A Small High-Performance Videotape Recorder For Military Airborne Applications

The INSTAVIDEO*recorder was designed and developed as a rugged, portable video recorder for both color and monochrome for the industrial and educational markets. Figure 1 shows the recorder/reproducer portion of the system, and Figure 2 shows it with the cover removed. Recent tests suggest that the machine will operate well in airborne applications. Specifically, it offers low time-base error over wide ranges of temperature, vibration, and acceleration in all attitudes, uses I/2-inch tape on a self-threading reel, can be supplied from batteries or power, and weighs only 17.6 pounds, exclusive of power pack. The present design incorporates both record and playback electronics in the same unit, but substantial advantages could be derived by separating the record unit from the play back system. The latter approach would allow bandwidth extension to 6 MHz from the present 2.7 MHz at -3 dB) at a 43-dB peak-to-peak signal to-rms-noise ratio. However, extension to 3.5 MHz is possible without significant design change.
