Abstract:
A magnetic head device for reading information from or writing information to a rotating magnetic recording medium, comprising:a magnetic pole for reading the information from or writing the information to the medium; and a slider for supporting said magnetic pole and for moving said magnetic pole on the medium, said slider including a contact portion for maintaining contact between the magnetic pole and the medium, the contact portion being joined directly to said magnetic pole, a flying portion for flying above the medium when the magnetic pole moves on the medium, the flying portion having a surface for facing the medium, the surface having a length in a rotating direction of the medium and a width in a direction perpendicular to the rotating direction of the medium and along the surface of the flying portion, the width being greater than the length, a connecting portion being coupled between the contact portion and flying portion, the connecting portion having a surface for facing the medium, the surface of the connecting portion being recessed from the surface of the flying portion, wherein a dynamic pressure generated by fluid-flow caused by rotation of the medium and acting on the slider is applied mainly to the surface of the flying portion.
