Thin-film magnetic recording head using a plated metal gap layer |
摘要 |
A first layer of magnetic material is deposited onto a substrate to form a bottom pole of an inductive transducer. A second layer of magnetic material is plated on the first layer of magnetic material within the pole tip region to form a bottom pole extension. A layer of non-magnetic metal is then plated on the bottom pole extension to form the gap. A third layer of magnetic material is then plated on the gap layer to form the top pole extension. In one form of the invention, a mask is employed to define a good zero throat level surface to the pole tip region.
