Abstract: Methods, data storage devices, and computer-readable media for setting the flying height of a recording head are disclosed. A method may set a value of a control parameter of the recording head to force a predetermined location of the recording head to be a touchdown location. The method may involve incrementally moving the recording head toward a surface of a recording media, and, using a temperature sensor of the recording head, detecting an onset of touchdown at the touchdown location as the recording head is incrementally moving toward the surface of the recording media. The method may set the fly-height control power by backing off from an initial fly-height control power value, which may be a sum of a power level at which the onset of touchdown at the touchdown location was detected and a power corresponding to the value of the control parameter.

Abstract: Various illustrative aspects are directed to a data storage device, comprising one or more disks; an actuator mechanism configured to position a selected head among one or more heads proximate to a corresponding disk surface among the one or more disks, wherein the selected head comprises a magnetic write element and a laser generating component; and one or more processing devices. The one or more processing devices are configured to measure a magnetic saturation responsiveness of the corresponding disk surface to heat-assisted write operations using a range of values of write laser current applied to the laser generating component. The one or more processing devices are further configured to calibrate a nominal write laser current of the selected head for the corresponding disk surface based on the measured magnetic saturation responsiveness of the corresponding disk surface.

Abstract: An apparatus for containing a portion of a vehicle battery assembly incudes a tray. The tray is configured to receive the portion of the vehicle battery assembly. The tray defines a floor, a front wall, a rear wall, and a pair of sidewalls extending from the front wall to the rear wall. The tray includes a first steel material and a second steel material. The first steel material is joined with the second steel material to form a single contiguous part. The first steel material defines a substantial majority of the floor. The second steel material is disposed at two or more corners of the tray.

Abstract: A method of RAID migration comprising reading first and second blocks from a first RAID array. Said first blocks are written to a second RAID array within a first write cycle. Said second blocks are read simultaneously with a portion of said first write cycle in a pipelined fashion. In a first embodiment, pipelining increases the speed of RAID migration from a one-disk stripe array to a two-disk mirror array. In a second embodiment, pipelining and the use of duplicate blocks increases the speed of RAID migration from a two-disk mirror array to a three-disk RAID 5 array. In a third embodiment, pipelining and the use of duplicate blocks increases the speed of RAID migration from a three-disk RAID 5 array to a four-disk RAID 5 array.

Abstract: A method for providing a customizable reward service may include monitoring user activity associated with a web site relative to an operator defined lexicon of activities, comparing user activity to conditional rules defining multidimensional behaviors and corresponding rewards associated with satisfaction of the conditional rules, and determining whether to generate a reward from an operator defined lexicon of rewards based on satisfaction of the conditional rules. A corresponding apparatus is also provided.
