Abstract
A magnetic recording head for reading and writing information with respect to a rotating disk medium includes a pad having a working surface which contacts the recording medium. The pad 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 ledge has a narrower width than the trailing edge so as to reduce the effort 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.
Claims1
A recording head for reading and writing information with respect to a rotating disk medium, said head including a pad having a working surface which contacts said medium during the reading/writing process, a magnetic pole tip structure being embedded within said pad, wherein said pad has a leading edge and a trailing edge with said leading edge facing in the general direction of relative motion between said head and said medium, said pad has a V-shape with the narrow part of said V-shape pointing in said direction, and said leading edge has a narrower width than said trailing edge.
