Paper Abstract

A new cyanine dye thin film has been prepared for high-density digital versatile disc-recordable (DVD-R) by means of a spin- coating process. The effects of the optical and thermal properties of the cyanine dye on the recording characteristics were studied. Rapid decomposition of the cyanine dye in a narrow temperature range, which is critical to the clear mark edges, is shown in this paper. A steep absorption edge at the 635 nm is crucial to high reflectivity. The optical recording performance of the cyanine dye thin film shows that high reflectivity contrast (48%) can be obtained at low writing power and narrow writing pulse-width using He-Ne laser (632.8 nm) irradiation. The carrier to noise ratio (CNR) of the single layer disk is greater than 40 dB at the traveling rate of 2.4 m/s.
