Abstract

A magnetic head device according to the present invention comprises a head core formed of a magnetic material. The head core includes a sliding portion having a magnetic gap defined therein and adapted to be in sliding contact with a magnetic record medium, and a pair of leg portions formed integrally with the sliding portion. A coil is wound around one of the leg portions of the head core. The head core is held between a pair of holder shells, which each have one end coupled to the sliding portion of the head core and the other end extending toward the other ends of the two leg portions of the head core to be coupled thereto. At least one of the holder shells is formed integrally with a connecting portion which, formed of a magnetic material, constitutes part of the other end of the holder shell, so that the connecting portion and the head core define a closed magnetic path passing through the magnetic gap.
