  • Reducing the height of a defect associated with an air bearing surface
    Patent number: 8361284
    Abstract: A method for reducing the height of a defect associated with an air bearing surface of a hard disk drive slider is disclosed. The technology initially ion mills for a first period of time at a first angle relative to an air bearing surface of a disk drive slider to remove a first portion of the air bearing surface. Then the technology ion mills for a second period of time at a second angle relative to an air bearing surface of the disk drive slider to remove a second portion of the air bearing surface. The second portion of the air bearing surface comprises a defect wherein the ion milling at the second angle reduces the height of the defect with respect to the air bearing surface.
