Abstract

The recording mechanism of an organic dye based CD-R disc has been studied by many researchers.^1~4) Based on their studies, three different deformation effects, a bump at the dye/PC interface, a pit in the dye at the dye/Au interface and a bubble at the dye/Au interface are generally accepted as the recording mechanism of CD-R. Even though they predicted the deformation effects by the thermal analysis and observed the effects experimentally by using various microscope techniques qualitatively, the relationship between the deformations and the recording characteristics has not been studied quantitatively.
