A helical scan, high bandwidth tape recorder, Model V-305, is being developed for hostile environmental applications, such as airborne reconnaissance. The V-305 has the capability of recording and reproduction on a single asynchronous analog channel with a minimum bandwidth of 12 MHz. The data will be recorded in analog form on a 1/2 inch format tape cassette. In addition, it has selectable/analog auxiliary channels and a 20 kHz analog channel. Control of the recorder is performed via MIL-STD-1553A/B and RS-422-A.
