Abstract
We calculated the conditions of surface plasmon resonance for various optical discs to evaluate the role of periodic lands and grooves or recording mark trains as grating couplers. With the typical parameters of structure used in the discs, it is shown that surface plasmons have a weak influence on ordinary optical discs. These results differ from the situation with super-resolution near-field optical structures where surface plasmons or localized surface plasmons have a considerable influence on such discs.
