METHOD FOR SPREADING ADHESIVE IN OPTICAL DISC

摘要

A method for spreading an adhesive (normally, UV-curing resin) capable of spreading an adhesive between two disc substrates with uniform film thickness in a process for pasting an optical disc. A method for spreading an adhesive in an optical disc which spreads the adhesive (R) by interposing the adhesive R between two disc substrates (D1, D2) having a central hole and rotating the disc substrates, wherein upper surface at the outer circumferential end part of the disc substrate is pressed when the adhesive is spread. The upper surface at the outer circumferential end part of the disc substrate is pressed by blowing air.
