MAGNETIC DISC MANUFACTURING METHOD

摘要

A Co-Ni-P magnetic disc was manufd. by non-electrolytic alloy. Thus, magnetic Co-Ni-P disc was alloyed on the surface of the mixt. PET with Al to give a final product composed of --80-40% (Co/Co + Nix100%) and 1-2% phosphorous. 80% of (Co/Co + Nix100) showed 830 Oe and 8600 G, and 40% (Co/Co + Nix100) showed 810 Oe and 7000G).
