ことを特徴とする光カード装置。 An optical pickup that optically performs recording and reproduction on a rectangular optical card and a rotation device that rotates the optical card during recording and reproduction are provided, and a plurality of concentric recording tracks are formed on the optical card from the center position of the card. and a seek motor that is positioned outside the outermost recording track on both sides in the longitudinal direction of the optical card to form a plurality of concentric arc-shaped recording tracks, and moves and displaces the optical pickup in a direction perpendicular to the recording track. A D/D is provided to supply this seek motor with a voltage corresponding to the recording track.
A converter is provided, and storage means is provided in the optical card for storing a digital value of the voltage supplied to the seek motor within a track pull-in period;
An optical card device comprising tracking control means for controlling the optical pickup using data obtained by adding a digital value corresponding to the pitch of the recording track to the digital value stored in the storage means when a recording track is selected.
