Latest Patents

Among his latest patents is the "Head with active fly height control." This invention describes an apparatus and method for evaluating surface characteristics of a recording disc prior to its incorporation into a disc drive. The glide test system includes a glide test head that is supported over the disc, featuring a negative-pressure air bearing slider and a contact sensor. This sensor outputs a signal when the glide test head contacts a feature of the disc surface. The glide test head and the disc are characterized as opposing plates of a variable capacitor, with a dielectric layer that includes at least a layer of air supporting the glide test head. A voltage source applies a fly height control voltage across the capacitor to adjust the fly height of the glide test head. The disc surface is designed with a data region for magnetically storing data and a texturized landing zone to support the read/write head when the disc is stopped.

Another significant patent is the "Method for controlling flying height of a magnetic head." This method involves controlling the flying height at the interface of a magnetic head and a magnetic storage medium by applying a voltage between the head and the medium. This voltage controls the vertical movement of the head, allowing for adjustments in the flying height. The method is particularly useful for achieving high writing and reading density, especially when the surface texture of the medium is optimized.
