ABSTRACT:
A method for making an optically readable medium containing a relief information track comprising the sequential steps of
(a) laminating a dry photohardenable film to a surface of a transparent dimensionally stable substrate;
(b) embossing the exposed surface of the photohardenable film with the relief information track by applying thereto under pressure a stamper die containing a reverse relief image of the information track;
(c) passing actinic radiation through the transparent substrate and the photohardenable film to effect hardening of the photohardenable film while it is contact with the stamper die; and
(d) separating the stamper die from the embossed photohardened film;
