Abstract

PURPOSE: To manufacture the recording medium excellent in the magnetic characteristics, by the constant incident angle of vapor-deposited metal, through the vapor deposition of the ferromagnetic metal on the tape support while guiding with the guide surface of specific shape.
CONSTITUTION: To the tape support S fed from the reel 2 and wound on the reel 3 (hereinafter, simply called tape), during the carriage at the tape guide 7, the ferromagnetic metal M is vapor-deposited from the evaporation source 0 within the range of angle DOC to manufacture the magnetic recording medium. In this case, on the curve determined by the variables r and ϕ satisfying the relation indicated with equation [where; r is the distance of radiated straight line of the metal M, θ is the crossing angle between the radiated straight line and the tape S, and r0 is the distance (constant) of the radiated straight line at ϕ=0], the tape S is guided, through the setting of the shape of the surface of the tape guide 7, allowing to adhere the evaporated metel on the surface of tape S with a given angle θ.
