Paper Abstract

A new technique for recording and retrieving small marks beyond the optical diffraction limit was recently proposed by Tominaga et al. Carrier to noise ratio (CNR) of more than 10 dB was demonstrated with an estimated recorded marks of 90 nm at a constant linear velocity of 2.0 m/s using a laser wavelength of 686 nm and a numerical aperture of 0.6.
