发明名称 OPTICAL RECORDING MEDIUM
摘要 <P>PROBLEM TO BE SOLVED: To provide an optical recording medium which is reliable in storing at a high temperature/humidity, stably operates at a high temperature with excellent mechanical properties and is capable of high speed reproducing and recording with high productivity. <P>SOLUTION: This optical recording medium has a base plate, a 1st protective layer, an optical recording layer containing Sb of 69-90 at% , a 2nd protective layer, a light reflector layer containing Ag of 98 wt% in weight or more, and a resin protective layer and/or an adhesive layer, all sequentially provided in this order. Further, it has at least one layer out of a 1st interface layer between the 1st protective layer and the recording layer, a 2nd interface layer between the recording layer and the 2nd protective layer, and a 3rd interface layer between the 2nd protective layer and the light reflector layer. And the film thickness of the 1st protective layer is 55&plusmn;10 nm, that of the optical recording layer is 9-14 nm, that of each of the 1st and 2nd interface layers is 2-7 nm, and that of the 3rd interface layer is 2-9 nm. <P>COPYRIGHT: (C)2005,JPO&NCIPI
