Optical recording medium having a plurality of sectors separated by sync signals

An optical disc, comprising:

• at least one track irradiated with light to record data thereon and to reproduce data recorded thereon,
• said track being divided into a plurality of clusters as units of data recorded or reproduced,
• each of said clusters being divided into a data area and a link area between data areas, and
• each of the data area and the link area being formed of unit frames separated by a sync signal;
• wherein said link area is formed of at least one frame, said link area having at least:
• a section for absorbing jitter;
• a section for absorbing a start position of said cluster;
• a section in which data for pulling in the sync signal is recorded;
• a section in which data indicating an address position is recorded;
• a section in which addresses of said track and said cluster are recorded;
• a section in which an error-detecting code is recorded;
• and
• a section in which data corresponding to security information is recorded.

• wherein said link area is formed of at least one frame, said link area having at least:
• a 2-byte postbuffer area for absorbing jitter;
• a 2-byte prebuffer area for absorbing a start position of said cluster;
• a 64-byte VFO area in which data for pulling in the sync signal is recorded;
• a 2-byte area in which data indicating an address position is recorded;
• a 4-byte area in which addresses of said track and said cluster are recorded;
• a 2-byte error-detection code area in which an error-detecting code is recorded;
• and
• a 4-byte security control area in which data corresponding to security information is recorded.
