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 a bit sequence associated with Gray codes and delays indications of the bit sequence detection to handle phase shifts. The detector generates a Gray code detection signal in response to the delayed indications. The control circuitry processes the Gray code in response to the Gray code detection signal.
