Abstract
Cette invention concerne un dispositif de balayage optique permettant de balayer un support d'enregistrement optique (OD) à l'aide d'un objectif (12) pour concentrer un faisceau de rayonnement sur un point (18) sur une couche d'informations (3, 4) du support d'enregistrement (OD), lequel dispositif comprend notamment un système de correction optique (10) servant à modifier la vergence du faisceau de rayonnement et le degré d'aberration sphérique dans le faisceau de rayonnement en direction de l'objectif, la vergence et le degré d'aberration sphérique dans le faisceau de rayonnement pouvant être adaptés indépendamment.
