Abstract
PURPOSE: To obtain a magnetic recording medium superior in resistance to wear, magnetic characteristics, etc., by vapordepositing a ferromagnetic body, including cobalt, on a base of non-magnetic material in a cluster ion-beam vapor-deposition method.
CONSTITUTION: On a base of non-magnetic material (polyethylene terephtalate, glass, etc.), a ferromagnetic substance (preferably, cobalt chromium alloy of not greater than approximately 25wt% in chromium content rate) containing cobalt is vapor-deposited in the cluster ion-beam method, thereby forming a vapor-deposition value of approximately 0.05W10μ in thickness. Further, cluster ion-beam vapor deposition is carried out, preferably, at a vacuum degree of approximately 10-3W10-8Torr and with an electric field acceleration voltage of approximately -0.1W-15kV.
