Abstract

A read-only storage device is described that employs punched microholes in an opaque card. These holes are selectively illuminated from one side of the card, and the light spots are then detected by sensors on the other side of the card. The dimension of the combined matrix allows high density reading of video data without the space, cost and complexity of any moving parts. Data densities better than that of a compact video diskette are possible. THE DATA CARD
