Abstract :
The authors have developed a metal evaporated (ME) tape for use with the high-band 8-mm video system. Compared to conventional metal particle tape, the ME tape has significantly improved electromagnetic characteristics, with a video output of +5 dB and a video carrier-to-noise ratio of +5 dB. Its overall reliability equals that of conventional coated tape. The evaporation process is described, the characteristics of the tape surface are presented, and the back coating and surface treatment are discussed
