Abstract
A system for adapting head switching sequence in a disc drive includes a method of measuring the time duration for a head switch operation and the time duration of a track switch operation. The system compares the two time durations to determine whether head switching or track switching should be utilized within a zone of tracks on the surface of the data disc. Track switch time durations and head switch time durations may be averaged within a zone and the averages compared to determine whether to use head switching or track switching.
