面が形成されている。FIG. 3 is a perspective view of a conventional magnetic recording/reproducing head of this type. In the figure, (1) is a core piece of soft magnetic material having a winding hole (2), and (3) is a core piece of soft magnetic material without a winding hole. The bonded surfaces of both core pieces (t) S (a) are fused with a glass material, and a tape sliding surface having a gap (4) for magnetic recording and reproduction is formed at one end of the bonded surface. ing.

A winding wire (7) is formed through the winding hole (2).
従来の磁気記録再生ヘッドは以上のように構成されてお
り、ギャップ（４）から巻線（７）の所まで離れている
ため、磁束の漏れが存在し、記録再生効率の向上に限界
があるという問題点があった。Conventional magnetic recording/reproducing heads are constructed as described above, and since the gap (4) and the winding (7) are far apart, there is leakage of magnetic flux, which limits the improvement of recording/reproducing efficiency. There was a problem.
この発明は上記の問題点を解消するためになされたもの
で、記録再生効率を向上し、高品質な記録再生ヘッドを
得ることを目的とする。This invention was made to solve the above problems, and aims to improve recording and reproducing efficiency and obtain a high quality recording and reproducing head.
この発明に係る磁気記録再生ヘッドは、ギャップを有す
る面に切り欠きを設け、その切り欠きと巻線用穴とを利
用して巻線を施したものである。The magnetic recording/reproducing head according to the present invention has a notch provided in a surface having a gap, and winding is performed using the notch and the winding hole.
この発明にあける磁気記録再生ヘッドは、ギャップと巻
線の距離が従来のものより近いため、記録再生効率が向
上し、高品質なものとなる。In the magnetic recording/reproducing head of the present invention, since the distance between the gap and the winding is shorter than that of the conventional head, the recording/reproducing efficiency is improved and the quality is high.
以下、この発明の一実施例を図について説明する。 An embodiment of the present invention will be described below with reference to the drawings.

。In Figure 1, (ri~(4), h and (7) indicate the same or equivalent parts as the conventional one, (8), (9)
is a notch provided on the tape sliding surface that comes into sliding contact with the tape (10). This notch (s), +9)
A winding (7) is applied through the winding hole (2) and the winding hole (2).
ただし、切や欠＃ （’ｙ） ＊ （ｓ）はテープ変形
に影響を与えない程度の大きさ、位置に設けている。However, the notch or notch # ('y) * (s) is provided in a size and position that does not affect tape deformation.
本発明の磁気記録再生ヘッドは以上のように構成されて
おり、巻線（７）の位置が従来のものよりギャップ（４
）に接近して形成されており、漏れ磁束を低減すること
ができる。The magnetic recording/reproducing head of the present invention is constructed as described above, and the position of the winding (7) is larger than that of the conventional one.

なお上記実施例では、巻線用穴（２）を片側のコア片（
１）にのみ設けているが、第２図に示すようにもう一方
のコア片（３）にも設けてもよい。In addition, in the above embodiment, the winding hole (2) is connected to one side of the core piece (
Although it is provided only on the core piece (1), it may also be provided on the other core piece (3) as shown in FIG.
以上のように、この発明によれば、ギャップ部付近に巻
