Abstract
A magnetic head device for reading information from or writing information to a rotating magnetic recording medium includes a magnetic pole for reading information from or writing information to the medium and a slider for supporting the magnetic pole and moving the magnetic pole on the medium. The slider includes a contact portion for supporting the magnetic pole, and keeping the magnetic pole in contact with the medium, a positioned member flying above the medium, the flying member having a first surface where dynamic pressure generated by fluid-flow caused by rotation of the medium, and a connecting member having a mass less than that of the flying member, the connecting member connecting between the contact portion and the flying member.
