Abstract: An apparatus for the electrolytic plating of computer memory discs comprising a plating container for the receipt of a liquid plating bath, a spindle fitted to the plating container, a prime mover connected to the spindle for causing relative rotational movement, a fixed and non-translatable stationary anode attached to the plating container, an electrical transmission system connected to the spindle and to the anode, and suitable current distribution controllers positioned within the plating container. The spindle has a receiving area for fixing to the inner diameter of a computer memory disc. The stationary anode is positioned on opposite sides of the receiving area of the spindle. The electrical transmission system includes a contact surface for establishing electrical contact with the edge of a computer memory disc. The current distribution controllers are adjacent the contact surface of the electrical conductors.

Abstract: An apparatus for electrolytic plating of computer memory discs comprising a plating container, a spindle, a prime mover, an anode, and an electrical transmission system. The plating container contains a liquid plating bath having a nickel compound included therein. The spindle is rotatably mounted to the plating container. The spindle has a section for receiving the computer memory disc radially. The prime mover is connected to the spindle so as to apply rotational energy to the spindle. The anode is fastened to the plating container generally adjacent and in plane parallel to the disc. Another anode is placed on the opposite side of the disc. The electrical transmission system is connected to the disc about the spindle and to the anode.
