Appeal No. 2005-2584 Application No. 09/897,331 The Invention The invention relates to a record carrier, particularly an optically readable disk, which has information marks along tracks which exhibit first variations representing an information signal recorded on the carrier and second variations caused by variations associated with the information marks. The phase of the first variations is coupled to the phase of the second variations. See page 2 of appellants’ specification. The first variations are in the form of pits formed in a track on the disk, which are optically detectable, and the second variation are in the form of track undulation also known as wobble. See page 5 of appellants’ specification. The phase of the second variations is coupled to the phase of the first variations in that a predetermined number of wobbles corresponds to a predetermined number of channel bits represented by the first variation. Claim 4 is representative of the invention and is reproduced below: 4. A record carrier (1) having information marks along a track (11) thereof and exhibiting: first variations caused by existence and nonexistence of the information marks along the track, said first variations representing an information signal recorded on said record carrier, and second variations (W) caused by variations associated with the information marks; the phase of the second variations being coupled to the phase of the first variations. 2Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
