System Design Study for Human Readable Machine Readable (HRMR) Information Processor.
Abstract
A study was conducted to determine the feasibility of a system that will record, in parallel, both human readable and machine readable information on a microfiche. The first phase, described in AD-715 983, investigated methods for recording the machine readable information. It concluded that holographic methods are superior to direct recording for this application. This final report represents the over-all design for the HRMR system. Two alternate approaches are described, the choice between them being dependent on locating a suitable film for the recording of the holographic information. In the first approach all information is recorded with a laser, while in the second system the human readable information is recorded with a CRT and the machine readable data is recorded with Light Emitting Diodes. Recording times for the two approaches are 84 seconds and 30 seconds, respectively.
