を目的としたものである。In this conventional composite type magnetic head, in the work of winding the magnetic core f of the winding groove c, the winding contacts the upper and lower outer edge corners e of the winding groove,
The winding edge is apt to be caught by the edge of this corner portion, and defects such as disconnection and short circuit frequently occur, resulting in poor operation rate. Especially in recent years, there is a tendency for the total thickness to become thinner and the winding space to become smaller due to thinning, and strict restrictions are placed on the winding work in order to prevent short-circuiting between the magnetic core and the winding. There was also a problem with sex. The present invention is
In order to properly eliminate these conventional drawbacks, a composite type magnetic head that can greatly improve the winding work without causing defects such as disconnection or short circuit in the winding is simple and inexpensive for mass production type. It is intended to be provided in the form.

Since there is no winding, the winding can be safely and efficiently performed without being caught or damaged.

In the magnetic head, a chamfered portion 5 is formed at the outer edge corner of the winding groove 3 to form a floating magnetic head.

したものに適用できる。Further, the chamfered portion 5 is formed as a flat surface or a curved surface at an angle of about 45 ° both inside the groove corner so that the winding does not rub during winding work, and the groove width is gradually increased outward. Of course, the winding groove 3 is a groove having a straight bottom shape parallel to the side surface linearly extending from the side surface on the core piece side to the side surface on the opposite side, and as shown in FIG. It can be applied to a taper winding groove 3 1 having an inclined bottom surface ground to an inclined surface at an angle of, for example, about 30 °.

It is sometimes considered that the winding should be slippery and easy to escape.

頼性も著しく高めることができる。The present invention is a magnetic head having a concave winding groove and a magnetic core in a composite slider having two levitation rails, and a chamfered portion at the outer edge corner of the winding groove. By forming it, it is possible to perform safe winding work without damaging the winding or damaging the groove during winding work, contributing to quality improvement and without causing defects such as disconnection or short circuit in the winding work. The composite type magnetic head can be greatly improved, and the structure is simple and the mass-production type is inexpensive. Satisfying the thinness requirement, winding work restrictions are reduced, handling is easy, and reliability is significantly improved. You can
