摘要： A magnetic read/write head is produced with an insert layer between the substrate and the magnetic transducer. The insert layer has a lower coefficient of thermal expansion than the substrate, which reduces the temperature pole tip recession (T-PTR) of the head because the insert layer is an intervening layer between the substrate and magnetic transducer. The insert layer is produced by plating, e.g., an Invar layer over the substrate prior to fabricating the magnetic transducer. The Invar layer is annealed and the structure planarized prior to depositing a non-magnetic gap layer followed by the fabrication of the magnetic transducer.

摘要： An electroplated film is deposited over a substrate with a plating frame pattern that includes a plating field defined by a plurality of individual features. By dividing the plating field into a plurality of individual features, the delamination force at any location on the plating field is greatly reduced. Thus, a film with a large stress, such as a high moment film, may be plated to a greater thickness than is possible with conventionally plated films.
