Paper Abstract

A new structure of super resolution optical disk with organic dye for recording layer was proposed. By utilizing of Sb thin film for the mask layer, below-diffraction-limited marks on organic recording layer could be recorded and retrieved. The mark size as small as 120nm could be read out on the current dynamic tester of digital versatile recordable disc (DVD-R). The conditions of optical pickup head are 635nm of laser wavelength (l) and 0.6 of lens numerical aperture (NA). The carrier-to-noise ratio (CNR) from recorded marks of 200nm was more than 28.5dB at low readout power of 2mW and at a constant linear velocity (CLV) equals 3.5 m/s. The recording layer with modified composition owned high thermal stability and the readout durability was more than 6 X 104 cycles without any decreasing of CNR.
