Abstract
A magnetic-recording-disk test-head. The magnetic-recording-disk test-head includes a slider, a test pad and a slider-surface-shape control mechanism. The slider includes a leading edge and a trailing edge. The test pad is disposed at a trailing-edge side of the slider and is configured to remove and to detect asperities on a magnetic-recording disk. The slider-surface-shape control mechanism is configured to change a shape of an air-bearing surface of the slider and is disposed at a leading-edge side of the slider.
