摘要： According to one embodiment, a slider of a magnetic head is provided with a negative-pressure cavity formed in a facing surface, a leading step portion situated on the upstream side of the negative-pressure cavity, a pair of side portions opposed to each other, a trailing step portion situated on the outlet end side of the negative-pressure cavity, and a pair of embossed portions formed on the facing surface so as to project from the negative-pressure cavity and provided on the outlet side of the negative-pressure cavity with respect to an airflow. The embossed portions individually extend along a second direction so as to be situated individually on the opposite sides of the trailing step portion and are formed so as to be lower than the trailing step portion with respect to the negative-pressure cavity and flush with an outlet-side end surface of the slider.

摘要： 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.

摘要： A slider of a head has a negative-pressure cavity which is formed in the facing surface and generates a negative pressure, a leading step portion which protrudes from the facing surface and is situated on an upstream side of the air current with respect to the negative-pressure cavity, and a leading pad which is provided on the leading step portion and faces the recording medium. The leading pad has an inlet end edge which is situated on the upstream side of the air current and extends throughout a length of the leading step portion in the transverse direction, and a plurality of recesses which individually open in the inlet end edge and extend in the longitudinal direction from the inlet end edge.
