ABSTRACT:
The objective of the present invention is to provide a method of fabricating a thin film magnetic recording medium where excellent read/write characteristics and high productivity are obtained and also to provide the thin film magnetic recording medium. The present invention is a method of fabricating a thin film magnetic recording medium where vapor evaporation is given by a vacuum evaporation device onto a traveling substrate to form a magnetic layer. The temperature of a reevaporation member, disposed so as to be opposed to the substrate on the downstream side of a magnetic layer formation start portion where the magnetic layer begins to form, is raised to higher than the melting point of an evaporation material. Atoms, which are evaporated from an evaporation source and reach said reevaporation member for forming said magnetic layer, are reevaporated by the raised temperature of the reevaporation member. The atoms reevaporated and atoms evaporated directly from said evaporation source are mixed together and then the mixed atoms are caused to reach said substrate at the same time to form the magnetic layer.
