摘要： PROBLEM TO BE SOLVED: To provide an optical memory manufacturing method capable of improving productivity and a yield. SOLUTION: The optical memory manufacturing method includes a laminating step, a joining step and a cutting step. In the laminating step, the prescribed number of core layers 13 and and clad layers 14 are alternately laminated between two resin films 15a and 15b, and an uneven surface part for information reproduction is formed on the top surface of the clad layers to form units 11. In the joining step, the units 11 are stacked vertically and joined by laser welding through a light absorbing resin layer 24 to form a unit stacked body 11a. In the cutting step, a laser light source 30 emits laser beams 30a to the unit stacked body 11a mounted on an XY stage 29, and laser cutting is applied to the unit stacked body 11a along cut lines 28 to cut out optical memories including an information area 23 in prescribed size. The cutting step is a dry process. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an optical memory capable of improving the reproducibility of recorded information by reducing curvature of an optical waveguide. SOLUTION: In a laminate 11, core layers made of resin and clad layers made of resin are alternately laminated, and an uneven surface part for information reproduction is formed on one interface between the core layers and the clad layers. A base body 13 is higher rigid than the laminate 11 and is fixed by an adhesive tape 12 so that the entire bottom surface of the laminate 11 may be in contact. The optical memory 10 composed of the base body 13 and the laminate 11 is housed in a case 30 provided with an opening 32 for regulating its external form and exposing a light introducing surface 19 and an opening 31 for exposing a scattered light emitting area 20. The base body 13 and the case 30 are made of plastic mixed with carbon black. Laser beams made incident on the core layers from the light introducing surface 19 are scattered by the uneven surface part and emitted from the scattered light emitting area 20.
