ABSTRACT:
A method of generating data sector pulse in a magnetic disk drive includes the steps of servo-writing a bit of index pattern information corresponding to each servo sector in an index area of a servo area on the magnetic disk by a predetermined rule, mapping a data sector pulse timing value with respect to a representative frame of each zone in an inside storage by changing the frame number of relevant zone according to the characteristic of each zone, and reading a sector pulse timing value with respect to a predetermined sector of a predetermined track from the inside storage by deciphering the index pattern information read from the track according to the rule and loading the read result in a gate array for generating the data sector pulse.
