Abstract

A találmány tárgya optikai adathordozó (20) adott hullámhosszúságúlézersugárral (10) rögzített törölhető felvételekhez, az adathordozó(20) egy alapból (1) és azon egymásra helyezett rétegekből (2) áll. Azegymásra helyezett rétegekből (2) kialakított rész tartalmaz egyrögzítő réteget (5), amely alkalmas arra, hogy állapota amorf éskristályos állapot között változzon, a rögzítő réteg (5) egy elsődielektromos réteg (4) és egy második dielektromos réteg (6) közöttvan elhelyezve; és egy fényelnyelő réteget (7), amely közvetlenül arögzítő réteg (5) mellett van elhelyezve. A fényelnyelő réteg (7) QRxképletű vegyületet tartalmaz, amelyben Q a Si, Ge, Ti, Zr, Hf, Nb ésTa elemek közül való egy elem, R az 0 és N elemek közül való egy elem,és amelyben a 0,8<Ac /Aa<1,50 feltétel megvalósításához 0<x<2,5, aholAc és Aa a rögzítő rétegnek a kristályos állapotú és az amorf állapotúterületekben elnyelt lézersugár mennyiséget jelölik egy 350-450 nmközötti hullámhosszúságú lézersugár esetében.
