Abstract:
A magnetic recording medium, which comprises an underlayer, a ferromagnetic thin film metallic layer and a protective film layer successively and continuously laminated on a non-magnetic resin substrate, where (A) at least one layer selected from the group consisting of an Si layer, an Si.sub.w N.sub.x C.sub.y O.sub.z layer (where w+x+y+z=100 at. %, w.gtoreq.30 at. %, O.ltoreq.z.ltoreq.50 at. % and x+y.gtoreq.20 at. %), and an Al.sub.w N.sub.x C.sub.y O.sub.z layer (where w+x+y+z=100 at. %, w.gtoreq.30 at. %, O.ltoreq.z.ltoreq.50 at. % and x+y.gtoreq.20 at. %), and (B) at least one layer selected from the group consisting of silicides, nitrides, oxides, carbides or their mixtures of Ti, Ta, Mo, V, Zr and their alloys are laminated on the non-magnetic resin substrate and in the order of (A) and (B) between the non-magnetic resin substrate and the underlayer.
