Abstract

Dispositif de repérage automatique de séquences d'enregistrement analogique sur support magnétique multipistes, tel qu'une bande. Le dispositif comprend des roues codeuses 3 pour élaborer manuellement un signal numérique de code affecté à chaque séquence, des moyens d'écriture 4 de ce signal de code sur une partie d'une piste de la bande 1, des moyens de lecture 7 et d'affichage 10, du signal de code écrit ou lu sur la bande, et un étage de commande 12 pour la sélection lecture-écriture. Application au repérage rapide de l'enregistrement analogique sur bande magnétique, de résultats de tests médicaux tels qu électro-cardiogrammes ou électro-enréphalogrammes.
