Apparatus for manufacturing rigid computer memory disc substrates

摘要

A method and an apparatus for manufacturing rigid computer memory disc substrates is disclosed wherein the apparatus comprises a circular base plate, the base plate being mounted horizontally for rotation about a vertical axis; a plurality of spindles rotatably mounted on motors mounted on the base plate, the spindles extending radially outwardly from the base plate, in equally spaced relationship therearound, the outwardly extending end of each spindle including a fastening means for mounting a rigid disc to be processed thereon; a plurality of work stations spaced around the circular base plate for performing work operations on the discs; and a motor for rotating the base plate so as to convey each of the discs consecutively to each of the work stations.
