ABSTRACT:
An optical card processing apparatus is disclosed in which an optical head producing an irradiating light beam is forcibly moved in a direction orthogonal to a direction of tracks of an optical card set in the apparatus. A tracking error signal as the moving light beam irradiates the card is analyzed to determine if the optical card is properly set in the apparatus.
