Abstract:
A method for reducing the travel time of an optical pick-up, comprising the steps of:(i) detecting the number of revolutions of an optical disk in a unit time, so as to obtain a first number of track-jumping signals detected by the optical pick-up due to the rotation of the optical disk in the unit time;(ii) adding the first number of track-jumping signals to a second number of track-jumping signals detected by a pick-up controller in the unit time in the case that the optical pick-up moves outward, and subtracting the first number of track-jumping signals from the second number of track-jumping signals detected by the pick-up controller in the unit time in the case that the optical pick-up moves inward, to calculate a real number of tracks being jumped by the optical pick-up in the unit time; and(iii) controlling the tracking of the optical pick-up based on the real number of tracks being jumped.
