ABSTRACT:
A data card recording system having a rotatable drum for supporting a plurality of data cards on its circumferential surface. A light source emits a beam which is modulated in response to data and directed to the cards on the rotating drum. The beam produces data spots in a plurality of parallel tracks aligned in the direction of drum rotation on a recording strip whose length is parallel to the drum axis. The focusing optics may be moved transversely to record in adjacent tracks. A data segment accessed from a data source and stored in a register of a microprocessor is recorded on a track on each card on the drum. A data control, controlling modulation rate, and a position detector unit are provided to synchronize the light beam modulation with the drum rotation rate. Drums and optical system embodiments are described for both reflectively and transmissively read data cards.
