Abstract
PURPOSE: To obtain a good aluminium alloy substrate used as a magnetic disc, by blocking the electricity supply hole, which exists in the anodic oxidation film formed on the aluminium alloy substance, by nonmagnetic materials.
CONSTITUTION: Nonmagnetic materials used for filling-up of the electricity supply hole are a metal, a metal alloy, or a metal oxide. The electricity supply hole can be filled up with metals or metal alloys such as Cu, Au, Ag, Rh, Ni-Mo and Ni-P by the electroplating method or with metal oxides by the electrophoresis method. After the electricity supply hole of the anodic oxidation film is filled up in this manner, a thin film with Fe3O4 or γ-Fe2O3 as main components is formed on the anodic oxidation film by vapour or sputtering, and further, this film is subjected to reduction and oxidation processings at approximately 200°C, thereby forming an indefectible film with γ-Fe2O3 as main components.
