Title (EN) TIMING ANALYSIS OF READ BACK SIGNALS IN MAGNETIC RECORDING DEVICES
(FR) ANALYSE DE SYNCHRONISATION DE SIGNAUX DE RELECTURE DANS DES DISPOSITIFS D'ENREGISTREMENT MAGNETIQUE
Abstract: front page image
(EN)Analysis of a read back signal in a magnetic recording device is disclosed. The read back signal is converted to a digital read back signal, and a low frequency component of the digital read back signal is restored. A sample clock is recovered from the restored digital read back signal, and the restored digital read back signal is averaged using the recovered sample clock. A timing error is calculated based at least in part on the averaged restored digital read back signal.
(FR)L'invention concerne l'analyse d'un signal de relecture dans un dispositif d'enregistrement magnétique. Le signal de relecture est converti en un signal de relecture numérique et une composante basse fréquence du signal de relecture numérique est restaurée. Un signal d'horloge d'échantillonnage est récupéré à partir du signal de relecture numérique restauré et le signal de relecture numérique restauré est moyenné au moyen du signal d'horloge d'échantillonnage récupéré. Une erreur de synchronisation est calculée au moins en partie sur la base du signal de relecture numérique restauré moyenné.
