Abstract
A disk drive system is disclosed that includes a disk device coupled to control circuitry. The control circuitry includes a read channel with a detector that detects servo mark sub-patterns and correlates the detected servo mark sub-patterns to detect a servo mark. The detector includes matched filters to detect the sub-patterns.
