Title: Innovations of Charles H. Sobey
Introduction
Charles H. Sobey is a notable inventor based in Plano, Texas. He has made significant contributions to the field of data storage technology, holding a total of 6 patents. His work primarily focuses on methods and apparatuses that enhance the performance and reliability of mass data storage devices.
Latest Patents
One of his latest patents is titled "Method and apparatus for identifying a track of a rotating disk using EPR4 data equalization and detection techniques." This invention presents a method for identifying a track of a rotating disk in a mass data storage device, utilizing EPR4 data detection techniques. The track identification indicia can be written more densely than would have been possible without these techniques, allowing for overlapping pulses. The identification indicia is read from the disk using a read head and processed with EPR4 data equalization techniques in an EPR4 Viterbi detector, which can also switch to detect data pulses.
Another significant patent is "Apparatus for measuring and characterizing thermal asperities in a mass data storage device." This invention involves a method for characterizing a magnetic disk that contains data to be read by a magneto-resistive type head. The method includes writing a continuous signal onto the disk and reading it back using the magneto-resistive head. The read-back signal is compared to a threshold value, and areas of the disk where the energy exceeds this threshold are mapped.
