A magnetic head for carrying out recording or reproduction on or from a magnetic recording medium, comprises a shielding case having an opening in a sliding face for sliding contact with the magnetic recording medium, and a magnetic core having a projection provided with a magnetic gap portion, the magnetic gap portion being exposed through the opening of the shielding case. The projection of the magnetic core is formed to have an approximately trapezoidal, external shape incross section.

Magnetic head including magnetic core accommodated in shielding case

A magnetic head device includes a magnetic head for magnetically recording information on and/or reproducing information from a magnetic tape, a first pair of tape guides, each of which is formed as a single part and fixed to side surfaces on both sides of the magnetic head in a magnetic tape running direction, and a guide unit including (i) a second pair of tape guides which are independent of the first pair of tape guides and are arranged on the outside of the first pair of tape guides along the magnetic tape running direction and (ii) an opening portion to insert the magnetic head to which the first pair of tape guides is fixed in an almost center portion in the magnetic tape running direction. The guide unit and the second pair of tape guides are formed as one unit, and the magnetic head, in which an azimuth adjustment was performed in the opening portion and to which the first pair of tape guides is fixed, is fixed to the opening portion.
