Title (EN) AUTOMATIC RESEARCH OF RECORDED SEQUENCES,PARTICULARLY ON CASSETTE RECORDERS
(FR) RECHERCHE DE SEQUENCES D"ENREGISTREMENT, NOTAMMENT SUR MAGNETOPHONE A CASSETTES
Abstract: front page image
(EN)A sensor (20) connected to a tape rewind spool (12) supplies pulses to a counter (23); a preliminary recording of digital marks is effected by a coding circuit (24) as a function of the evolution of the content of counter (23). Upon reading, a decoding is effected by the circuit (25) to control consequently the counter (23). During the sequence searching, a logic (28) controls as a function of the desired address a coarse preselection effected in fast motion by means of an estimation counter (26) initially filled with the content of counter (23), and is then up-dated from the output of the sensor (20). Then, a fine selection is effected in slow motion from the output of the recording decoding circuit (25). Application particularly to cassette recorder-readers.
(FR)Un capteur (20) lie a la bobine receptrice de ruban (12) fournit des impulsions a un compteur (23). Un enregistrement preliminaire de marques numeriques est effectue par un circuit de codage (24) en fonction de l"evolution du contenu du compteur (23). A la lecture, un decodage est effectue par le circuit (25), pour commander en consequence le compteur (23). Lors d"une recherche de sequences, une logique (28) commande en fonction de l"adresse desiree une preselection grossiere effectuee en defilement rapide a l"aide d"un compteur d"estime (26) rempli initialement par le contenu du compteur (23), et est mis a jour ensuite a partir de la sortie du capteur (20). Ensuite, une selection fine est faite en defilement lent d"apres la sortie du circuit de decodage enregistrement (25). Application notamment aux enregistreurs-lecteurs a cassettes.
