A hard disk drive includes a base member, a disk which is a data storage medium to rotate at a high speed on the base member, and a head stack assembly (HSA) having a head slider including a magnetic head to write data on the disk or to reproduce data recorded on the disc, and an ABS pattern formed on a disk facing surface of the head slider to generate a lifting force, and is rotatably mounted on the base member so that the head slider moves between inner circumferences and outer circumferences of the disk in a floating state over the disc, wherein if a center line of the ABS pattern is an ABS line and a straight line extending in a direction in which an air flow induced due to the high speed rotation of the disk enters the ABS pattern is an air flow line, a crossing angle between the ABS line and the air flow line is reduced as the head slider moves from the outer circumferences to the inner circumferences. |
