ABSTRACT:
An information recording and/or reproducing apparatus includes an optical system for irradiating a light beam to one of tracks arranged in parallel on a recording medium, an actuator for moving the optical system across the tracks, a circuit for alternately applying a jumping signal and a braking signal of the opposite polarity to the actuator to direct the light beam to a desired track, a tracking signal detector for intermittently sampling a tracking error signal varying between a positive value and a negative value with the movement of the optical system across the tracks, a memory for storing the sampled signals, and a switching timing detector for multiplying or adding the sampled signal and the previously sampled signal stored in the memory and causing the signal application circuit to switch from the jumping signal to the braking signal when the product or sum is zero or negative.
