Abstract
There is provided a disk-type recording medium, a recording apparatus, a recording method, a reproducing apparatus, and a reproducing method, which are capable of recording, for example, data with high density and reproducing data recorded with high density robustly. In the disk-type recording medium, synchronization patterns for synchronization are recorded in two adjacent tracks with a shift in a track direction so that positions in the track direction do not overlap. The present technology can be applied to, for example, optical discs, other disk-type recording mediums, and the like.
Claims20
A disk-type recording medium, comprising:
- synchronization patterns for synchronization being recorded in two adjacent tracks with a shift in a track direction so that positions in the track direction do not overlap,
- wherein the two adjacent tracks are a land and a groove, and
- wherein an interval of two synchronization patterns arranged in the track direction is unique.
(canceled)
(canceled)
A recording apparatus, comprising:
- a recording unit that records synchronization patterns for synchronization in two adjacent tracks of a disk-type recording medium with a shift in a track direction so that positions in the track direction do not overlap,
- wherein the recording unit records the synchronization patterns so that an interval of two synchronization patterns arranged in the track direction is unique.
(canceled)
A recording method, comprising:
- recording synchronization patterns for synchronization in two adjacent tracks of a disk-type recording medium with a shift in a track direction so that positions in the track direction do not overlap,
- wherein the recording unit records the synchronization patterns so that an interval of two synchronization patterns arranged in the track direction is unique.
A reproducing apparatus, comprising:
- a reproducing unit that reproduces a reproduction signal from a disk-type recording medium in which synchronization patterns for synchronization are recorded in two adjacent tracks with a shift in a track direction so that positions in the track direction do not overlap, the synchronization patterns being recorded so that an interval of two synchronization patterns arranged in the track direction is unique;
- and
- a detecting unit that detects the synchronization patterns from the reproduction signal and specifies the positions of the synchronization patterns in accordance with the interval of the two synchronization patterns.
(canceled)
A reproducing method, comprising:
- reproducing a reproduction signal from a disk-type recording medium in which synchronization patterns for synchronization are recorded in two adjacent tracks with a shift in a track direction so that positions in the track direction do not overlap, the synchronization patterns being recorded so that an interval of two synchronization patterns arranged in the track direction is unique;
- and
- detecting the synchronization patterns from the reproduction signal and specifying the positions of the synchronization patterns in accordance with the interval of the two synchronization patterns.
