Data storage device compensating for head/tape wear
A data storage device is disclosed comprising at least one head configured to access a magnetic tape. A plurality of access commands are stored in a command queue, and a wear value is generated for each access command in the command queue, wherein the wear value represents a level of wear on the head or magnetic tape associated with executing the access command. An execution order for the access commands is generated based on the wear values, and at least one of the access commands is executed based on the execution order.

HIGH TEMPERATURE LUBRICANTS FOR MAGNETIC MEDIA
High temperature lubricants for magnetic media are provided. One such lubricant includes fluoroalkyl, fluoroalkenyl, perfluoroalkyl, or perfluoroalkyl ether segments, anchoring functional groups engageable with a protective overcoat of a magnetic recording media, and cyclic functional groups. The lubricants can be used in conjunction with a magnetic recording medium and/or a magnetic data storage system.
LOW PROFILE LUBRICANTS FOR DATA STORAGE DEVICES
Low-profile thermally stable lubricants for data storage devices are provided based on multi-dentate molecular designs. One such lubricant comprises perfluoroalkyl ether segments, a divalent linking segment, and anchoring functional groups attachable to, or engageable with, a protective overcoat of a magnetic recording medium. The lubricants can be used in conjunction with a magnetic recording medium and/or a magnetic data storage system.
Microwave assisted magnetic recording head slider and lapping method thereof
A lapping method of a MAMR head slider includes a first lapping process: controlling the lapping plate to spin at a first speed, and controlling the MAMR head slider to move at a first moving speed, and applying a first force to the MAMR head slider; and a second lapping process: controlling the lapping plate to spin at a second speed that is lower than the first speed, and controlling the MAMR head slider to move at a second moving speed that is lower than the first moving speed, and applying a second force that is lower than the first force to the MAMR head slider; and the second lapping process includes a final lapping process section, and the second force in the final lapping process being zero. In such a way, lapping marks on the ABS are reduced to improve the roughness and the reliability.

Protecting a sensitive device from corrosion
A method in one embodiment includes fabricating a tape having an applicator portion for applying an organic coating to a magnetic head for reducing exposure of the head to oxidation promoting materials. The method also includes applying the organic coating to the applicator portion of the tape, the organic coating being for coating a tape bearing surface of the magnetic head with the organic coating upon the applicator portion being run over the tape bearing surface of the magnetic head. The method further includes applying a lubricant to a data portion of the tape.
