摘要：The recording/reproducing quality of a multilayer optical information recording

medium deteriorate not only due to interference from other layers caused by lightconverging on other information layers but also due to stray light converging on thesurface of a protective layer and stray light that does not converge on other informationlayers but rather returns to an optical head through the same optical path as thereproducing signal. The thickness composition of intermediate layers (, and ) and theprotective layer () in a four-layer optical information recording medium are set so as toeliminate the influence of interference caused by stray light from other layers reflectedup to three times.
