Calibration of the write signal power level applied to a transducer for marking a moving media to optimize a later recovered read-back signal is provided. An optimized read-back signal is one where the peak-to-peak amplitude of the read-back signal is maximized. The method provides marking test patterns...http://www.google.com.tw/patents/US5268893?utm_source=gb-gplus-share專利 US5268893 - Write power calibration utilizing least squares fit of read-back signals for moving media memory
