Abstract

PURPOSE:To improve the durability of a magnetic disk by making the surface layer of a magnetic recording layer into the oxide layer, a nitride layer or an oxide film and executing the recording and reproducing while a magnetic head is brought into contact with a magnetic disk surface, with the innermost circumferential cylinder of the magnetic disk. CONSTITUTION:A magnetic disk 1 is rotated and driven in the direction of an arrow (a), a magnetic head 2 is supported by a gimbal type supporting device 3, driven and positioned in the direction of an arrow b1 or b2 on a rotation diameter O1 by a positioning device 4, and thus, the magnetic recording and reproducing are executed by prescribed cylinders T1-Tn. Since at least by an innermost circumferential cylinder T1, the recording and reproducing are executed while the magnetic head 2 is brought into contact with the surface of the magnetic disk 1, the spacing loss is reduced and the excellent recording and reproducing characteristic and the recording density characteristic are obtained. Since the surface layer of the magnetic recording layer is constituted of an oxide layer with a high hardness and a nitride layer, etc., the damage due to the contact of the magnetic disk 1 and the magnetic head 2 is minimized and the durability is improved.
