Title (EN) METHOD FOR CORRECTING SURFACE SHAPE OF MAGNETIC HEAD SLIDER AND MAGNETIC HEAD SLIDER
(FR) PROCEDE DE CORRECTION DE LA FORME SUPERFICIELLE D'UN COULISSEAU DE TETE MAGNETIQUE, ET COULISSEAU DE TETE MAGNETIQUE
Abstract: front page image
(EN)A method for correcting the outer surface of a slider mainly made of ceramic to a desired surface shape, wherein a laser beam is applied to the outer face of a work (10) to partly melt the ceramic base, the melted part (20) is resolidified, and the surface shape of the slider is exactly corrected to a desired shape by using the shrinkage stress during the resolidification.
(FR)L'invention concerne un procédé permettant de corriger la surface extérieure d'un coulisseau essentiellement constitué de céramique, pour lui donner une forme superficielle désirée. A cet effet, on applique un faisceau laser sur la face extérieure d'une pièce (10) de manière à faire partiellement fondre la base en céramique; on laisse la partie fondue (20) se resolidifier; et l'on corrige avec précision la forme de la surface du coulisseau pour lui donner une forme désirée, en utilisant la contrainte due au retrait lors de la resolidification.
