A method and an apparatus for recording and reproducing data on a 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.
