An integral combination magnetic transducer and suspension assembly suitable for use in both contact recording and in winchester-type applications is described. A generally rectangular elongated flat suspension member includes a vertical-type inductive read/write transducer formed integrally with the suspension member and is embedded in one end of the suspension member. The vertical inductive transducer is suitable for vertical recording applications. The transducer vertical magnetic pole tip and magnetic yoke structure are formed at one end of the suspension member with the vertical pole tip extending to and exposed at an air bearing surface formed on the lower surface of a slider-shaped protrusion extending from the lower surface of the end of the suspension member. The integral transducer/suspension assembly can be adapted for either flying above the recording media or for use in continuous contact with the recording media. The air bearing surface is formed on the lower surface of a wear pad. The fabrication of the transducer/suspension assembly is adapted to be performed at the wafer level.

La présente invention concerne un transducteur magnétique et une suspension combinés pour enregistrement en contact et applications de type Winchester. L'élément de suspension plat de forme essentiellement rectangulaire et allongée et le transducteur inductif vertical d'enregistrement-lecture de cette invention sont fabriqués d'un seul tenant, le transducteur étant encastré dans l'une des extrémités de l'élément de suspension. Le transducteur est conçu pour l'enregistrement vertical. Les pièces polaires et le collier magnétique du transducteur sont formés à l'une des extrémités de l'élément de suspension, de manière que les pièces polaires s'avancent dans un coussin d'air formé sur la face inférieure d'une saillie en forme de coulisse aménagée sur la face inférieure de l'élément de suspension. Le dispositif combiné de cette invention peut être conçu pour passer au-dessus du support d'enregistrement ou pour demeurer en contact avec le support d'enregistrement. Le coussin d'air est formé sur la surface inférieure d'une plaque d'usure. La fabrication du dispositif de cette invention se fait au niveau de la plaquette.
