Title:
MULTILAYER RECORDABLE OPTICAL MEDIUM WITH FLUORESCENT READING
Document Type and Number:
WIPO Patent Application WO2001093258
Kind Code:
A3
Abstract:
In a multilayer recordable optical medium, each recording layer includes a luminophore (202) that fluoresces under reading laser light and a quencher (203) capable of quenching the luminophore fluorescence. Initially, the luminophore and the quencher are not intermixed, so that the default state of the luminophore is fluorescent. During writing, focused writing radiation heats a spot in the medium so as to cause the luminophore and the quencher to be intermixed, thereby quenching the fluorescence.
