ABSTRACT:
A suspension for use in a magnetic disk drive comprised of a flexible load beam and a slider. The flexible load beam is comprised of a two-layer laminate and air bearing structure is formed in one of the layers. Part of the flexible load beam rests on a data storage disk when the disk is not rotating. When the disk begins rotating, the air bearing structure causes the load beam to fly above the surface of the disk at a first flying height. Similarly, when the disk begins rotating, the air bearing surface of the slider causes the slider to fly above the surface of the disk at a second flying height. Typically, the first flying height is about ten times greater than the second flying height.
