Un assemblage a transducteur magnetique (1) comprend une pluralite de noyaux magnetiques (2a-d) fixes a un curseur non-magnetique (4), le curseur ayant une pluralite de surfaces portantes de fluide (7a-d) supportant l'assemblage a transducteurs magnetiques sur une surface portante de fluide a proximite d'une surface de rotation telle qu'un disque magnetique. Chaque noyau magnetique possede une surface portante de fluide du curseur correspondante de largeur identique, les noyaux magnetiques etant fixes au bord de fuite (3) des surfaces portantes a fluide. Le curseur forme des surfaces portantes a fluide supplementaires (a-b) entre les surfaces portantes a fluide correspondantes. Magnetic transducer assembly (1) including a plurality of magnetic cores (2a-d) affixed to a nonmagnetic slider (4), the slider having a multiplicity of fluid bearing surfaces (7a-d) for supporting the magnetic transducer assembly on a fluid bearing proximate to a rotating surface such as a magnetic disc. Each magnetic core has a corresponding slider fluid bearing surface of equal width, the magnetic cores being affixed to the trailing edge (3) of the fluid bearing surfaces. The slider provides additional fluid bearing surfaces (8a-b) intermediate the corresponding fluid bearing surfaces.
