Zusammenfassung:A production method of and a production apparatus for an optical recording disc comprising two bonded round substrates, capable of obtaining a high quality optical recording disc by drastically reducing the number of bubbles remaining in a cured ultraviolet ray curing type resin of the completed optical recording disc. An adhesive is applied on a predetermined position of the upper surface of a first round substrate. The first round substrate applied with the adhesive is reversed. The reversed first round substrate and a second round substrate are bonded with each other via the adhesive on the first round substrate.
