Abstract (en)
[origin: WO8912886A1] There is described a method and apparatus for magnetic recording wherein the signal to be recorded is modified in inverse proportion to the transfer function of the recording process. In addition, the harmonics of the modified signal are subjected to phase advance in relation to their frequency.
Abstract (fr)
On mis au point un procédé et un appareil d'enregistrement magnétique modifiant le signal à enregistrer dans la proportion inverse à la fonction de transfert du processus d'enregistrement. De plus, les harmoniques du signal modifié sont soumises à l'avance de phase par rapport à leur fréquence.
