摘要： A method for manufacturing an optical disc and a method for transporting a multi-layered optical disc are provided. When adhering the sheet and the disc substrate, after the adhesive is supplied to the outer side of the groove on the disc substrate, the sheet is loaded on the disc substrate. The adhesive is pressed to extend to the groove. At this timer, because the surplus adhesive is blocked when flowing into the groove, the surplus adhesive does not overflow easily toward the inner side of the groove. In addition, even if the adhesive overflows toward the inner side of the groove the adhesive is kept between the non-adhered portion of the sheet and the disc substrate, preventing the adhesive from moving to the disc surface. The non-adhered portion is cut by the cutting blade after the adhesive is completely cured, and then removed from the disc substrate.
