ABSTRACT:
A process improvement is disclosed for use in the matrixing process employed in the manufacture of molded records. In accordance with the disclosure, a narrow texturized band is provided in either the outer or inner unrecorded areas of a matrix or in both areas of a matrix, so that when a replica is electroformed on the matrix the texturized bands will provide sufficient additional grip of the replica to the matrix to prevent premature separation.
