Abstract

L'invention concerne un procédé d'asservissement radial et un dispositif de reproduction le mettant en oeuvre pour disques optiques. Dans une tête optique de dispositif de reproduction classique utilisant un détecteur quatre-quadrants à quatre photodiodes réparties de part et d'autre d'une direction parallèle à l'axe de la piste, les signaux individuels des photodiodes (d1 à d4) sont combinés pour obtenir, par différence (21, 22), des signaux de lecture selon les deux diagonales (diag1, diag2). Un circuit de comparaison en phase (100) permet, par mesure du déphasage des signaux de lecture de diagonales, d'élaborer un signal d'erreur radiale (Sr). L'invention s'applique notamment aux disques de phase à marques faiblement déphasantes.
