Abstract

PURPOSE: To increase the efficiency of unit, by locating n sets of the alignment servo heads to the alignment servo track zone on the servo arm possible for proximity toward radial direction of magnetic disc in specified intervals.
CONSTITUTION: A plurality of disc shape magnetic discs 21, 22 are borne on the rotating spindle 20, and on the lower surface 23 of the disc 21, the inside read/write track zone 28 in cooperation with the moving type read/write magnetic heads 32, 31 held with the arm 26 and moving near radially the disc 21 with the carriage 25, and the external read/write track zone 27 are formed. The width of the servo zone 39 is 1/n (where; n is the number of servo heads) of the width l of the inside or outside read/write track zone 28, 27, and the gap between the servo heads 38, 37 is also l/n. Thus, the width of the alignment servo track zone can be reduced, then the efficiency of the magnetic disc memory unit can be increased remarkably.
