Thin Film Heads - overview


Physics Accomplishment | 1960 - 1990

IBM researchers: Wolfgang Dietrich, Walter E. Proebster, Peter Wolf, V.S. Speriosu, Dean A. Herman, Jr., I.L. Sanders, T. Yogi

Where the work was done: IBM T.J. Watson Research Center, IBM Almaden Research Center

What we accomplished: Paraphrasing the Computer History Museum: "Thin-film processes employ photolithographic techniques, similar to those used on semiconductor devices, to fabricate disk drive heads, which read and write data from spinning magnetic disks. Thin film heads provide smaller size and greater precision than ferrite-based designs previously used for disk drive heads."
