Latest Patents
One of his latest patents is titled "Method and apparatus for removing residual magnetization in a data transducer." This invention addresses the issue of residual magnetization in data transducers, such as recording heads used in data storage devices. The patent describes a residual magnetization sense circuit that detects the residual magnetization and a demagnetization current generator that effectively removes it. The demagnetization current is designed to taper to a final magnitude according to a selected profile, ensuring optimal performance during operation.
Another notable patent by Ray is "Apparatus and method for reducing nonlinearities in a position error signal (PES) of a disc drive data handling system." This invention aims to enhance the accuracy of read/write heads in disc drives by generating a sequence of PES samples indicative of head position. The method involves using a set of compensation values to reduce nonlinearities in the PES samples, which are iteratively updated to achieve a substantially linear PES across the radial width of each track.
