ABSTRACT:
Recording into and reproduction from the magnetic disc 3 is done a magnetic head installed on a head slider of which at least a portion is floated during the recording/reproduction. On the magnetic disc 3, there are formed a data zone 3a consisting of groove-like grooves 3a.sub.2 are formed along the recording track and lands 3a.sub.1 formed between the grooves 3a.sub.2 and on which an information signal is recorded, and a servo zone 3b to record control signals and consisting of grooves 3b.sub.2 and lands 3b.sub.1 corresponding to control signals including a servo signal and magnetized to have opposite polarities. In the servo zone 3b, the lands 3b.sub.1 are larger in area than the grooves 3b.sub.2. Such structure provides for a more stabilized fly height for the head slider.
