Abstract
Systems and methods for detecting a disk sync mark are provided. The systems and methods for detecting the disk sync mark rely on a detecting the disk sync mark on at least one timing interval. A window of data read bits from a particular disk sector are examined to determine whether they match the disk sync mark. The disk sync mark may be differentiated from expected versions of the disk sync mark using a calculated set of thresholds.
