TETE MAGNETIQUE A FILMS MINCES POUR L'ENREGISTREMENT ET LA LECTURE D'INFORMATIONS AINSI QUE SON PROCEDE DE FABRICATION

LA TETE MAGNETIQUE SELON LA PRESENTE INVENTION COMPREND UN SUBSTRAT 10, UNE PREMIERE COUCHE MAGNETIQUE 11, UN ENROULEMENT CONDUCTEUR 13 ET UNE SECONDE COUCHE MAGNETIQUE 15, LADITE SECONDE COUCHE MAGNETIQUE DELIMITANT UN ENTREFER MAGNETIQUE A SON EXTREMITE ORIENTEE VERS LE SUPPORT D'ENREGISTREMENT ET ETANT COURT-CIRCUITEE MAGNETIQUEMENT AVEC LA COUCHE 11 A SON AUTRE EXTREMITE. LA SECONDE COUCHE MAGNETIQUE 15 A UNE EPAISSEUR PLUS GRANDE QUE LA PREMIERE COUCHE MAGNETIQUE 11.CETTE TETE MAGNETIQUE PERMET UN ENREGISTREMENT ET UNE LECTURE D'INFORMATIONS SOUS HAUTE DENSITE AVEC DE MEILLEURES CARACTERISTIQUES QUE LA TETE MAGNETIQUE CLASSIQUE. A thin film magnetic head for performing recording and readout operations to a magnetic recording medium and a method of manufacturing the head. The magnetic head [comprises] includes a substrate, a first magnetic layer formed on the substrate, a conductor coil on the first layer and a second magnetic layer formed on the conductor coil and the first magnetic layer. The second magnetic layer is imparted with a greater thickness than the first magnetic layer to thereby strengthen the magnetic field for recording and reducing the peak shift making appearance in readout operation due to interference between successively read-out waveforms. The thin film magnetic head exhibits an improved reproduction characteristic which permits reproduction with high fidelity the magnetized locations recorded on the medium with high recording density which assures an improved recording characteristic. By controlling the thickness of the second magnetic layer at an inclined portion thereof, magnetic saturation thereat is substantially prevented.
