Abstract

A method and apparatus for providing a dynamic fine track seeking operation that adaptively fine tunes the entrance criteria used to determine when the head is on track for the specific disc drive under actual operating conditions. The method and apparatus includes adaptively modifying entrance criteria individually for each head in a disc drive according to actual operating conditions with the use of stored entrance criteria for each head, an extra track proximity threshold and a successful entrance counter.
