Title (EN) LONGITUDINAL MAGNETIC RECORDING HEADS WITH VARIABLE-LENGTH GAPS
(FR) TETES D'ENREGISTREMENT MAGNETIQUE LONGITUDINALES A ECARTEMENTS DE LONGUEUR VARIABLE
Abstract: front page image
(EN)A longitudinal recording head (50, 56, 60) for use with magnetic recording media includes a non-uniform gap (54, 59, 64) between first (51, 57, 61) and second magnetic (52, 58, 62) poles which focuses magnetic flux onto a small area of the magnetic recording medium. The non-uniform gap is preferably in the form of a cavity that is contoured to produce the desired flux pattern. Longitudinal recording heads incorporating the non-uniform gap are capable of improved recording densities.
(FR)La présente invention concerne une tête d'enregistrement longitudinale (50, 56, 60) destinée à un support d'enregistrement magnétique, qui comprend un écartement non uniforme (54, 59, 64) entre le premier (51, 57, 61) et le second (52, 58, 62) pôle magnétique qui concentre le flux magnétique sur une petite zone du support d'enregistrement magnétique. Cet écartement non uniforme a de préférence la forme d'une cavité profilée pour produire le schéma du flux souhaité. Des têtes d'enregistrement longitudinales comprenant cet écartement non uniforme peuvent améliorer les densités d'enregistrement.
