Abstract

Continuous efforts have been made to increase the recording density of optical memories because of the ever growing demands for high-speed and large data computing as well as for high-quality video recording. Super resolution disk technologies such as magnetically induced super resolution (MSR), which is one of the practical approaches, require a mask layer which shows a nonlinear response to the light intensity. Super resolution technique using photon-mode photochromic organic dye is expected to be applicable to any kind of recording layer, e.g., read-only, magnetooptical, phase change and so on, since the mask layer's response is independent of the recording layer and the mask layer is capable of high sensitivity. This paper presents a discussion on a super resolution disk with a photochromic mask layer.
