Abstract:
A method for producing an optical recording disc comprising the steps of:providing a first substrate and a second substrate; applying a resin on the first substrate; placing the second substrate in contact with the resin on the first substrate; spreading the resin between the first and second substrates to a predetermined thickness by: holding one of the first and second substrates fixed; rotating the other of the first and second substrates; and applying pressure to the first and second substrates; measuring the pressure applied to the first and second substrates; when the pressure applied reaches a predetermined value for obtaining a selected resin thickness, ending the rotating step and ending the applying step; and irradiating the resin to obtain the optical recording disc comprising the first and second substrates.
