Abstract
The present invention discloses an apparatus and method for generating clock signals recorded along a track of a rotating disk storage system, wherein the recorded clock signals have count closure and/or phase closure. In one aspect, a clock generation circuit records a temporary clock track on a disk, senses information about the temporary clock track, and uses the sensed information to determine parameters relating to a frequency for a clock signal that will provide count closure and/or phase closure when the clock signal is written along a track on the disk.
