Abstract: A method of producing a magnetic recording medium, and an apparatus thereof in which coercive force can be detected in an in-line mode, a metal thin film magnetic layer can be produced stably, and a vapor deposition film having a stable quality can be obtained. A method of producing a magnetic recording medium, comprising the steps of forming a metal thin film magnetic layer on a substrate, irradiating a light to a surface of the metal thin film magnetic layer, and measuring lightness of a reflected light from the surface to monitor coercive force of the metal thin film magnetic layer.
