Head-slider configured to have multiple depth surfaces to avoid contact with a magnetic-recording disk wherein a leading side surface is deeper than a negative pressure deep recessed surface

摘要

A head-slider. The head-slider includes a magnetic-recording head and an air-bearing surface. The air-bearing surface includes air-bearing portions, shallow-recessed surfaces, and a deep-recessed surface. Air-bearing portions are configured to fly nearest to a magnetic-recording disk; shallow-recessed surfaces have a first depth from the air-bearing portions; the deep-recessed surface has a second depth, larger than the first depth, from the air-bearing portions. Air-bearing portions and shallow-recessed surfaces are configured to generate positive pressure; and, the deep-recessed surface is configured to generate negative pressure. A shallow-recessed surface is disposed near a leading edge of the head-slider; air-bearing portions are preceded and abutted by the shallow-recessed surface; a plurality of small leading-end pads are disposed near a leading edge, and at least at each side of the shallow-recessed surface near lateral sides, of the head-slider; and, a leading-end deep-recessed surface is disposed at a leading side of the leading-end pads.
