The cleaning of disk 10 is accomplished by means of a water stream 12 that is directed from nozzle 14 at an acute angle with respect to the upper surface of disk 10. Disk 10 comprises an aluminum substrate disk 16 having a magnetic coating 18 on its upper surface and a lubricant layer 20 on magnetic coating 18. Disk 10 has a central opening 22 through it for receiving a drive hub of any suitable type, and disk 10 is drivingly rotated by the hub about its center line 24. Current recording component technology for rigid disks, such as disk 10, necessitates that the recording head fly as close to the magnetic media as possible. These distances are exceedingly small in comparison with the size of ambient particulate contamination that can exist on a disk surface.
