Abstract
Tracks formed on an optical card loaded into a card holder are scanned so that ID information about a reference position on the card is read. This ID information may be used to correct an appraisal of where the card is loaded on the card holder. If the correction operation fails, then the optical head is moved in a direction transverse to the tracks to again perform the correction operation at another track.
