“…The design of the write module element was similar to that proposed in [10] and is shown in cross section in Figure 6. It consists of a nickel-zinc-ferrite substrate on which is deposited a film of gold patterned into a two-turn spiral winding.…”

“…Initial development work was aimed at nine-track enhancements for the 3420 series drives, based on earlier work by Bajorek et al on magnetoresistive read sensors [5]. Successful prototypes of a nine-track head were fabricated and tested, but they were not suitable for replacement of the conventional laminated heads [6][7][8][9][10]. Subsequent development efforts were aimed at an 18-track version, which ultimately resulted in the new thin-film head for the 3480.…”

The design of a magnetic head for use in the tape drive portion of the \BM 3480 IMagnetic Tape Subsystem required that advances be made in track density and linear recording density while meeting requirements for signal quality, manufacturability, and reliability. The design that was developed to fulfill these needs combines ferrite pole-pieces, magnetoresistive read elements, and planar-deposited write turns. This paper describes the read and write elements of the head and the approach used in the selection of the design parameters.
