Abstract
According to one embodiment, a magnetic head includes a head slider including a bearing surface opposed to a surface of a recording medium, an inflow end face, and an outflow end face, and configured to fly by an airflow between the recording medium surface and the bearing surface, and a recording element and a reproduction element disposed in an outflow end portion of the head slider with respect to the airflow. The bearing surface of the head slider includes a trailing step on the outflow end portion, a trailing pad on the trailing step and includes an outflow end kept at an inflow-side gap away from the outflow end face, and a first groove formed along a step portion at a boundary between the trailing step and the trailing pad.
