Title: Fred S. Lee: Innovator in Magnetic Recording Technology
Introduction
Fred S. Lee is a notable inventor based in Oklahoma City, OK, with a significant contribution to the field of magnetic recording technology. He holds a total of seven patents, showcasing his innovative approach to developing advanced manufacturing methods for magnetic recording heads.
Latest Patents
Among his latest patents, Lee has developed a "Method of making thin film magnetic recording heads." This patent outlines a manufacturing process for creating a novel magnetic read/write transducer head utilizing thin film materials. The method involves depositing a thin film magnetic recording head on a selected substrate, allowing for batch manufacturing of the transducer in conjunction with its supporting slider assembly. The substrate, made from a selected material in large wafer form, undergoes a series of thin film deposition, etching, and plating operations to produce multiple thin film magnetic heads. Afterward, the substrate wafer is diced around each transducer head, followed by finishing and polishing to achieve the desired shape for the complete slider and transducer head assembly.
Another significant patent is the "Method of making a thin film magnetic head." This invention describes a thin film magnetic head that includes a substrate, a first layer of magnetic material with a first offset portion, a second layer of magnetic material with a second offset portion overlying the first, and a layer of conductor material within the cavity defined by the two offset portions. The design allows for variations in the placement of the first magnetic layer, either within a recess in the substrate or between insulation layers mounted on the substrate's top surface.
