DISK DRIVE AND METHOD FOR ADJUSTING COMMON-MODE VOLTAGE OF AN ELEMENT ON A HEAD-SLIDER |
摘要 |
A disk drive. The disk drive includes a disk configured to store data, a motor configured to rotate the disk, a head-slider and a controller. The head-slider includes a slider configured to fly in proximity to a recording surface of the disk, and an element on the slider. The controller is configured to measure a fly height between the head-slider and the disk at different common-mode voltages of the element to determine an operational common-mode voltage from a measurement result.
