Abstract
An optical information memory medium, including, in the stated order a substrate, an optical information memory layer which is capable of memorizing information therein, and a reversible display recording layer which is capable of rewritably recording therein, in a visibly recognizable form, at least part of an information corresponding to the information memorized in the optical information memory layer, and a display recording method using the optical information memory medium are disclosed.
Claims75
An optical information memory medium, comprising, in the stated order:
- (a) a substrate,
- (b) an optical information memory layer having information memorized therein, and
- (c) a reversible display recording layer having a side facing away from said optical information memory layer and having rewritably recorded therein, in a form that is visibly recognizable on said side, at least part of an information corresponding to said information memorized in said optical information memory layer.
A display recording method, using an optical information memory medium, comprising, in the stated order:
- (a) a substrate, (b) an optical information memory layer which is capable of memorizing information therein, and (c) a reversible display recording layer having a side facing away from said optical information memory layer and capable of rewritably recording therein, in a form that is visibly recognizable on said side, comprising the steps of:
- memorizing and/or rewriting information that can be optically read by applying a laser beam thereto in said optical information memory layer, and
- recording and/or rewriting, in said reversible display recording layer, at least part of an information corresponding to said information memorized in said optical information memory layer in a visibly recognizable form.
