TRANSFER DEVICE FOR DISC BASE PLATE

摘要

A disc base plate transfer device for duplication of the disc base plate (7) by transferring a pattern of projections and recesses on a stamper (10) onto a layer of a photopolymerization curable synthetic resin provided on a disc base plate (7) is disclosed. Air blowouts (62, 63) are formed in a centering pin (18) adapted for peeling the disc base plate (7) from the stamper (10) after the pattern on the stamper (10) has been transferred to the layer of the synthetic resin by photopolymerization curing of the resin. In this manner, dust and dirt may be prevented from remaining on the stamper (10) during peeling of the disc base plate (7), while the peeling of the disc base plate (7) from the stamper (10) is facilitated to prevent destruction of the disc base plate (7).
