Design of Servo Code and Synchronous Clock Writing Scheme on a High Capacity Disk Drive

A disk drive servo code and synchronous writing scheme is described in this paper. The encoding and decoding of the servo code; the writing and detecting of the synchronous clock writing can be realized in this system. In this paper, a synchronous clock writing with variable frequency method is discussed. The mathematical analysis of the variable frequency clock writing, the system design, and the writing and detecting of the servo code are presented.
