Title: Optical information recording/reproducing device

IPC: G11B7/09
Filed: 1992-02-25
Abstract: PURPOSE:To exactly execute leading-in by closing an AF after moving an objective lens to the vicinity of a focused position by using a sum signal from a split sensor, and closing an AT servo after detecting a fact that a tracking error signal is about '0'. CONSTITUTION:In a state that an objective lens 110 is near a card, signals S1+S4, S2+S3 of a split sensor 116, a sum signal I, and a difference signal H are all '0'. When the lens approaches a focused position, S1+S4 and S2+S3 are varied, I increases, and H is varied to the - side. At a focused point, I becomes maximum, and H becomes '0' again. In a distant state, I decreases, and H increases to the + side, and thereafter, decreases. In the beginning, an analog switch 203 selects the sum signal I. A focusing controller 304 increases a voltage level of a reference signal K from '0' and increases the sum signal I. In this case, since the lens is in a servo state, a deflection amount of the lens 110 is a little. By detecting zero crossing of the difference signal, and selecting the difference signal by a switch 203 by a signal J, AF servo leading-in is executed. Also, from the sum signal, it is detected that a light spot is on the track, and also, when an error signal is in the vicinity of '0', an AT servo is closed.
