Abstract
A magnetic head device is disclosed, including a magnetic circuit having a head core unit, a back core and a coil. The head core unit includes a first core made from a magnetic material and a second core made from a magnetic material. A magnetic gap is formed between the first core and the second core. The back core is made from a magnetic material and is joined to the first core and the second core to form back gaps between the back core and vertical portions of the first and second cores, and the coil is mounted on the first core. The device includes a first holder which is bonded to the first and second cores at two locations, one on the side of the magnetic gap and one on the side of the back gaps, to hold the magnetic circuit. The device further includes a second holder which is bonded to the first and second cores at the magnetic gap side to hold the magnetic circuit, the second holder being substantially in the shape of a rectangular beam.
