Title: The Innovations of Andrew S. Kao
Introduction
Andrew S. Kao is a notable inventor based in Fremont, CA (US). He has made significant contributions to the field of technology, particularly in the area of magneto-resistive heads. With a total of 2 patents, his work has had a considerable impact on the industry.
Latest Patents
Kao's latest patents include a method for magneto-resistive head electrostatic popping detection. This method and system are designed to detect electrostatic noise in a magneto-resistive head, which may arise from various conditions manifesting in the frequency domain as either an amplitude spike or an unstable baseline. In one embodiment, the signals generated by the head when reading a DC-erased track are compared. When viewed in the frequency domain, the spectrum gap between the signals is utilized to determine if the head being tested suffers from defects causing an unstable baseline or from defects causing an amplitude spike.
Another significant patent is a scheme to avoid electrostatic discharge damage to MR/GMR head gimbal/stack assembly in hard disk applications. This innovation involves a flexible circuit board that can be assembled into a head gimbal assembly of a hard disk drive. The flexible circuit board may feature a conductive tab that is electrically connected to a pre-amp pad and a head pad of the circuit board. The head pad may be connected to a head, and the conductive tab can be grounded during handling of the flexible circuit board. This design ensures that any electrostatic discharge on the head may be grounded through the conductive tab.
