摘要： The application discloses a magnetic pole assembly having a pole tip arranged in a magnetic flux path and side shields separated from the pole tip by non-magnetic gap regions. The side shields are shaped to provide a differential shielding effect alongside the pole tip. As described, the sides shields are shaped to provide a non-magnetic gap region having a width that increases in the downtrack direction along a length of the pole tip. The increasing non-magnetic gap region alongside the pole tip provides a smaller non-magnetic gap region separating the pole tip from the side shields at the leading edge than the non-magnetic gap region separating the pole tip from the side shields at the trailing edge of the pole tip.

摘要： A longitudinal recording head for use with magnetic recording media includes first and second writes poles in which the second pole has sides that wrap around a portion of the first pole in order to reduce or eliminate side fringing fields. The wrapped around sides of the second pole have relatively small cross sections away from the air bearing surface of the recording head, and relatively large cross sections at the air bearing surface. The sides may saturate in the narrow regions away from the air bearing surface, but do not saturate in the broad regions adjacent the air bearing surface. Longitudinal recording heads incorporating the wrapped around second pole sides effectively reduce or eliminate side fringing and are capable of improved recording densities.

摘要： A pole tip shield (200) for a write element of a recording head is disclosed. The pole tip shield is spaced from the pole tip (148) in the leading edge direction to provide a magnetic wall angle to reduce ATI or adjacent track erasure to compensate for the skew angle of the head. In illustrated embodiments, the pole tip shield includes side portions (204). In illustrated embodiments the pole tip shield is generally "U" shaped and side portions of the pole tip shield include different thickness or width dimensions. In illustrated embodiments, the pole tip shield provides a magnetic wall angle for a rectangular shaped pole tip. Embodiments disclosed in the application include a trailing edge shield (240) separated from the pole tip shield along an air bearing surface of the head by a non-magnetic gap portion.
