Abstract :
A single track magnetoresistive (MR) read/inductive write thin film magnetic recording tape head is described for a new class of Quarter-Inch tape cartridge drive systems. Thin film deposition processes were used to form the MR sensor with soft-adjacent-layer (SAL) biasing and the write element was formed primarily with electroplating techniques. The completed wafers were sliced into rows and single heads which were mounted in housings for contour lapping. The results of electrical and magnetic testing are compared to the product specifications
