Title: Magnetic disk medium
Inventor: KUROIWA FUMIO
IPC: G11B5/82
Filed: 1989-10-03
Abstract: PURPOSE:To enable cleaning of a magnetic head with a disk medium by provid ing a nonmagnetic layer containing alumina fine powder and a binder on a supporting body to form a cleaning area. CONSTITUTION:A contact-start-stop (CSS) area 6 is provided on the inner circum ferential area of the recording area 5, and the cleaning area 7 is further pro vided on the inner circumferential area of the CSS area 6. The recording area 5 and CSS area 6 of the supporting body 1 are covered with a magnetic layer 3 and lubricating layer 4, while the cleaning area of the supporting body 1 is covered with a nonmagnetic layer 2 containing alumina powder dispersed in a binder. When the rotation speed of the disk decreases as low as <=200 cps just before a spindle motor stops, a magnetic head is moved from the CSS area 6 to the cleaning area 7 on the nonmagnetic layer 2 so that the rough surface due to alumina fine particles can scrape dust or foreign matter deposited on the magnetic head. Since the nonmagnetic layer is not covered with lubricat ing layer, removed dust or the like is thrown away by centrifugal force. Thus, cleaning of a magnetic head can be performed.
