Magnetic head slider with resistance to debris accumulation

摘要

A magnetic recording head for reading and writing information with respect to a rotating disk medium includes a pad region having a working surface which contacts the recording medium. The pad region has a leading edge and a trailing edge with the leading edge facing in the general direction of relative motion between the head and the medium. The leading edge has a narrower width than the trailing edge so as to reduce the effect of debris accumulation at the disk-head interface. The narrower leading edge allows the head to deflect oncoming debris as the head traverses the surface of the rotating magnetic medium.
