ABSTRACT:
A vertical magnetization recording medium is formed on a high polymer film substrate by vacuum deposition of Co-Cr film or deposition of Co-Cr film with preceding deposition of permalloy film, both with Ti-vacuum deposited interface film on the substrate face, whereby vertical orientation of the C-axis of Co-Cr film with respect to the film surface is easily obtainable, thereby assuring good characteristic as vertical magnetization recording medium.
