Abstract:
A magnetic head air bearing slider having an air bearing surface, a first side and a second side substantially parallel to said first side, a leading edge and a trailing edge extending between said first and second sides, a central longitudinal axis extending from said leading edge to said trailing edge, comprising:a center pad extending towards said trailing edge, said center pad formed with a polygon-shaped top portion, a middle narrow rectangular waist portion, and a bottom foot portion, said center pad being asymmetrical with reference to said central longitudinal axis, said waist portion being between said top portion and said bottom foot portion, all of said portions being asymmetrical relative to said central longitudinal axis, and wherein said top portion is closer to said leading edge than said waist portion and said bottom foot portion;first and second side pads extending towards said trailing edge;said center pad and said side pads defining the air bearing surface;a T-shaped recess region abutting said center pad and extending from said bottom foot portion to said leading edge thereby entirely encompassing said center pad, said T-shaped recess region having a lateral portion at the leading edge extending continuously from said first side to said second side, said T-shaped region being etched to a first depth relative to said air bearing surface;a major recess region formed between said T-shaped region and said side pads and extending to said trailing edge, said major recess region being etched to a second depth relative to said air bearing surface, said second depth being greater than said first depth.
