Method of cleaning disk drive recording head

摘要

A magnetic disk for self-cleaning a disk drive recording head communicating with a surface of the magnetic disk. The magnetic disk contains an abrasive cleaning zone of a designated width located at an outer periphery on the surface of the magnetic disk. When a recording head periodically passes over and contacts the abrasive surface of the cleaning zone, particles or other contaminants adhered to the recording head are mechanically removed by the relative motion between the rotating disk and the recording head. The recording head may then be returned to a landing zone on the disk, if the cleaning takes place at the end of a stop cycle, or the recording head may be returned to a track in a data zone on the disk if the cleaning takes place during normal disk drive operations.
