Abstract

L'INVENTION CONCERNE DES MOYENS POUR REDUIRE LES EFFETS DE PERTURBATIONS VERTICALES DE LA SURFACE DES DISQUES PHONOGRAPHIQUES QUI SONT DUES AUX IMPERFECTIONS DU DISQUE ET DE L'APPAREIL DE REPRODUCTION. SELON L'INVENTION, UN TRAJET DE REFERENCE, CONSTITUE PAR EXEMPLE PAR L'ESPACE INTERSILLON DU DISQUE OU PAR UN SILLON BLANC, EST DETECTE DIRECTEMENT OU INDIRECTEMENT, AVEC OU SANS CONTACT, AU VOISINAGE IMMEDIAT DE LA POINTE DE LECTURE 44 ET EST UTILISE POUR COMMANDER L'APPAREIL MECANIQUEMENT, ELECTRIQUEMENT OU ELECTRONIQUEMENT DE FACON A SUPPRIMER LES EFFETS SUR LE SIGNAL REPRODUIT DES DEVIATIONS VERTICALES DU DISQUE 9. APPLICATION AUX APPAREILS PHONOGRAPHIQUES STEREOPHONIQUES A HAUTE FIDELITE.THE INVENTION CONCERNS MEANS FOR REDUCING THE EFFECTS OF VERTICAL DISRUPTIONS ON THE SURFACE OF PHONOGRAPHIC DISCS WHICH ARE DUE TO IMPERFECTIONS OF THE DISC AND OF THE REPRODUCING APPARATUS. ACCORDING TO THE INVENTION, A REFERENCE PATH, FOR EXAMPLE CONSTITUTED BY THE INTERSILLON SPACE OF THE DISC OR BY A WHITE TRAIL, IS DETECTED DIRECTLY OR INDIRECTLY, WITH OR WITHOUT CONTACT, IN THE IMMEDIATE NEIGHBORHOOD OF READING POINT 44 AND IS USED TO OPERATE THE MECHANICALLY, ELECTRICALLY OR ELECTRONICALLY SO AS TO REMOVE THE EFFECTS ON THE REPRODUCED SIGNAL OF THE VERTICAL DEVIATIONS OF THE DISC 9. APPLICATION TO HIGH-FIDELITY STEREOPHONIC PHONOGRAPHIC DEVICES.
