摘要：A system of recording and/or reproducing information comprises: (1) A

magnetizable medium(10) of servo track(11-19) inside which there is servo signal shown inmagnetized pattern format by deeply recording; (2) A means(100) including a magnetichead device(20) having pick-up head(21); (3) Means(30) for moving magnetic head devicefollowing intersection direction(32) with servo track and relative to medium; (4)Actuator(40) for moving magnetic head device following intersection direction(32) withservo track and relative to medium; (5) A servo circuit(50) installed between readingmagnetic head and actuator, in which said circuit is adjusted to make reading magnetichead perform reading following the boundary between two adjacent servo tracks(13, 14)according to servo signal read from track; (6) Device adjusted to write information signalto information track(61, 65) on servo signal in servo track, having the feature that saiddevice includes control device(70) capable of writing information track(61-68) in

sequence, and in the sequence reading magnetic head will operate on either one of twonon-overwritten parts(62, 64) of medium, or either one of two overwritten parts of

medium.
