ABSTRACT:
A document containing analog data is vacuum retained on a transparent rotating drum. A data illumination head and a light responsive reading head are mounted on a carriage which moves parallel to the axis of rotation. The heads transversely scan the existing analog data as the drum rotates generating a digital new data base. The carriage is supported on air bearings that constrain movement in pitch, yaw and roll, and is driven by a precision lead screw. The sample rate of the read head is controlled by a step accumulator in response to a shaft encoder which monitors the drum rotation.
