Abstract
Tête magnétique réalisée suivant la technique des couches minces et dans laquelle le matériau magnétique électriquement conducteur du noyau est bobiné directement plusieurs fois autour d'un conducteur électrique qui assure l'excitation de la tête. Etant donné que de la sorte cette tête ne nécessite pas l'emploi de couches isolantes entre le matériau du noyau et le conducteur, la fabrication de la tête peut avoir lieu exclusivement par des techniques de galvanisation. Application : appareils d'enregistrement et/ou de reproduction.
