We studied a magnetic recording head of a three-pad-slider which had flat-inclined air-bearing surfaces. We expected a small friction force and a small velocity dependence on the flying height from the configuration. We confirmed these expectations by manufacturing heads with MR elements. We also performed continuous 1000-hour seek tests and read/write tests and found that the variation of signal amplitude was less than ±20 percent. After the tests, there was no measurable wear for three heads at the front contact pads and the rear contact pads among the total four tested heads. There was no measurable wear on the disk surface as well. These results demonstrate the sufficient durability of the head-disk interface.
