PURPOSE:To obtain a magnetic head for magnetic disc storage device where damage for use is reduced, by providing smooth faces for floating at both edges to form a slider and by inserting and fixing a magnetic core into a groove provided at air flowing-out ends of smooth faces. CONSTITUTION:Groove 10 is provided at the air flowing-out end of one rail 9 of slider 7 having rails (smooth faces) 8 and 9 for generating floating force at both edges, and core 12 which forms a closed magnetic path through gap 11 is inserted into groove 10 and is fixed by glass melting, and after that, the floating face is processed and finished into a smooth face to obtain a magnetic head. Then, it is desirably that a material, which is nonmagnetic and has a mechanical strength sufficiently larger than ferrite, such as alumina and photoceramics is used as the material of slider 7. |
