ABSTRACT:
A mass production process for fabrication of a magneto-optic recording medium is disclosed. The process comprises alternately arranging first and second metal regions upon a target, installing isolating plates between adjacent regions, and moving a substrates over the target. When moving the substrates, a voltage is supplied to the target so that first and second metal regions alternatively deposit on the substrates in a continuous manner to form a multi-layer structure.
