An optical disc (11 to 18) having sectors (3) each having a sector ID further comprises: a first area (4) having a first set of sectors (313-315) sequentially arranged on the disc (11 to 18) according to their respective IDs, a second area (5) having a second set of sectors (316-318) sequentially arranged on the disc (11 to 18) according to their respective IDs, the second area (5) being located after the first area (4) in respect of a disc scan direction (B) and having at least one sector ID which duplicates that of a sector in the first set of sectors, a start sector (33) located before the first area (4), and navigation data indicating to an optical disc reader, after having read the start sector (33), to displace its pickup reader device to a first target sector (316, 317, 352) having a sector ID of one of the sectors of the second area (5) or of a sector located after the second area (5), wherein the number of sectors between the start sector (33) and the first target sector is chosen such that the optical disc reader jumps from the start sector (33) to the first target sector using a cross track mode.
Optical disc (11 to 18) having sectors (3) each having a sector ID, the optical disc further comprising:
Optical disc (11 to 15) according to any one of the preceding claims, wherein a seventh area (12) is provided after the second area (5), and/or an eighth area (13) is provided after the fifth area (8), the seventh area (12) comprising at least one sector having a sector ID which duplicates that of a sector in the second set of sectors, the eighth area (13) comprising at least one sector having a sector ID which duplicates one of the fourth set of sectors.
Optical disc (11 to 15) according to any one of the preceding claims, wherein the numbers of sectors of at least one of the first, second, fourth, fifth, seventh and eighth areas (4, 5, 7, 8, 12, 13) differ from each other.
Optical disc (11 to 18) according to any one of the preceding claims, wherein the data stored within the first, fourth, seventh and eighth area (4, 5, 7, 8, 12, 13) causes an optical disc reader to terminate the reading process of the disc or to refuse to read specific data from the disc or to output distorted/advertising content.
Optical disc (11 to 18) according to any one of the preceding claims, wherein the data stored within the first to eighth area or within a part(s) is data which does not imply any significant reduction of the perceptable quality of the optical disc content for the consumer of the disc due to jumps of the optical pick up device caused by the first navigation data and/or the second navigation data and/or the third navigation data.
Optical disc (11 to 18) according to any one of the preceding claims, wherein the data stored within the first to eighth areas or within a part(s) is part of a VOB file of a DVD-Video.
Optical disc (11 to 18) according to any one of the preceding claims, wherein the optical disc is a CD-ROM, a CD-Extra, a SVCD, a SACD™, a DVD-ROM, a DVD-Video, a DVD-Audio, a PS2™-DVD, a UMD™, a HD-DVD, a Blu-ray disc or the like.
Optical disc (11 to 18) according to any one of the preceding claims, wherein the sectors of the optical disc are grouped into content cells, each content cell comprising at least one sector, wherein each of the first to eighth area comprises at least one content cell.
Optical disc (11 to 18) according to any one of the preceding claims, wherein the optical disc is a DVD-Video, and wherein buttons are activated automatically, thereby executing corresponding button commands.
Optical disc (11 to 18) having sectors (3) each having a sector ID, the optical disc further comprising:
Master disk for storing a copy protected master image, said master disk being suitable for transferring said copy protected master image onto a plurality of optical discs (11 to 18), the optical disc having sectors (3) each having a sector ID and further comprising:
Data signal representing information suitable for transfer to an optical disc (11 to 18) having sectors (3) each having a sector ID, the optical disc further comprising:
