Abstract
PURPOSE: To improve the wettability and fluidity of magnetic coating and the uniformity of a coating film by removing a protective film right before use by preventing oxidation on the surface of a substrate and dust from sticking, by forming the protective film for the aluminum alloy substrate by a thermal-hardening resin solution in an unhardening or half-hardening state.
CONSTITUTION: To prevent surface oxidation and contamination while mirror- finished magnetic-disk aluminum alloy substrate 1 is stored before a magnetic coating film is applied, protective film 2 is formed by applying in a dipping or spraying method a coating obtained by dissolving unhardened or half-hardened thermal- hardening resin, such as epoxy resin and phenol resin, in an organic solvent. Right before its use, film 2 is wiped off with an organic solvent to form clean magnetic coating film 3. Thus, it is made possible to form and fix uniformly the magnetic coating on the surface with any need for a hard storing method and to polish the surface right before using.
