Abstract Scanning Optical Card Reader An optical data card random access information system featuring a data card with data tracks transverse to the lengthwise direction of motion of the card in a transport. An electromechanical actuator, having an arm parallel to the tracks, supports a light source for illuminating a track as well as a charge coupled device linear array detector for reading data. Light is directed onto a desired track to be read and preferably the entire track is imaged onto elements of the detector array so that an entire track may be read simultaneously. The card is supported by a carriage which advances the card in the card's lengthwise direction under control of a motor. The lengthwise motion of the card places any desired track under the actuator arm, while crosswise motion of the arm is able to place the track within the field of view of the detector.
