Abstract:
1. A magnetic head slider, comprising: a slider including: two air bearing surfaces disposed respectively in contact with both ends, on an air inflow side, of a medium opposing surface; a connection air bearing surface configured to connect the two air bearing surfaces together on the air inflow side, wherein the two air bearing surfaces are level with the connection air bearing surface; a shallowly grooved surface disposed in contact with both the ends of the medium opposing surface between the two air bearing surfaces and the connection air bearing surface, and an air inflow end of the medium opposing surface; side shallowly grooved surfaces disposed respectively rearward of the two air bearing surfaces and in contact with both the ends of the medium opposing surface, and extending to points near an air outflow end of the medium opposing surface; a center air bearing surface disposed at a central portion in a width direction on the air outflow end of the medium opposing surface; a center shallowly grooved surface disposed on an air inflow side of the center air bearing surface; and a deeply grooved surface surrounded substantially by the two air bearing surfaces, the connection air bearing surface, the side shallowly grooved surfaces, and the center air bearing surface; and a magnetic head disposed on the center air bearing surface; wherein the ends of the medium opposing surface are respective end faces in the width direction of the slider, and wherein the slider has a width of about 0.8 mm or less and the medium opposing surface is flat or protrudent in the width direction.
