Method for preparing magnetic recording medium

摘要

A method of preparing a ferromagnetic recording medium is disclosed. The method includes charging a ferromagnetic material in an evaporator. The material is then irradiated with an electron beam having a beam current density of at least 0.1 A/cm2 in order to evaporate the material. The evaporated material is vapor deposited on a continuously travelling support in order to from the recording medium. The vapor deposition type magnetic recording medium produced has good metal film adhesion and durability.
