Latest Patents

Chen's latest patents include a "Test method to measure lubricant mobility on a hard drive disk" and a "Clearance sweep test." The first patent outlines a method for measuring the mobility of a lubricant on the top surface of a disk used in hard disk drives. This method involves forming scribe lines in the lubricant layer and spinning the disk to observe how the lubricant moves under centrifugal forces. The height of the lubricant that enters the scribe line is then measured to assess its mobility. The second patent describes a calibration method for a fly-on-demand head of a hard disk drive. This method includes flying a head over a lubricant-covered test track and applying voltage to a heating element to adjust the head's proximity to the disk. The process allows for the determination of fly height and helps mitigate wear patterns in the lubricant.
