Abstract:
1. An optical disc lamination apparatus comprising a spinner apparatus for spreading an adhesive on a surface area between a first substrate and a second substrate on which a recording layer is formed on at least one of said substrates, and further comprising a curing apparatus that cures said adhesive by irradiating said adhesive with ultraviolet rays through said substrates; wherein, said curing apparatus comprises a semiconductor light-emitting apparatus, comprising a plurality of light-emitting semiconductor elements arranged substantially in concentric circles at nearly constant intervals or in close mutual proximity over the surface area containing said adhesive, arranged at a prescribed distance from said adhesive, wherein said adhesive is cured by sequentially emitting ultraviolet rays on a time delay from an innermost concentric circle to an outermost concentric circle.
