A small-format videotape recorder (VTR) using an 8mm metal tape cassette has been developed by Hitachi Denshi, Ltd. This new VTR is used in a combination system that is a compact, lightweight, high-performance camera/VTR for ENG/EFP. Luminance signal and time-division multiplexing (TDM) chrominance signal are recorded separately on two video tracks to achieve a high-density recording. Thus, a high resolution and a high signal-to-noise ratio (SNR) are obtained (luminance channel band of 4.5 MHz, chrominance channel band of 1.5 MHz, SNR of better than 48 dB). This article describes the recording techniques, the equipment, and their technical features.
