PROBLEM TO BE SOLVED: To set a track width precisely by eliminating occurrence of a pseudo magnetic gap inexpensively. SOLUTION: This magnetic head is a magnetic head 1 for recording and reproducing provided at a cylinder head of a 4 head Hi-Fi type and a 4 head type, has a pair of magnetic head core 5 being adjacent in a left and right symmetry type holding a gapαbetween them, a circular arc plane 10b connected to a magnetic recording medium sliding plane 5a is formed in a corner part 10 by processing the corner part 10 between a side plane 5b of a compact core half body 5b side of each magnetic head core 5 and the magnetic recording medium sliding plane 5a to a curved surface, a pair of track grooves 8 being parallel each other holding the prescribed track width (t) between them over the both side peripheries is provided at the both side peripheries of the magnetic recording medium sliding plane 5a, and a non-magnetic binder 9 is filled in each track groove 8.
