PURPOSE:To obtain the forming structure of a protection film without generating a peeling phenomenon by forming a resin coat film of hot-melt material on the upper plane of a recording layer. CONSTITUTION:The resin coat film 5 of hot-melt material is formed on a dielectric protection film 22 by a roll coater. And the film 5 functions as the protection film, therefore, superior adhesiveness can be obtained and the recording layer can be prevented from being deteriorated. Also, a dielectric film 21 and a magnetic film 3 are formed on a transparent substrate 1, which form the recording layer. |
