ABSTRACT:
A process for manufacture of a second surface optically recordable disc having ultraviolet (UV) inhibiting characteristics is disclosed. A reflective lamina of aluminum, superimposed on a glass lamina substratum, is flow process produced by pyrolysis and precipitation of a lamina of aluminum from gasified triisobutyl aluminum onto a lamina 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 composite lamination sheet. To complete the process, an optically active lamina which is applied over the reflective lamina is embossed with optically transparent ultraviolet (UV) inhibiting polycarbonate, protective covers, the mating surface of which, may be, pregrooved and coded to form second surface optically active media. Covers with bonded lamination are then successively severed from the laminated sheet to yield independent second surface optically recordable media.
