Abstract
An optical disc including: sectors each having a sector ID; a first area having a first set of sectors sequentially arranged on the disc according to their respective IDs; a second area having a second set of sectors sequentially arranged on the disc according to their respective IDs, the second area being located after the first area in respect of a disc scan direction, the second area including all information needed for playback of the entire disc and having at least one sector ID which duplicates that of a sector in the first set of sectors.
Claims21
An optical disc comprising:
- sectors each having a sector ID;
- a first area having a first set of sectors sequentially arranged on the disc according to their respective IDs;
- a second area having a second set of sectors sequentially arranged on the disc according to their respective IDs, the second area being located after the first area in respect of a disc scan direction, the second area including all information needed for playback of the entire disc and having at least one sector ID which duplicates that of a sector in the first set of sectors;
- a start sector located before the first area;
- and
- navigation data, included in the start sector, which instructs an optical disc reader, after the optical disc reader has read the start sector, to displace a pickup reader device to a first target sector having a sector ID of one of the sectors of the second area or of a sector located after the second area, wherein the number of sectors between the start sector and the first target sector is chosen so that the pickup reader device jumps from the start sector to the first target sector using a cross track mode.

An optical disc comprising:
- sectors each having a sector ID;
- a first area having a first set of sectors sequentially arranged on the disc according to their respective IDs;
- and
- a second area having a second set of sectors sequentially arranged on the disc according to their respective IDs, the second area being located after the first area in respect of a disc scan direction, the second area including all information needed for playback of the entire disc and having at least one sector ID which duplicates that of a sector in the first set of sectors;
- and
- a start sector located before the first area,
- wherein data is arranged on the optical disc such that after an optical disc reader has read the start sector, data reading is continued at a first target sector having a sector ID of one of the sectors of the second area or of a sector located after the second area, a number of sectors between the start sector and the first target sector causes a read-out laser beam of the optical disc reader to jump from the start sector to the first target sector using a cross track mode.

A master disc comprising:
- a copy protected master image suitable for transfer to an optical disc that includes,
- sectors each having a sector ID,
- a first area having a first set of sectors sequentially arranged on the disc according to their respective IDs,
- a second area having a second set of sectors sequentially arranged on the disc according to their respective IDs, the second area being located after the first area in respect of a disc scan direction, the second area including all information needed for playback of the entire disc and having at least one sector ID which duplicates that of a sector in the first set of sectors,
- a start sector located before the first area, and
- navigation data, included in start sector, which instructs an optical disc reader, after the optical disc reader has read the start sector, to displace a pickup reader device to a first target sector having a sector ID of one of the sectors of the second area or of a sector located after the second area, wherein the number of sectors between the start sector and the first target sector is chosen so that the pickup reader device jumps from the start sector to the first target sector using a cross track mode.
