Process for producing a magnetic recording medium.

摘要

A process for producing a magnetic recording medium comprises heating a crucible (11) containing a ferromagnetic material (17) in a high vacuum (2) corresponding to a pressure of 8 x 10<-><4> torr or lower thereby vaporizing the ferromagnetic material (17), impinging accelerated electrons from an electron radiation source (12) against the vapor particles to ionize them, and accelerating the resulting ionized vapor particles in an electric field (14) and impinging them against a substrate (5) composed of a non-magnetic material to form a ferromagnetic thin film thereon.
