摘要： An inductive write element for use with a magnetic data recording and retrieval system is provided. The write element includes a magnetic yoke having an electrically conductive coil passing there through. The yoke is constructed of first and second magnetic poles, and performance of the write element is improved by the inclusion of a very thin pedestal of a high magnetic moment material on the first pole in the pole tip region. Further performance gains are realized by providing a tapered edge on the pedestal to facilitate magnetic flux flow through the pedestal.

摘要： A magnetic thin film includes a ferrite-containing underlayer and a ferrite-containing top layer. The composition of the underlayer differs from that of the top layer. During ex-situ annealing of the thin film structure, the underlayer inhibits diffusion of substrate atoms into the top layer. The composition of the underlayer relative to the top layer suppresses grain nucleation within the underlayer relative to the top layer at high temperatures and inhibits the nucleation of grains within the underlayer having undesirable composition, crystal structure, and orientation.

摘要： The present disclosure describes a method for manufacturing a full wraparound shield damascene write head through the implementation of a three layered (tri-layered) hard mask. According to an embodiment of the invention, the various layers of hard mask are used for different purposes during the formation of a write head. The wraparound shield head of the present invention exhibits improved physical characteristics that further result in improved performance characteristics. Use of the hard mask layers according to the present invention allows for use of manufacturing processes that can be more closely controlled than those processes used in other processes. For example, smaller dimension lithographic techniques can be used. Also, reliance on certain CMP processes is not necessary where the use of CMP processes is not as well-controlled as deposition or lithographic techniques as is possible using the present invention.
