摘要:
In an optical recording method which utilizes hole burning, a plurality of sorts of light absorption centers having different properties are caused to coexist or to exist in the form of layers, thereby to remove the problem that, although the multiplicity of recording is high, the spacial recording density is low, so the overall recording density is low. Accordingly, the present invention can provide an optical recording method of very high recording density.
