Title (EN) METHOD OF MACHINING SLIDER FOR MAGNETIC HEAD
(FR) PROCEDE D'USINAGE DE COULISSES POUR TETES MAGNETIQUES
Abstract:
(EN) A method of machining a slider (16) for a magnetic head used in a hard disk or a floppy disk in which a groove (11) and a recess can be formed in an arbitrary shape by using a masking material (14) and jetting fine abrasive grains carried by a carrier gas against the slider (16), and the edges of the surface of the slider (16) are rounded when necessary by blending-machining with the fine abrasive grains.
(FR) Procédé d'usinage d'une coulisse (16) pour une tête magnétique utilisée dans une unité de disque dur ou de disquette, dans laquelle on peut former une rainure (11) et un évidement de forme quelconque en utilisant un matériau de masque (14) et en projetant contre la coulisse (16) un abrasif finement granulé véhiculé par un gaz de transport. Les bords de la surface de la coulisse (16) sont arrondis lorsque cela est nécessaire par mélange-usinage à l'aide de l'abrasif finement granulé.
