  • Apparatus for removal of a data carrier disk after molding
    Patent number: 4588369
    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.

  • Process for obtaining a copy disk from an original recording carried by a matrix
    Patent number: 4452748
    Abstract: The invention relates to a process for obtaining information-carrying disks by moulding from a recorded matrix. The invention makes it possible to obtain a disk having a recording area and intact areas, which are separated by stop areas. The invention more particularly applies to the production of video disks and disks useable in information technology. It facilitates the installation of covers on the disks.
