Abstract
A method for optimizing the attenuation of mechanical resonances of actuator driving energy of a disc drive is presented. The method generally involves determining a resonant frequency range of the disc drive, comparing the resonant frequency range to a filter coverage limit, failing the disc drive if the resonant frequency range exceeds the filter coverage limit, and storing notch filter constants in servo flash memory of a servo control processor if the filter coverage limit is not exceeded by the range of resonant frequencies. The notch filter constants configure the notch filter to attenuate the frequencies of the driving energy produced by the servo control processor that are within the resonant frequency range. The notch filter is implemented by the servo control processor each time the disc drive is used. Also presented is a disc drive and a program that are capable of implementing the above-described method.
