A magnetic head core in which a pair of glass grooves extending between both half core blocks are formed at a predetermined interval on a sliding surface with a recording medium, and the track width is regulated by the interval between the pair of glass grooves. A magnetic head core characterized in that the inside of the winding groove is a space that is not filled with glass material for joining the half core, and the glass groove has a depth that does not communicate with the winding groove. (2) In paragraph 1 of the claims for utility model registration,
The minimum distance between the winding groove and the glass groove is 10-1
The magnetic head core is 5 μm.
