Abstract:
An apparatus for re-surfacing digital information bearing discs of the type having a central opening and having a protective surface on one side overlying an annular information layer extending part way from the edge of the disc toward the central opening, said apparatus comprising:(a) a cabinet having side walls and defining a lower compartment and an upper processing compartment;(b) first and second motors located in said lower compartment, said first motor having a generally vertically extending first shaft and said second motor having a generally vertically extending second shaft, said first and second shafts being disposed in parallel spaced-apart relationship and being rotatable in opposite directions at approximately the same rotational speed;(c) said first shaft having mounting means thereon for mounting a disc in a generally horizontal position with the protective surface to be re-surfaced disposed downwardly and the opposite surface upwardly disposed;(d) an arbor on said second shaft supporting a resilient pad in overlapping relationship with the protective surface of said disc, said resilient pad having a surface which removably receives an abrasive material, said arbor and abrasive material being selected to extend in overlapping relationship only across the annular information layer; and(e) said mounting means being axially adjustable to maintain substantially planar contact between the disc and abrasive material.
