Latest Patents

Jianping Chen holds a patent titled "System and method for measuring erase band widths on magnetic media." This patent describes a method for measuring the width of an erase band located adjacent to a test track containing a periodic signal at a specified frequency. The process involves reading an information signal as a read head traverses the erase band and test track. Signal level data points are stored, representing the amplitude of the fundamental frequency obtained from a Fourier transform of the information signal. Additionally, media noise level data points are stored, representing an integration of a noise power spectrum obtained from the Fourier spectrum of the information signal over a predetermined frequency range. The width of the erase band is derived by computing the absolute value of the difference between the positions of the edge of the test track and the edge of the erase band.
