摘要:
There is disclosed an optical retrieval apparatus which uses a laser for illuminating an optical element. A sensor responds to modulated light from the optical element to produce electrical signals. The optical element has a substrate and on the surface of the substrate, a dye containing recording layer and a light reflecting layer. The improvement is that the dye is a leuco dye.
