Title: Joseph J Lum - Innovator in Magnetic Storage Technology
Introduction
Joseph J Lum is a notable inventor based in San Jose, California. He has made significant contributions to the field of magnetic storage technology. His innovative work has led to the development of a unique method and apparatus for in-situ measurement of head and recording medium.
Latest Patents
Joseph J Lum holds a patent for a method and apparatus that measures the flying height of a slider supporting a magnetic transducer in-situ within an operational magnetic disk storage system. This invention allows for the production of relative motion between the magnetic transducer and a magnetic recording medium at a first velocity. The resulting air bearing positions the magnetic transducer slider at a specific flying height from the magnetic medium. The method involves writing a single signal of constant periodicity over a predetermined area of the recording medium and sensing a readback signal to produce a first signal. The flying height is then calculated based on the ratio of the first and second signals.
