光ディスク装置の光学収差安定化のための技術開発

抄録

Reducing aberration is a key point in improving the recording density of optical disks and stabilizing their recording and reproducing characteristics. To reduce aberration, the technological development approach of quality engineering was introduced, and from basic functional considerations, the adhesive used in optical heads was selected as a theme. Development of an adhesive based on the functional evaluation of shape fidelity and curability enabled a pioneering improvement project to be carried out at low cost, and succeeded in reducing aberration variation by about half.
