<p>An adhesive agent is applied to both single plates, upper and lower, in which case the formation of bubbles is minimized by using a specified application manner. A method of laminating optical disks (D) comprising the steps of placing a lower disk single sheet (D1) on a turntable (1), applying an adhesive agent (R1) in doughnut form to the lower disk single sheet (D1), placing an upper disk single sheet (D2) on another turntable (2), applying an adhesive agent (R2) in doughnut form to the upper disk single sheet (D2), placing the upper disk single sheet (D2) on the lower disk single sheet (D1 ) , and spreading the adhesive agent (%2) between the two disk single sheets by rotating the turntables. Since bubbles hardly enter the adhesive agent, the bubble content of the adhesive agent after spreading is very small, and even after the curing subsequent to ultraviolet ray radiation, the air content of the optical disk can be minimized, the quality being high. <IMAGE></p> |
