Abstract
An analog signal processor for hard disk drive servo is described,lt p erforms servo demodulation by means of median peak detection which pro vides immunity against additive as well as multiplicative noise from t he medium, unlike conventional methods, A novel circuit configuration has been employed to implement the median peak detector in an area and power efficient manner, The entire servo processor that includes the demodulator and 10 b A/D and D/A converters has been integrated into a single CMOS integrated circuit.
