<p>A process for manufacture of a second surface optically recordable disk having ultraviolet (UV) inhibiting characteristics is disclosed. A reflective laminate sheet of aluminum, superimposed on a glass laminate substratum, is flow process produced by pyrolysis and precipitation of a layer of aluminum from gasified triisobutyl aluminum onto a laminate web of silicate (amorphous glass) which is concomitantly pyrolized from tetraethoxy silane, with or without alkoxide additives, and precipitated upon a flowing body of molten tin to form a dual laminate sheet. To complete the process, an optically active layer which is applied over the reflective layer is embossed with optically transparent ultraviolet (UV) inhibiting polycarbonate, protective covers, the mating surfaces of which, maybe, pregrooved and coded to form second surface optically active media. Covers with bonded laminates are then successively severed from the laminate sheet to yield independent second surface optically recordable media. <IMAGE></p> |
