DATA RECORDING/REPRODUCING APPARATUS FOR OPTICAL CARD

摘要

A card support is reciprocally moved by a driver (109) in a first direction. Optical heads (103) are reciprocally moved by a driver (108) in a second direction which is at right angles to the first. Motors in the drives are surrounded by metallic vibration isolators and a rubber vibration isolator. Position of the optical card is determined by a presser for urging the upper surface of the optical card downwardly and by a positioner contacting the side surface of the card. The optical card inserted from the external side is placed in position by a roller which has a tilted rotary shaft. The optical head (103) is usually controlled by feedback. When the drive speed has dropped, however, the open-loop control is carried out. The optical head is provided with electromagnetic drives to scan the optical card. Signals read by the optical head are processed by a special binary circuit.
