Abstract
Provided are recording media, recording/reproducing apparatuses, and recording methods for use in long-term data retention. Recording medium information may be copied and stored in a new information zone in a data area. Accordingly, if medium recognition of a lead-in area and/or a lead-out area fails, a recording medium may be recognized using the data recorded in the new information zone.
Claims20
A recording medium comprising a lead-in area, a data area, and a lead-out area,
- wherein the data area comprises:
- a non-recording zone allocated adjacent to at least one of the lead-in area and the lead-out area;
- and
- an information zone allocated at an inner side of the non-recording zone and toward a center of the data area, the information zone for recording information about the recording medium.
1 more element
A recording/reproducing apparatus comprising:
- an optical pickup configured to irradiate light onto a recording medium to record data thereon;
- a memory configured to store information about ranges of a valid data area and a new information zone of a recording medium, which are obtained in advance by performing a test;
- and
- a control unit configured to allocate a non-recording zone adjacent to at least one of a lead-in area and a lead-out area in a data area of a target recording medium, to allocate an information zone at an inner side of the non-recording zone toward a center of the data area, based on the information stored in the memory, and to control recording medium information to be recorded in the information zone.
1 more element
A recording method comprising:
- allocating a non-recording zone adjacent to at least one of a lead-in area and a lead-out area in a data area of a target recording medium;
- allocating an information zone at an inner side of the non-recording zone toward a center of the data area, based on ranges of a valid data area which are obtained in advance by performing a test and which is stored in a memory of the recording/reproducing apparatus;
- and
- recording information about the recording medium in the information zone.
