  • Abstract
    Amorphous video heads have been developed by a novel process of head fabrication. The process is simple and enables to fabricate the head with narrow track width(10-24μm) and narrow gap length( \\simeq 0.2\\mu m). The heads are made of Fe4.7Co70.3Si15B10amorphous ribbon and have such a structure that the track width of the head is coincided with the thickness of an amorphous ribbon. Twin roller quenched ribbons are shown to be most suitable for the amorphous video head. Using these heads, the output signal for metal tape (Hc;1450 Oe, Br;2500G) is 14dB larger than the output for Cro2tape(Hc;700 Oe, Br; 1500G) at 5MHz (3.45m/s relative speed). Furthermore, it is shown that the heads can record on the Hc; 1700 Oe metal tape effectively.
