  • Cobalt base alloy as protective layer for magnetic recording media
    Patent number: 4079169
    Abstract: A magnetic recording media is manufactured by depositing a nonmagnetic cobalt base alloy onto a substrate preferably aluminum as a protective layer for the substrate. The cobalt alloy includes chromium, tungsten, and nickel. The clad protective layer can be deposited in several steps with or without a polishing between the deposition steps to provide better corrosion protection for the substrate and covers surface imperfections of the substrate. The cobalt alloy is preferably sputtered onto the prepared substrate.
