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.

摘要: An inline processing system for patterning magnetic recording layers on hard discs for use in a hard disc drive. Discs are processed on both sides simultaneously in a vertical orientation, in round plate-like holders called MDCs. A plurality (as many as 10) discs are held in a dial carrier of the MDC, and transferred from one process station to another. The dial carrier of the MDC may be rotated and/or angled at up to 70° from normal in each process station, so that one or a plurality of process sources may treat the discs simultaneously. This configuration provides time savings and a reduction in the number and size of process sources needed. A mask enhancement process for patterning of magnetic media, and a filling and planarizing process used therewith, are also disclosed.
