Abstract
A method and apparatus for detecting sector servo information in a disk system, uses sector servo information with at least one auxiliary confirming code pattern provided in addition to conventionally-used sector mark, track address and servo position information. Generation of a group of timing signals to detect a selected portion of the sector servo information, is adjusted by detecting the auxiliary confirming code pattern so that the timing signal is synchronized with the selected portion of the sector servo information In another embodiment, synchronization is performed using a predetermined number which is loaded into a counter circuit when the auxiliary confirming code pattern is detected.
