Abstract: 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.

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.

Abstract: The disclosure is directed to a method for creating a remanence magnetization on a magnetic tape medium. The magnetic tape is first substantially demagnetized, e.g., erased, by an erasure unit having multiple magnetic elements of alternating polarity. The erased magnetic tape is then passed by a bias magnet that creates a remanence magnetization on the magnetic tape.

The bias magnet may be housed within the erasure unit or within a bias unit, and the distance between the bias magnet and the tape path of the magnetic tape may be adjustable to create the desired remanence magnetization on the magnetic tape. The remanence magnetization created on the magnetic tape may be greater than 20 percent to reduce defects in the servo pattern written to the magnetic tape.

Abstract: Embodiments of a computer system that includes a vibration-cancelling mode, and a related method and computer-program product (e.g., software) for use with the computer system, are described. During operation, a processor monitors operations in the computer system, and may select either the vibration-cancelling mode or an inactive mode based on the monitored operations.
