Latest Patents
David Niemann holds a patent for a "Self compensating high density data recording and detection scheme." This invention utilizes a dual frequency data writing scheme. At a first frequency, flux transitions are achieved, resulting in large excursions of the information signal. The first frequency approximates the maximum frequency at which such excursions can occur. A second higher frequency is utilized to create very small or no excursions. At this second frequency, a complex flux transition is not achieved, resulting in little or no information signal. Information is represented by the presence or absence of excursions. The first frequency is approximately 33,000 flux changes per inch, while the second frequency is around 67,000 flux changes per inch. An adaptive, self-compensating scheme is employed to detect data written by this method. This scheme is self-adjusting in real time and provides recovery of the nominal flux transition independent of the information pattern. Data recovery is qualified through a novel excursion detection scheme that compares variations in the tracking peak detect value with the input signal separated by an excursion threshold value.
