Title: Quek Leong Choo: Innovator in Wavelet Technology
Introduction
Quek Leong Choo is a prominent inventor based in Singapore, known for his contributions to wavelet technology. He holds a total of 10 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
Among his latest patents is the "In-line analyzer for wavelet based defect scanning." This invention provides a method and system for simultaneous localization of defects in both the time and frequency domain. A high-frequency repeating pattern is written on media, and the pattern is read to generate a readback signal, which is converted into ADC samples. The ADC samples are analyzed in-line to determine the type of wavelet, level of decomposition, and threshold level for a wavelet transform of the particular readback signal. The wavelet transform provides details and/or approximations (wavelet coefficients) that are analyzed to determine the type, location, and duration of any identified defects. Any noise in the details and/or approximations is removed by a wavelet-based denoising operation. Flags indicating the type, location, and duration of any defects are generated so that the defects may be mapped.
Another significant patent is "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 if a predetermined pattern is written at a particular radial offset from a target data track prior to testing a WPC register in association with the target data track. The selection of the particular radial offset can be performed according to an iterative offset track clean-up disclosed in the patent.
