録請求の範囲第１項に記載の磁気ヘツド。[Claims for Utility Model Registration] (1) Difference signal extraction for obtaining a difference signal between track division signals obtained by dividing and reproducing recorded signals recorded on the same recording track of a magnetic tape in the width direction of said recording track. It consists of a core around which a coil, the difference signal extraction coil and the reproducing coil are wound, and the core consists of two left and right core halves that are abutted against each other, and one core half is formed integrally. , the other core half has a divided core element divided in the width direction of the recording track and an auxiliary core element spanning between the divided core elements, and the difference signal extraction coil is wound around the auxiliary core element. A magnetic head characterized by: (2) The other core half consists of four divided core elements divided in the width direction of the recording track, and the auxiliary core element straddles the inner two divided core elements of the divided core elements. A magnetic head according to claim 1 of the utility model registration claim.
