ABSTRACT:
A method of manufacturing a magnetic recording medium facilitates preventing a film inflation from occurring in an environmental condition range between −40° C. and 80° C. and an 80% relative humidity. The magnetic recording medium includes a plastic substrate and an undercoating layer on the plastic substrate. The undercoating layer is provided with a columnar structure, which prevents water (moisture) between the plastic substrate and the undercoating layer from aggregating and, therefore, the film inflation from occurring.
