る。Conventionally, magnetic disk devices using this type of magnetic disk medium have a contact star l when starting and stopping the device.
A floating method using a stop (hereinafter referred to as CSS) is adopted, and as shown in Fig. 2, the inner circumferential side is used as a CSS area and the outer circumferential side is used as a data area. 1. In magnetic disk media, in order to improve durability, a magnetic film layer 2 is formed on both sides of a non-magnetic support 10, a lubricant is applied on this magnetic film layer 2, and a predetermined constant film thickness is applied. The lubricating film layer 3 is in full form.

。In the conventional magnetic disk medium described above, the thickness of the lubricating film layer 3 is constant over the entire surface, and if the lubricating film layer 3 is thick, the magnetic head and the magnetic disk medium surface will stick together when the magnetic disk device starts up. On the other hand, if the thickness of the lubricating film layer 3 is made thinner to prevent this adsorption, C
The result is that the durability against SS operation is reduced.

避領域を設けたものである。In order to solve these problems, the present invention is used in a contact start/stop type magnetic disk device, in which a magnetic film layer and a lubricant film layer having a predetermined film thickness are laminated on a non-magnetic material. In the magnetic disk medium according to the present invention, a retraction area made of a lubricant film layer with a thinner film thickness than the above-mentioned lubricant film layer is provided on the inner peripheral side of the CSS area and data area of the magnetic disk medium.

る磁気ディスク媒体面との吸着が女〈なる。In the present invention, by moving the magnetic head to the retraction area of the thin lubricating film layer, the attraction to the magnetic disk medium surface that occurs when the magnetic head starts flying is reduced.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

一体的に成膜されて退避領域が形成されている。FIG. 1 is a sectional view showing an embodiment of the magnetic disk medium of the present invention. As shown in the figure, magnetic films 2 are formed on both sides of the non-magnetic support 1. A lubricant is applied to these magnetic films 2, and a predetermined film thickness is applied to the data area and CSS area. A lubricant film layer 3a is formed, and a lubricant film layer 3b, which is thinner than the lubricant film layer 3a, is integrally formed inside the CSS region to form a retraction region.

させることができるという効果がある。As explained above, the present invention provides CS of a magnetic disk medium.
By providing an evacuation area for the magnetic head that has a lubricant film layer that is thinner than the S area and the data area, the problem that occurs when the magnetic head starts flying can be moved by moving the magnetic head just before the magnetic disk drive stops. It is possible to eliminate adhesion to the magnetic disk medium surface. Another advantage is that the thickness of the lubricant film layer in the CSS area and data area can be increased, and durability can be improved.
