A magnetic recording medium having excellent durability and corrosion resistance as well as a magnetic recording device equipped with the magnetic recording medium is provided. The protective layer of the magnetic recording medium is composed of two layers, that is, a lower layer contacting with the magnetic layer and an upper layer on the lower layer. The internal stress of the lower layer is made smaller than that of the upper layer, and the surface free energy of the lower layer is made smaller than that of the upper layer.
