ABSTRACT:
Encoding and decoding of track address information stored on an optical disk is provided. The optical disk includes a number of tracks, each track being definable as having a plurality of position segments for storing track address information. Each of the position segments includes a single recording mark. The location of the recording mark in the position segment is indicative of the value of a digit that represents the encoded track address information. Preferably, the location of only one recording mark for a position segment changes between adjacent disk tracks. When decoding the track address information read from the optical disk, differential detection is utilized.
