An optical information recording and reproducing apparatus comprises a reproduction signal processing circuit including one or more elements that have respective variable parameters for changing the respective states of the elements at the time of read-out of data from a recording medium, whereby the data is read out from the recording medium by changing the states of the elements. The result is a reduction in read-out errors and hence an increase in the reliability of the apparatus.
L'invention est un appareil d'enregistrement et de lecture optiques d'informations qui comprend un circuit de traitement de signaux lus comportant un ou plusieurs éléments ayant des paramètres variables respectifs utilisés pour modifier leurs états respectifs au moment de l'extraction des données d'un support d'enregistrement, dans lequel cette extraction est effectuée en modifiant les états de ces éléments. Il en résulte une réduction des erreurs d'extraction et, par conséquent, une amélioration de la fiabilité de l'appareil de l'invention.
