Abstract
According to one embodiment, a head of a disk device has a slider and a head portion disposed on the slider. The slider has a facing surface opposed to a surface of a rotatable recording medium and is flown by an airflow. The facing surface of the slider has a first direction extending in a direction of the airflow and a second direction perpendicular to the first direction. The slider includes a negative-pressure cavity, a leading step portion, a leading pad which protrudes from the leading step portion, a recess which is formed in that part of the leading step portion which is situated on an upstream side of the leading pad with respect to the airflow and defines a first step portion and a second step portion which individually extend in a direction across the first direction and are spaced in the first direction, and a trailing step portion.
