Abstract

La présente invention concerne un lecteur de disque comportant un actionneur (3) portant une tête (5) et pourvu d'un bras de contact (45), et un levier de blocage par inertie (11) placé rotatif à proximité de la partie périphérique externe d'un disque (2) tout en exerçant un contrepoids continu, ce levier comportant un crochet (43) pouvant s'accoupler avec la branche (45) de l'actionneur (3). Le crochet (43) du levier de blocage par inertie (11) s'accouple avec le bras (45) de l'actionneur (3) en période de repos. Lorsque le lecteur de disque est activé, le levier de blocage par inertie (11) est mis en rotation par le flux d'air produit par la rotation du disque (2) pour relâcher le crochet (43) du bras (45).
