Title
(EN) A PARTIALLY ETCHED PROTECTIVE OVERCOAT FOR A DISK DRIVE SLIDER
(FR) GARNITURE DE PROTECTION ATTAQUEE PARTIELLEMENT A L'ACIDE POUR PATIN D'UNITE DE DISQUES
Abstract
(EN)
For use in a disk drive, a head comprising a slider (26) having a bottom air bearing surface, a leading edge and a trailing edge; a magnetic transducer mounted by the slider at the trailing edge of the slider; and a protective overcoat (40) adhered to the air bearing surface of the slider and having a leading edge and a trailing edge. The trailing edge of the protective overcoat being spaced from the trailing edge of the slider such that the minimum distance from the slider to the surface of a disk in the disk drive is between the magnetic transducer (25) and the disk surface (22).
(FR)
Une tête d'une unité de disques comprend un patin (26) pourvu d'une surface inférieure à coussin d'air, un bord avant et un bord arrière; un transducteur magnétique tenu par le patin au niveau du bord arrière de celui-ci; et une garniture de protection (40) adhérant à la surface à coussin d'air du patin et comportant un bord avant et un bord arrière. Le bord arrière de la garniture de protection est espacé du bord avant du patin de sorte que la distance minimale entre le patin et la surface d'une unité de disques se trouve entre le transducteur magnétique (25) et la surface (22) du disque.
