Latest Patents
Among his latest patents, Gong has developed a method and apparatus for controlling data read/write between a hard disk and a hard disk controller. This invention involves detecting and filtering a position error signal amplitude, which indicates the distance between the expected and actual positions of a magnetic head in a magnetic data storage system. The filtered signal generates a sway mode signal amplitude that reflects oscillations of the magnetic head. If this amplitude exceeds a predetermined threshold, a warning signal is triggered to prevent potential head-disk crashes.
Another significant patent by Gong is a predictive failure analysis technique for head crashes in hard drives. This method also utilizes a position error signal to determine the distance between the expected and actual positions of the magnetic head. By storing and analyzing these signals over several revolutions, Gong's invention can predict the likelihood of a head-disk crash, thereby enhancing the safety and reliability of hard drives.
