Abstract

PURPOSE:To prevent the positioning error of a servo head by adding track address information to head positioning information stored on disks in an interchangeable disk pack and fixed disk pack. CONSTITUTION:Servo head 11, when positioned on odd-address track 26 and even- address track 27 among positioning tracks 26-29 in track positioning information region 18, reproduces encoded patterns in passing through address information region 22 to confirm track addresses. In address information region 20, track addresses are stored. Servo information regions 18 and 19 and region 20 are equal in track interval and region 20 shifts from regions 18 and 19 by a half track width. As the track at address (x) in a fixed disk pack is selected and then that at address (y) in an interchangeable disk pack is selected, a one-track extra movement is detected from information in region 20 and a one-track return is made.
