Magnetic head device having sloped sliding surface which is formed thermally curved

摘要

A magnetic disk recording/reproducing head device includes a slider member, a magnetic circuit, and a seal member. The slider member is made of a magnetic material. The slider member has at least one sliding surface opposing a recording/reproducing disk, both end portions thereof being formed in a direction perpendicular to the sliding surface. The slider member has a groove portion which is formed in one of the end portions to be parallel to the sliding surface. The magnetic circuit in the present invention has a core member made of a magnetic material and fixed to the other of the end portions of the sliding member, a predetermined magnetic gap which is formed between the core member and the slider member, and a coil which is wound around the core member. The seal member is made of a material having an adhesive property upon melting and a shrinking property upon stiffening and is sealed in the groove portion of the slider member so as to form an inwardly recessed tapered portion on part of the sliding surface corresponding to the groove portion when the seal member stiffens.
