Abstract
A recording system, using microfilm as the record medium, and consisting of a gas laser, an electrooptic modulator, and a photodetector has been investigated. Data are presented on the noise spectrum, linearity, frequency response, and error rate of this recording process. A machine which records 36 individual tracks on 8- mm wide microfilm has also been constructed and tested. Design considerations and operating performance of this machine are presented.
