apparatus comprising:
• a memory device;
• a first reading device for reading the defect management information recorded in said temporary defect management area and storing the read defect management information into said memory device;
• and
• a reproducing device for reproducing the record data recorded in said data area on the basis of the defect management information stored in said memory device.

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;
• (ii) a control information recording area to record therein information for controlling an operation of recording and/or reading in said data area, said control information recording area including a definite defect management area to record therein defect management information of said data area;
• and (iii) a temporary defect management area to temporarily record therein the defect management information of said data area, said temporary defect management area being located between said control information recording area and said data area,
• said recording method comprising:
• a first recording process of recording the record data into said data area;
• a defect-management-information generating process of generating or updating the defect management information;
• a second recording process of recording the defect management information generated or updated in said defect-management information generating process, into said temporary defect management area;
• a finalize-command process of giving a command for indicating to finalize said recording medium;
• and
• a third recording process of recording the defect management information generated or updated in said defect-management-information generating process, into said definite defect management area in case that the command for indicating to finalize is given in said finalize-command process.

A reproducing method of reproducing record data recorded on a write-once-type recording medium comprising:

• (i) a data area to record therein the record data;
• (ii) a control information recording area to record therein information for controlling an operation of recording and/or reading in said data area, said control information recording area including a definite defect management area to record therein defect management information of said data area;
• and (iii) a temporary defect management area to temporarily record therein the defect management information of said data area, said temporary defect management area being located between said control information recording area and said data area, said reproducing method comprising:
• a detecting process of detecting whether or not said recording medium is already finalized;
• a first reading process of reading the defect management information recorded in said temporary defect management area and storing the read defect management information into said memory device in case that it is detected that said write-once-type recording medium is not finalized;
• a second reading process of reading the defect management information recorded in said definite defect management area and storing the read defect management information into said memory device in case that it is detected that said write-once-type recording medium is already finalized;
• and
• a reproducing process of reproducing the record data recorded in said data area on the basis of the defect management information stored in said memory device.
