Abstract
PURPOSE: To reduce the amplitude of noise of recording body, by forming the evaporation film of nonmagnetic substance of high melting point as ground on the substrate and forming the vapor-deposited layer of magnetic metal or alloy corresponding to the ground layer.
CONSTITUTION: On the magnetic recording substrate 1 such as synthetic resin-made tape, the ground layer 2 is formed by evaporating the nonmagnetic substance of high melting point than magnetic metal or alloy, and on it, the magnetic metal layer 3 is formed by evaporating the specified magnetic metal or alloy with tilt injection. This ground layer 2 and the magnetic layer 3 are formed by corresponding a plurality of layers as objective. With this method, the crystal of vapor-deposited magnetic grain is made fine through the effect of the ground layer 2 and the effect of noise reduction can be obtained.
