Abstract

PURPOSE:To increase coercive force of magnetic tape and also make it satisfactory for audio by use of not only the vapor stream of 30 deg. or more but by effecting vacuum evaporation with evaporated vapor of a strongly magnetic material directed toward the substrate which moves on a cylindrical rotatory can.
