Abstract
A magnetic head 10 includes a pair of a C-type core 11 and an I-type core 12 which are butt-joined together, a gap section 14 defined between the butt-joined surfaces of the cores, track width regulating grooves 11b, 12b which are formed in a magnetic medium slide surface so as to limit the width of the gap 14 to a predetermined width, and bonding glass 16 bonded to the track width regulating grooves. The I-type core has track width regulating grooves which extend from the butt-joined surface to the outer side surface within at least the magnetic medium slide surface, and a reinforcing member 15 is attached to the outer side surface of the I-type core, so that the magnetic medium slide surface is extended.
