ABSTRACT:
An optical disk includes a pair of disk substrates and a recording layer on at least one substrate, the disk substrates being mated by bonding the substrates at their inside surfaces through an adhesive layer such that the recording layer is internally enclosed. In one form, a pair of self-adhesive layers are applied to the respective substrate inside surfaces and formed with a plurality of channels extending over the surface from the outer or inner circumferential edge to the outer circumferential edge. The self-adhesive layers are bonded together to integrate the pair of disk substrates in which the channels form passages for allowing air escape. In another form, a pair of adhesive layers are applied to the respective substrate inside surfaces. The pair of disk substrates are joined by bonding the adhesive layers together through a buffer foam sheet.
