PURPOSE:To increase the fixing strength and also to relax the limit of an adhesives by arranging inside and outside spacers of ring form while opposing information recording layers of a disc transparent base, inserting a wire at an air gap opposite to the recording layer and packing the adhesives so as to fix the base. CONSTITUTION:The ring form inside and outside spacers 7, 9 are arranged while opposing the information recording layers 5, 6 of a couple of the transparent bases 1, 2 having center holes 3, 4. The inside and outside wires 11, 12 adhered with the adhesives are inserted to the air gap opposite to the recording layers 5, 6, the adhesives 8, 10 are packed and cured so as to fix the bases 1, 2. Since the wires 1, 2 are inserted, the thickness of the adhesives 8, 10 is made thin, the fixing strength is increased and also the moving of the adhesives 8, 10 to the outside is prevented by surface tension. |
