Title: Harlan P Mathews: Innovator in Magnetic Data Storage Technology
Introduction
Harlan P Mathews is a notable inventor based in Boulder, Colorado, recognized for his significant contributions to the field of magnetic data storage technology. With a total of 15 patents to his name, Mathews has developed innovative solutions that enhance the performance and reliability of data storage systems.
Latest Patents
Among his latest patents is the invention titled "Mr head read signal preconditioning circuitry." This invention relates to circuitry designed for processing an analog read signal, such as that produced by a magnetoresistive head in a magnetic data storage system. The circuitry processes the analog signal before it reaches the detector, which converts the analog signal into a digital representation of the data originally stored on the magnetic medium. One embodiment of this invention includes circuitry that equalizes the amplitudes of the positive and negative pulses in the analog read signal. Another embodiment focuses on reducing the baseline shift of the analog read signal, making it applicable in various magnetic data storage systems utilizing conventional data detection methods.
Another significant patent is the "Method for fabricating a dual element head." This method involves depositing a first head element on a substrate, followed by the deposition of a second head element on the first. Each deposition step has a tolerance that is independent of the other. The second head element is initially made wider than the desired functional width and is then trimmed to achieve the desired width while using a portion of the first head element as a reference. This innovative approach reduces errors associated with the independent tolerances of the two elements.
