  • Dynamic test glide head calibration using laser adjustment
    Patent number: 8338742
    Abstract: Methods and apparatus for the calibration and use of test glide head gimbal assemblies are disclosed. Calibration is performed by pulse laser adjustment of the flexure mounted to the glide head, while the head is flying above a media test disk having asperities of known dimensions. The calibration process normalizes the fly heights of glide heads used to measure defects on both upper and lower surfaces of disk drive media, allowing upper and lower surfaces to be scanned simultaneously.
