Title: Innovations of Inventor Hong Tian

Introduction

Hong Tian is a notable inventor based in Milpitas, CA (US). He has made significant contributions to the field of disk drive technology, holding a total of 4 patents. His work focuses on overcoming challenges related to disk drive performance and reliability.

Latest Patents

One of his latest patents is the "Disk drive stiction release system." This invention addresses the issue of stiction, where the heads of a disk drive adhere to the disk surface when at rest. The system includes firmware that rapidly fluctuates the voltage to the spindle motor and/or actuator motor upon start-up. This pulsing action creates forces in multiple radial directions, allowing the heads to break free from the disks. Additionally, the firmware adapts to the resonant frequency of the spindle motor, ensuring effective operation regardless of the number of heads stuck.

Another significant patent is the "Method for detection of slider-disk contact." This method involves testing the contact between the slider and disk in a disk drive. It includes positioning the head over preselected tracks while rotating the disk at a specific velocity. The head writes a signal on the disk, which is later read back to determine the rotational velocities at which slider/disk contact occurs. This innovation enhances the understanding of disk drive dynamics and improves overall performance.
