Head tracking system.

摘要

When a disk (76) on which signals are recorded in a number of separate tracks (T) is inserted into reproducing apparatus, reproduction signals from a head (13) are first obtained and tracking is performed for each track (T) to determine the position of the head (13) that gives the strongest reproduced signal from each such track (T). The tracking positions that respectively give the strongest signals from the several tracks (T) are stored in a memory (35). When it is later desired to reproduce signals from a particular track (T), the head (13) is positioned on the basis of the content of the memory.
