Abstract
A compact slider has a reduced area of bearing surfaces, thus remarkably decreasing a lifting force obtained by an air bearing characteristic. In one embodiment, a shallowly grooved surface is disposed on an inflow side of a bearing surface of a slider, and a pair of inflow side air bearing surfaces are disposed rearward of and adjacently to the shallowly grooved surface. Side shallowly grooved surfaces are disposed on both sides rearward of the air bearing surfaces in such a manner as to extend near an outflow end. A center air bearing surface is disposed at a center in a width direction at the outflow end of the slider. A magnetic head is mounted at the center air bearing surface. A center shallowly grooved surface is disposed on an inflow side of the center air bearing surface. A deeply grooved surface is disposed at a center of the bearing surface surrounded substantially by the air bearing surfaces, the side shallowly grooved surface, and the center shallowly grooved surface. The ratio of a slider length Lx to a slider width Ly satisfies the following inequality: 1.35≦Lx/Ly≦1.8, where the slider width Ly is 0.8 mm or less.
