Abstract
A slider maintains a uniform flying posture and a predetermined flying height by suppressing variations of roll angle and flying height. At an air bearing surface of the slider, an edge line on an air influx end side and an edge line at a disk outer circumference side end are connected by an edge line having a recess angle θ (rad) with respect to an abscissa. The edge line on the air influx end side and an edge line at the disk inner circumference side end are connected by an edge line having a recess angle η (rad) with respect to the abscissa, thereby forming a concave part, and when a distance 'x' from an air influx end to the concave part of the air bearing surface is standardized by a length L of the slider to make X=x/L, the recess angles θ and η are as follows: 0.06×π/X<θ<0.12×π/X, and 0.05×π/X<η<0.13×π/X.
