Abstract
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.
Claims9
A recording head for reading and writing information with respect to a rotating disk medium, said head including a pad region having a working surface which contacts said medium during the reading/writing process, a magnetic pole structure being embedded within said pad region, said pad region having 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, and wherein said leading edge has a narrower width than said trailing edge.
A slider for supporting a magnetic transducer above the surface of a rotating disk medium, said slider comprising:
- a body;
- a plurality of rail members extending outward from said body in a direction towards said medium, each of said rail members having a leading and a trailing edge with said leading edge facing in the general direction of relative motion between said head and said medium, and wherein said leading edge has a narrower width as compared to said trailing edge;
- each of said rail members also having an air-bearing surface which is alternately brought into contact with and separated from said surface of said medium, said air-bearing surface being generally parallel to said surface of said medium.
