Negative pressure air bearing slider

摘要

A negative pressure air bearing slider including a first air bearing surface formed on the bottom of the slider body at the upstream position so as to extend in the lateral direction of the slider body, and a pair of second air bearing surfaces formed on the bottom of the slider body separately from the first air bearing surface at downstream positions spaced in the lateral direction so as to define an air stream passage therebetween. The second air bearing surfaces serve to generate positive pressures that are spaced apart at downstream positions where a transducer element is embedded in the slider body, so that the slider's stiffness to rolling action can be enhanced. The cooperation of the front and rear rails enables for the creation of a higher negative pressure.
