This invention describes the use of a counter and digital logic to provide a timing pulse needed to decode Gray code position information on the tracks of a rotating disk storage media when the timing pulse is missing because the head of the disk drive is straddling two tracks as the Gray code passes beneath the head. The logic synchronizes the timer to provide a pulse at precisely the right time if and only if a pulse originated by the Gray code is missing.
