Self-cleaning recording heads based on actuator seek profile

摘要

Cleaning a recording head slider in-drive during operation is accomplished by periodically performing a series of full stroke seek operations, whereby liquid contaminants that may have migrated to the head slider are flung from the slider and liquid from the disk surface may be adsorbed onto the slider for removal by way of flinging. Consequently, head-disk spacing may be stabilized and data write operations improved. Furthermore, the series of full stroke seek operations may be performed at predetermined intervals, and for a predetermined period of time. However, the series may be interrupted by a client request, and continued thereafter, so as not to affect the operational status of the recording system.

主权项

1. A method of cleaning a recording head slider comprising:
periodically performing a series of full stroke seek operations as quickly as operationally capable, including performing an inner diameter to outer diameter seek operation as quickly as operationally capable and performing a following outer diameter to inner diameter seek operation at a speed less than what is operationally capable.
