Beschreibung
Zusammenfassung:	PURPOSE:To obtain a high-density recording medium having excellent running property and good winding style by providing an intermediate layer contg. polyether acrylate having a specific mol.wt. or below and radiation polymerizable monomer at a specific proportion between a non-magnetic substrate having surface roughness of a specific value or above and a magnetic layer. CONSTITUTION:A paint contg. polyether acrylate having =0.01mu surface roughness and a magnetic layer such as a thin ferromagnetic metallic film or the like. Electron rays, UV rays, etc. are irradiated thereto after coating to form the intermediate layer having
