Latest Patents
Peter Chen-I Fang holds a patent for a process titled "Process for measuring nonlinear transition shift (NLTS) at high recording densities with a giant magnetoresistive (GMR) head." This invention presents a nonlinear transition shift (NLTS) measurement procedure for read/write heads that utilize giant magnetoresistive (GMR) merged heads. The method incorporates pulse-shape distortion effects on recording nonlinearity, which can significantly impact existing theoretical formulae for calculating nonlinearity correction factors from measured partial erasure values. The procedure also includes a second-order approximation of the equation of NLTS and nonlinearity correction factors. Transition broadening effects (TBE) and partial erasure (PE) are integrated into the NLTS measurement process to allow for accurate isolation of the NLTS from unrelated TBE/PE and GMR nonlinear transfer characteristics (NTC). The process involves performing a fifth harmonic elimination (5HE) test to measure a first nonlinearity value, followed by two partial erasure tests at different densities to compute the NLTS by combining the measured values.
