TRACKING METHOD AND TRACK FORMAT BASED ON RADIAL CROSS-TALK FROM ADJACENT TRACKS

摘要

An optical recording medium having a number of adjacent tracks for storing digital optical information extending in a first direction. The tracks are separated by a pitch amount in a second direction and each track has a servo field comprising at least one synchronization mark (BM, CM) and at least one tracking mark (TM) in one of at least three positions on the track. The tracking marks (TM) of tracks adjacent in the second direction to a first track are in different positions from each other and from the position of the tracking mark on the first track. The tracking marks (TM) extend in the second direction to give rise to cross-talk from the tracking marks (TM) of adjacent tracks when the first track is being read.
