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 dummy data, and to methods and apparatuses for forming, recording, and reproducing the recording medium.
Claims27
A 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 followed by fixed data which is non-scrambled, and including scrambled data produced by scrambling data with address information associated with a preceding data section.
The recording medium of clam 1, wherein each frame sync consists of 30 channel bits and each linking frame consists of 1932 channel bits.
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;
- and
- 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 which is non-scrambled, and including scrambled data,
- wherein the scrambled data was scrambled with address information associated with a preceding data section.
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 which is non-scrambled and including scrambled data,
- wherein the scrambled data was scrambled with address information associated with a preceding data section.
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;
- a scrambler circuit configured to scramble data with address information associated with a preceding data section;
- 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 which is non-scrambled and including the scrambled data.
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;
- a scrambler circuit configured to scramble data with address information associated with a preceding data section;
- and
- a controller configured to control the optical pickup to record a frame sync in the head position of each linking frame, non-scrambled fixed data following the frame sync and the scrambled data during recording the data.
