  • Adjusting a fly-height in hard disk drives
    Patent number: 7643240
    Abstract: A method for increasing reliability of a hard disk drive (HDD) is disclosed. One of a plurality of magnetic read/write heads in a hard disk drive (HDD) is determined to be disabled, and a fly-height associated with the disabled read/write head is increased with respect to a fly-height associated with the plurality of read/write heads.

  • Enabling intermittent contact recording on-demand
    Patent number: 7489466
    Abstract: One embodiment in accordance with the invention is a method that comprises determining if a slider of a data storage device is to perform a read or write operation with a disk of the data storage device. If the slider is to perform the read or write operation, the slider is set at a grazing contact with the disk for a predefined time frame to perform the read or write operation. The predefined time frame is approximately how long the slider can be in grazing contact with the disk without experiencing any substantial instability. After the predefined time frame expires, the slider is caused to move out of contact with the disk.
