ABSTRACT:
Embodiments of the present invention help to prevent, in a magnetic head slider adapted to be able to control flying height of a head element, the occurrence of excessive frictional force, even in case of contact with a magnetic disk, and suppress vibration of the slider. According to one embodiment, an air bearing surface of a magnetic head slider includes a deep groove, a shallow-trench rail about 100 nm higher than the deep groove, a rear end shoulder, two leading end pads about 1 μm higher than the deep groove, a trailing end pad about 970-995 nm higher than the deep groove, and an element pad about 5-30 nm higher than the trailing end pad and flush with the leading end pads. A head element includes a magnetic head element and a heater. The element pad has an area of 50-500 μm2, and the magnetic head element is disposed near a central section of the element pad.
