Abstract

A találmány tárgya eljárás információjelnek (10) adott rögzítésisebességgel való rögzítésére adathordozó (30) információs rétegén(30), ahol az információs réteget (301)egy sugárnyalábbal (32)megvilágítják, és az információs réteg (301) egy első és egy másodikfázis állapot között megfordíthatóan változtatható. Az eljárás soránaz információjelet (10) a sugárnyaláb (32) alkalmazásával rögzítik azinformációs réteg egy első területén, ezzel egy jelet hoznak létre azinformációs rétegen (301) az első fázis állapot előidézésével. Azinformációs réteg (301) egy második területén, a jel előtt és után,egy impulzusos sugárnyaláb (32) alkalmazásával törlő lépést hajtanakvégre, amellyel az információs rétegen (301) a második fázisállapototidézik elő. Az impulzusos sugárnyaláb (32) olyan törlő impulzusokattartalmaz, amelyek egy törlés energiaszinttel és egy előfeszültségenergiaszinttel rendelkeznek a törlés impulzusok között, ahol azelőfeszültség energiaszint a rögzítési sebességtől függő. A találmánytárgya továbbá az eljárás foganatosítására szolgáló berendezés. Ó
