Abstract
According to one embodiment, a magnetic head includes a slider with an air bearing surface, and a head element in the slider. The slider includes a leading step at a leading side end of the air bearing surface, a trailing step at a trailing side end of the air bearing surface and including the head element, a deep groove formed between the leading step and the trailing step and opening to the air bearing surface, a center rail extending from a center portion of the air bearing surface to the trailing step, and a pair of pressure generators disposed between the center rail and each side edge.

A magnetic head comprising:
- a slider comprising an air bearing surface with a pair of side edges, a pair of side surfaces along the pair of side edges of the air bearing surface, a leading side end surface, and a trailing side end surface;
- and
- a head element in the slider, configured to process data, wherein
- the slider comprises a leading step at a leading side end of the air bearing surface, a trailing step at a trailing side end of the air bearing surface and including the head element, a deep groove formed between the leading step and the trailing step and opening to the air bearing surface and the pair of side surfaces, a center rail extending from a center portion of the air bearing surface to the trailing step, and a pair of pressure generators disposed between the center rail and each side edge, and
- each of the pressure generators comprises an intermediate pad extending from the center rail to the side edge side and bending toward the reading end side of the slider.
