Information record carrier

Abstract

Abstract PURPOSE:To obtain accurate tracking correction signal when an arbitrary track signal is selected, by composing tracking tracks having provided with specific code signals at both side of signal track of a video disc. CONSTITUTION:A signal track 35 having recorded one frame of TV signal in one rotation is provided on a record carrier 34, and a tracking track 36 is disposed adjacently. In a vertical synchronizing signal region 37, the signal frequency recorded in the track 36 changes from the region 37 as the region 37 a boundary, and, for instance, 700 kHz signal is recorded in the dotted line region and 500 kHz signal in the dot-dash line region. In the track 35, address regions 38-1, 38-2, 38-3 ... are provided in part of the region 37, and address numbers ''1'', ''2'', ''3'', ... are stored successively in the corresponding address resions from the outer circumference towards the inner circumference.
