Patent ID: 7843776

Claim:
A seek control method of an optical disk recording/reproducing apparatus, for moving an optical spot onto an arbitrary track, moving an optical pickup into a radial direction thereof to an optical information recording medium, forming lands and grooves spirally on an information recording surface thereof, comprising the following steps of: producing a tracking error signal upon reflection of the optical spot incident upon from said optical pickup, with movement into a radial direction thereof; producing a signal through differentiation of said tracking error signal; producing a digitized signal of tracking error signal through digitizing of said tracking error signal; producing a digitized differential signal of the tracking error signal, through digitizing the differential signal of said tracking error signal; and when conducting a seek control to move said optical spot across a plurality of tracks, starting a pulling operation of the optical spot of said optical pickup through a tracking servo, the starting of the pulling operation depending on said digitized tracking error signal and said digitized differential signal of the tracking error signal.
