发明名称 PROCESS FOR MAKING DISCS
摘要 <p>The manufacture of information carrying discs has required relatively slow processing because of the need to conform materials to exact mold shapes and to remove entrapped gases. The use of either preformed films or liquids provides different degrees of this problem. The use of a process whereby a bead of photopolymerizable liquid is moved across the mold surface has been found to accurately fill the mold, remove air bubbles, and enable rapid replication of information carrying discs.</p>
