Title: Production of magnetic recording medium
Inventor: SUGITA RYUJI
IPC: G11B5/85
Filed: 1988-02-15
Abstract: PURPOSE:To stably produce a perpendicular magnetic recording medium without wrinkling the medium by adjusting the quantity of the moisture particles to be included in a substrate to the quantity smaller on the side where a magnetic layer is formed than on the other side at the time of forming the magnetic layer consisting of a Co-base alloy. CONSTITUTION:A heating roller 8 is in contact with the surface side (the surface on which the magnetic layer is formed) of a high-polymer film. The water molecules contained in the surface side of the high-polymer film are removed by passage of this roller. The water molecules are emitted from the rear face (the surface in contact with the peripheral face of a cylindrical can 2) of the high-polymer film after the high-polymer film 1 starts contact with the cylindrical can 2 before the vapor deposited film is formed at the time of vapor deposition and, therefore, the wrinkling is prevented. Since the water molecules are hardly emitted from the front face of the high-polymer film at the time of the vapor deposition, the crystal orientability of the Co-base alloy is not deteriorated. The perpendicular magnetic recording medium having the excellent magnetic characteristics is thus obtd.
