ABSTRACT:
A disk which carries information obtained by molding from a cut matrix is detached from the matrix by means of a gas jet injected between the disk and the cut matrix. The disk is maintained in contact with the matrix both at the periphery and at the center, means being also provided for limiting deformation of the disk while it is being removed.
