Title (EN) METHOD OF MANUFACTURING A MAGNETIC RECORDING HEAD AND MASK USED THEREFOR
(FR) METHODE DE FABRICATION D'UNE TETE D'ENREGISTREMENT MAGNETIQUE ET MASQUE UTILISE POUR CE FAIRE
Abstract:
(EN) A method and device are provided for inexpensively and easily masking a magnetic recording head to be ion-beam milled. According to the invention, a magnetic mask (36) comprising a magnet shaped to form a mask (36) for a predefined pattern, is used in place of more expensive and complex photolithographic techniques to mask, or protect, a predefined area of the magnetic recording head being milled from the ion-beam.
(FR) Méthode et dispositif pour masquer facilement et avec un faible coût une tête d'enregistrement magnétique devant être traitée avec un faisceau d'ions. Selon cette invention, un masque magnétique (36) comprenant un aimant de taille à former un masque (36) pour un modèle prédéfini, est utilisé à la place de techniques photolithographiques complexes et coûteuses pour masquer, ou protéger, une zone prédéfinie de la tête d'enregistrement magnétique traitée par le faisceau d'ions.
