Abstract

PURPOSE:To make data tracks high density without using a complex circuit by detecting a servo pattern recorded on a magnetic disk by a means other than a magnetic recording means and executing accurate tracking servo. CONSTITUTION:The magnetic disk 1 has the servo pattern (SP) for tracking servo concentrically or spirally formed by a means other than a magnetic recording means and two collating burst signals V1, V2 magnetically recorded in an area other than a data area A0 so as to be shifted from each other in the diameter direction on the basis of the SP. A magnetic head 4 for recording/ reproducing a data signal is provided with a sensor 2 for detecting the SP at a position separated by a prescribed distance, and when the SP is out from the detecting range, on-track is immediately executed by a tracking control circuit 4 for comparing the levels of the signals V1, V2 and detecting and collating the quantity of off-track, a head actuator driving circuit 11 and a head actuator 8. Thereby, the interval between tracks can be shortened and high density can be attained.
