Abstract

PURPOSE:To reduce an adsorption phenomenon by reducing the area of contact with a disk medium by swelling the rail surfaces of the rails of a core slider, and providing a magnetic transducer at the end part in an air inflow direction. CONSTITUTION:At the center part of the block 2d of the core slider 2 of a head 1 floated by an air flow, a rail 2e is provided in an air inflow direction A; and its rail surface 2f is swelled out with prescribed curvature, and a magnetic transducer 5 made of a thin-film pattern is buried in the rear end part. Slider rails 2a and 2a' are bonded to both ends of the block 2d, and their rail surfaces 2b and 2b are formed in the same shape with the rail surface 2f. Thus, the area of contact between the head 1 and a medium surface 3a is reduced greatly, and its adsorptive force is reduced extremely to prevent an accident, such as a head crush, during restarting.
