光ディスクの製造方法および装置
Document Type and Number:
Japanese Patent JP3958802
Kind Code:
B2
Abstract:
Substrates to be paired are alternately aligned. One substrate of a pair of substrates adjacent to each other is turned over thereby to face the other substrate, and the substrates held in a state facing each other are sent to a bonding position. An adhesive is supplied annularly into an interval of the substrates, and the substrates are rotated in a planar direction to thereby narrow the interval and eventually spread the adhesive in a radial direction to form an adhesive layer. The lower substrate is supported from below and carried from the bonding position to a setting position, and the adhesive layer is set, whereby an optical disk is obtained. The optical disk is taken out from the setting position.
