Multichannel Magnetic Film Recording and Reproducing Unit

The multichannel magnetic film recorder and reproducer provides three 200-mil tracks in accordance with proposed ASA standard for 35mm film. The effective crosstalk between adjacent tracks approximates −60 db and flutter content does not exceed 0.05%. Complete recording and reproducing transmission equipment is housed in the recorder and associated base cabinet. The recording channels operate from a nominal input level of −30 dbm, and a reproduced output of +16 dbm is obtained from each of the reproducing channels. Monitoring of each channel is provided from a separate triple-track head.
