Abstract

Az eljárás során egy előkészítő lépésben az adathordozóra jeleketvisznek fel úgy, hogy egy első teljesítménnyel rendelkezősugárimpulzusokkal lokálisan felhevítik az adathordozót, ezt követőenegy első méréssel meghatározzák a sugárimpulzusok egy másodikteljesítményét (Pmin), amely teljesítménynél az adathordozó optikaitulajdonságai az előkészítő lépésben felvitt jelek helyein alapvetőennem változnak meg, amikor az adathordozón a második teljesítménynélkisebb teljesítményű besugárzást alkalmaznak, és a normalizáltvisszavert teljesítmény növekszik, amikor az adathordozón a másodikteljesítménynél nagyobb teljesítményű besugárzást alkalmaznak. Egymásodik méréssel meghatározzák a sugárimpulzusok egy harmadikteljesítményét (Pmax), amely teljesítménynél az adathordozó optikaitulajdonságai megváltoznak, amikor az adathordozón az előkészítőlépésben felvitt jelek helyein harmadik teljesítményű (Pmax),besugárzást alkalmaznak, olyan mértékben, hogy a normalizáltvisszavert teljesítmény maximális lesz, ezt követően egyösszehasonlító lépésben meghatározzák az optimális törlőteljesítményt(PEO) a következő egyenletből: ahol a egy előre ismert állandó, és <egy változó, amely az adathordozó tulajdonságaitól függ. A találmánytárgya az eljárást foganatosító berendezés is. Ó
