ABSTRACT:
A near-filed optical storage technique based on the “second surface” recording, where the optical storage medium is designed to have the recording layer formed between the reflective layer and the optically transparent substrate, and optical head and the medium maintain the near-filed configuration to achieve a numerical aperture greater than unity at the recording layer.
