Latest Patents

Ebinuma holds 1 patent for his invention titled "Optical information medium with sample mark area and multiple." This optical disc consists of a base plate, a reflective thin layer, and a protective thin layer. The design features a sample mark area with two sample marks, strategically offset on either side of a track. These sample marks are produced using an injection molding technique that incorporates a replica method. During the injection molding process, additional pressure is applied to the soft injected plastic resin, resulting in double transcription of the sample marks. To prevent this double transcription, groove areas are included on opposite sides of the sample mark area, providing an anchor effect during the injection molding process.
