Abstract
A method and apparatus for manufacturing a magnetic recording medium uses a small-diameter insulating substrate. The apparatus includes a carrier for a special size of 3.5 inches for receiving a plurality of small-diameter insulating substrates. Seed layers are deposited on the substrates, then each substrate is rotated to shift the position of the substrate so that the movable claw contacts the deposited seed layer. A bias voltage is applied via the movable claw for subsequent deposition layers.
