Claims

[Scope of utility model registration request]

A pair of head halves 13 and 14 are joined by butting their magnetic gap forming surfaces, and the track width of the magnetic gap 10 is determined by the track width regulating groove 7 opened along the head halves joint.
, 7 and a sub-head 2 formed in the same manner as described above are arranged and joined in the tape transfer direction via the non-magnetic layer 3 to form an integrated magnetic head. The track width regulating grooves 7, 7 of the main head are formed across both main head halves 13, 14 with approximately the same width, while the track sub-regulating grooves 8.8 of the sub-head are The non-magnetic layer 3 is provided only on the head half 23 that is not in contact with the non-magnetic layer 3 without straddling the head halves 23 and 24 on both sides, or straddling the head halves on both sides. The straddle width X of the groove for the sub-head half 24 that is in contact with the head half 23 is the straddle width y for the other head half 23, and the straddle width y for the track width regulating groove of the main head for both the main head halves 13 and 14, respectively. A magnetic head characterized in that the magnetic head is smaller than y.
