发明名称 Longitudinal magnetic recording head with reduced side fringing
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.
