Title: Tszlok Cheng: Innovator in Magnetic Head Technology
Introduction
Tszlok Cheng is a notable inventor based in Hong Kong, CN. He has made significant contributions to the field of magnetic head technology, holding 2 patents that showcase his innovative approach to measuring noise in magnetic heads.
Latest Patents
Cheng's latest patents include a method and system for measuring noise of a magnetic head. This method involves setting a plurality of threshold values, applying bias current or voltage to a read element of the magnetic head, and applying an external transverse magnetic field to the magnetic head. The process amplifies the output signal from the read element to produce an amplified signal, which is then filtered to create a filtered signal. An enable signal is generated for each threshold value within a predetermined time window by a counting control means, which uses input signals that include the filtered signal and the threshold value. The cumulative time duration of each enable signal is measured, leading to the creation of an amplitude-duration distribution based on the cumulative time durations and the threshold values. A variety of parameters are calculated according to this distribution, which are then analyzed using predetermined criteria to determine defects in the magnetic head. This invention also discloses a system for measuring noise of a magnetic head.
