Abstract:
A magnetic recording medium includes a support, a recording layer, and a protective layer provided on at least one surface of the support and containing plate-shaped particle powder. The plate-shaped particle powder is stacked in an overlapping manner in a thickness direction of the protective layer such that main surfaces of plate-shaped particles face a surface of the support, and the plate-shaped particles have an average plate ratio of 60 or more.
