Abstract:
1. A slider comprising: a head for recording and/or reproducing data on/from a disk medium; an air bearing surface having a concave part for generating negative pressure; and an air influx side pad located at an air influx end side of the concave part, the air influx side pad crossing a center of the slider in a slider longitudinal direction and being located at a top approximately plane surface of the air bearing surface, wherein when a relative velocity between the slider and the disk medium, at a position where a skew angle formed by an ordinate passing through the center of the slider in the slider longitudinal direction and a disk rotating direction is 0 (rad), is V (mm/s), a difference in level between the top approximately plane surface of the air influx side pad and an approximately plane surface formed at an air influx end side of the air influx side pad is “d” (mm), and a distance from an air influx end of the slider to the air influx side pad is “y” (mm), the following expression is obtained:
