Abstract:
A magnetic head for use in a disk drive having a disk that is rotated during operation of the disk drive and stationary during non-operation, said magnetic head comprising:a slider including an air inflow edge, an air outflow edge and an air bearing surface;a transducer mounted at the air outflow edge;said slider and said transducer being relative to the surface of the disk to fly above the surface of the disk during rotation of the disk for reading and writing data from and to the disk, and to come to rest on the surface of the disk during non-operation of the disk drive; anda plurality of projections formed on the air bearing surface in a manner so that during operation of the disk drive, spacing between a lowest one of said plurality of projections and the surface of the disk is greater than spacing between the air outflow edge and the surface of the disk, and, in a transition between operation and non-operation of the disk drive, at a preselected time before contact with the surface of the disk, spacing between said lowest one of said plurality of projections and the surface of the disk is less than spacing between the air outflow edge and the surface of the disk.
