Method and apparatus for reducing vibration on a disk spindle motor by detecting the vibrations and correcting the motor driving signal according to the detected vibration

Abstract

A method and an apparatus for recording and reproducing data on disk recording medium, capable of effectively reducing the unnecessary vibration of the spindle motor and the noises associated with it, and improving the tracking characteristic of a head with respect to the vibration of the spindle motor. The apparatus includes a head for recording and producing data with respect to a disk recording medium; a rotational driving mechanism including a spindle motor for driving the disk recording medium in rotation according to a driving waveform; and a waveform correction unit for detecting a vibration of the rotational driving mechanism and correcting the driving waveform supplied to the rotational driving mechanism according to the detected vibration. The apparatus can further includes a head driving mechanism for driving the head in a radial direction of the disk recording medium according to a driving signal; and a driving signal correction unit for correcting the driving signal supplied to the head driving mechanism according to the vibration of the rotational driving mechanism.
