Abstract
The optical disc of the present invention includes a first translucent substrate having generally planar opposed top and bottom surfaces. The bottom surface is smooth and adapted to an optical beam for accessing data on the disc. The top surface of the first substrate has formed pits that represent data recorded on the disc. A reflective coating is formed on the top data surface of said first substrate to enable the top surface to reflect light back to an optical reader. A bonding agent is disposed over the reflective coating and a second substrate is bonded to the first substrate thought hot melt bonding. The second translucent substrate has a top surface incorporating a plurality of lenticules formed therein, and a bottom surface having an interlaced segmented lenticular image printed thereon. The method of the present invention provides that the top substrate incorporating lenticular imagery is hot melt bonded through use of a bonding agent to a bottom substrate bearing recorded data and a metalized layer for reflecting optical beams.
