ABSTRACT:
A data recording magnetic disc apparatus having a plurality of recording surfaces formed on one or more discs has a single servo sector containing servo data for transducer position control provided on each recording surface, the servo sectors of respective surfaces being disposed at respectively different angular positions. Servo data obtained from all of the servo sectors is employed for transducer position control with respect to track center lines, the control including correction for the effects of eccentric rotation of the discs. Accurate head position control is achieved for high data density recording, with a minimum region of each recording track being occupied by servo data.
