Title: Fong Kheon Chong: Innovator in Disk Drive Technology
Introduction
Fong Kheon Chong is a notable inventor based in Singapore, recognized for his contributions to disk drive technology. He has been awarded 5 patents for his innovative work, particularly in the area of noise mitigation and read-to-write head offset optimization.
Latest Patents
One of his latest patents is titled "Noise mitigation for write precompensation tuning." This technology provides techniques for mitigating write-to-write bit error rate fluctuations that decrease the accuracy of write precompensation (WPC) tuning. According to one implementation, such fluctuations are mitigated by writing a predetermined pattern at a specific radial offset from a target data track prior to testing a WPC register associated with that track. The selection of this radial offset can be performed according to an iterative offset track clean-up process disclosed in the patent.
Another significant patent is the "Method and apparatus for determining read-to-write head offset of a disk drive." This method optimizes the read-to-write offset of a disk drive system concerning a track. It includes determining a first read position among a range of test positions offset relative to the track based on read signal strength. The method further involves calculating a subrange of test positions around the first read position, selecting a second read position based on bit error rates, and setting the read-to-write offset as a function of this second read position.
