Abstract
PURPOSE:To execute high-density recording and reproduction at high C/N under a wide range of use environment conditions by disposing a perpendicularly magnetized film on the surface of a heat-resistant-high-polymer film and disposing a thin film on another surface, then adhering the other high-polymer film onto this thin film. CONSTITUTION:The perpendicularly magnetized film 6 is disposed on the face A of the heat-resistant high-polymer film 5 and the thin film 7 is disposed on the other face B. The other high-polymer film 8 is adhered onto this thin film 7. The change of the heat-resistant high-polymer film 5 by moisture absorption is thereby substantially obviated. Namely, the heat-resistant high-polymer film 5 can be formed thin and, therefore, the influence that the film acts on the dimensional change over the entire part is decreased; in addition, said film is made into the structure sandwiched by the thin films 6 and 7, by which the moisture absorption from the outside is extremely minimized and the dimensional stability is improved. The C/N and drop-out are thus stabilized in the environment of a wide range.
