    摘要： 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 or alternatively has a photo-reactive chemical formed thereon. A reflective coating is formed on the top data surface or photo-reactive chemical 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 though hot melt bonding or UV 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 or UV bonded through use of a bonding agent to a bottom substrate bearing recorded data and a metalized layer for reflecting optical beams.

    摘要： A glass substrate for a data recording medium is disk-shaped and has a circular bore at the center portion. At least one of an inner circumferential end surface and an outer circumferential end surface is smooth. The smooth surface is formed by exposing at least one of the inner circumferential end surface and the outer circumferential end surface of a glass disk to a laser beam. During laser machining, the end surface of the glass disk that is exposed to the laser beam is heated and melted. Therefore, minute cracks, formed on the end surface of the glass disk before the laser machining, are eliminated. As a result, the strength of the glass substrate is maintained without a chemical strengthening treatment. This eliminates disadvantages caused by the chemical strengthening step.
