Abstract
A recording medium, such as a high-density and/or read-only recording medium including a data area including at least two data sections and a linking area to link neighboring data sections, the linking area including at least two frame sync signals, where values of the at least two frame sync signals maintain uniqueness, and to methods and apparatuses for forming, recording, and reproducing the recording medium.
Claims24
A non-transitory read-only recording medium, comprising:
- a data area including at least two data sections;
- and
- a linking area to link neighboring data sections, the linking area including two linking frames of the same size, each linking frame including a frame sync in the head position,
- wherein the two frame syncs of the linking area are selected from a frame sync set excluding frame syncs included in corresponding linking area of a writable recording medium, each of the two frame syncs being followed by fixed data wherein a frame in one of the data area and the linking area is identifiable based on a combination of a frame sync of the frame and a frame sync of a preceding frame.

An apparatus for reproducing data from a read-only recording medium, comprising:
- an optical pickup configured to reproduce data recorded on a data area of the read-only recording medium, the data area including at least two data sections;
- a controller configured to control the optical pickup to identify a linking area included in the read-only recording medium, the linking area linking neighboring data sections and including two linking frames of the same size, each linking frame including a frame sync in the head position followed by fixed data,
- wherein the two frame syncs of the linking area are selected from a frame sync set excluding frame syncs included in corresponding linking area of a writable recording medium wherein the controller is configured to control the optical pickup to identify a frame in one of the data area and the linking area based on a combination of a frame sync of the frame and a frame sync of a preceding frame.
A method for reproducing data from a read-only recording medium, comprising:
- identifying a linking area included in the recording medium, the linking area linking neighboring data sections included in a data area of the recording medium and including two linking frames of the same size, each linking frame including a frame sync in the head position followed by fixed data,
- wherein the two frame syncs of the linking area are selected from a frame sync set excluding frame syncs included in corresponding linking area of a writable recording medium wherein the identifying step identifies a frame in one of the data area and the linking area based on a combination of a frame sync of the frame and a frame sync of a preceding frame.
An apparatus for recording data on a recording medium, comprising:
- an optical pickup configured to record data on the recording medium, wherein the recording medium comprises a data area including at least two data sections and a linking area linking neighboring data sections;
- and
- a controller configured to control the optical pickup to record the linking area, the linking area including two linking frames of the same size, each linking frame including a frame sync in the head position followed by fixed data,
- wherein the two frame syncs of the linking area are selected from a frame sync set excluding frame syncs included in corresponding linking area of a writable recording medium wherein the controller is configured to control the optical pickup to identify a frame in one of the data area and the linking area based on a combination of a frame sync of the frame and a frame sync of a preceding frame.
1 more element
An apparatus for manufacturing a recording medium, comprising:
- an optical pickup configured to record data on the recording medium, wherein a data area including at least two data sections and a linking area including at least two linking frames of the same size and linking neighboring data sections are formed during recording the data;
- and
- a controller configured to control the optical pickup to record a frame sync in the head position of each linking frame and fixed data following the frame sync,
- wherein the two frame syncs of the linking area are selected from a frame sync set excluding frame syncs included in corresponding linking area of a writable recording medium are recorded wherein the controller is configured to control the optical pickup to identify a frame in one of the data area and the linking area based on a combination of a frame sync of the frame and a frame sync of a preceding frame.
