Abstract | Tête magnétique à films minces et son procédé de fabrication. La tête magnétique comporte un patin-support 12 sur le bord de fuite duquel sont disposés directement les films minces 42 à 46 constituant l'élément de transduction de la tête. Après dépôt des films, la face active de l'élément de transduction ainsi qu'une partie du patin sont abrasées de façon à se trouver en retrait par rapport au reste de la face du patin. La partie abrasée est ensuite recouverte d'une couche de passivation 34 assurant la protection contre la corrosion par le milieu ambiant. Tête magnétique utilisable notamment dans les mémoires à disques.
A slider element includes a thin film transducer deposited onto a slider along at least one of the rails forming the flying air bearing surface with a magnetic media. A portion of the end tips of the pole pieces and gap of the thin film inductive transducer and a portion of the slider rail adjacent to the transducer is etched by a sputter etching process. A layer of a passivation material such as chromium is sputter deposited into the etched portion such that the leading portion of the rail protects the passivation material from wear. The passivation material over the pole tips of the transducer prevents the corrosion of the iron-nickel alloy comprising the pole tips. |
