Abstract
A magnetic head device having excellent sliding contact between its slider surface and magnetic tape at the time of scanning is provided. This magnetic head device has a base member, a thin-film magnetic head formed in contact with the base member and accommodated in a non-magnetic layer with the top end of a magnetic gap being exposed, and an auxiliary member which sandwiches the non-magnetic layer between the auxiliary member and the base member. On the top ends of the base member, the non-magnetic layer, and the auxiliary member, a slider surface on which magnetic tape slides is formed in the aligning direction of the base member, the non-magnetic layer, and the auxiliary member, or in a direction inclined at a predetermined angle to the aligning direction. Accordingly, the non-magnetic layer can be made thin, and the area of the non-magnetic layer on the slider surface is small. Thus, the space between the magnetic head device and the magnetic tape can be made small, and the sliding contact of the magnetic head device can be improved.
