SUPPORT D'ENREGISTREMENT REVERSIBLE PAR STOCKAGE OPTIQUE D'INFORMATIONS, PROCEDE D'ENREGISTREMENT REVERSIBLE SUR UN TEL SUPPORT. |
摘要 |
A reversible recording medium based on optical storage of at least one item of information within a support material, includes at least one layer of support material having: base molecules able to take, in a local zone, a first collective state of molecules able to generate a first signal of second harmonic characteristic of this first collective state of molecules when excited by electromagnetic reading radiation; the base molecules having the first collective state of molecules able to transform, at least in part, into transformed molecules so as to pass to a second collective state of molecules when excited by electromagnetic writing radiation, the molecules having the second collective state of molecules able to generate a second signal of second harmonic characteristic of this second collective state of molecules when excited by the electromagnetic reading radiation. The molecules exhibit a molecular structure based on a coumarin skeleton of Formula (I). |
