Abstract
A tracking miss control system for a disk player can be used in which small track misses purposely are not detected. The allowable range of the returning operation is increased with the frequency of the tracking miss. Thus, when the frequency of the tracking miss is high, track misses will be detected with a larger tolerance than when the frequency of the tracking miss is low.
