Abstract : This report presents the results of the second part of a two-part study program for the conceptual development and design study of a Human Readable Machine Readable Information Processor that uses the Committee on Scientific and Technical Information (COSATI) standard 4-inch by 6-inch microfiche as the storage medium for machine as well as human readable information. Alternative approaches for laser recording/readout of the required machine readable data (2,500,000 digital bits) were investigated under the first part of the program. A Frequency Level Encoding approach was selected for data recording while two approaches, Flying Spot Readout and Coherent Readout, were identified as being equally applicable to the readout task. Under this part of the program, the Digital Recorder was designed using a flat-field laser scanning mechanism while the Digital Data Reader was designed using the identical scanning mechanism and the Flying Spot Readout approach. Other unique components were designed (e.g., Film Processor, Film Transport, Pictorial Scanner/Recorder, Microfiche Transport and Transfer Submodule, Microfiche Duplicator) while still other components were identified as being available (with noted modifications) to serve as building blocks of the Information Processor.
