Abstract: A method and apparatus for the enhancement of embedded runout correction in a disk drive is provided. According to the present invention, embedded runout correction values are obtained by convolving a position error signal due to repeatable runout for a track with an inverse impulse response describing the response of a transducer head servo system to a given input. According to the present invention, the inverse impulse response is determined by introducing an impulse to a transducer head servo system, and measuring the response of the system in the time domain. The response is transformed to the frequency domain to form an error transfer function, the reciprocal is taken, and the function is transformed back into the time domain. The inverse impulse response, according to the present invention, is obtained for at least every transducer head in a disk drive capable of addressing a track for which embedded runout correction is desired.
