いる。3 and 4 show the structure of the A / C head 9, and 10 is an audio erasing head, which is formed integrally with the A / C head 9. Here, the A / C head 9 includes core portions 9a, 9b (an example of a stereo head) of a voice head and a control core portion 9c, and the center portions 9a ', 9c of the respective core portions 9a, 9b, 9c.
Gaps (not shown) for recording and reproducing signals are formed in b'and 9c '. Further, the machining center Q of the radius R, which determines the outer vertex 9d of the A / C head 9, is the gap center 9
It is located on the same line as a ', 9b', 9c '.

分に得られないという問題があった。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the conventional A / C head 9 described above, the magnetic powder attached to the magnetic tape 2 is peeled off in the running path from the supply reel 5 to the A / C head 9. It is unavoidable that the magnetic powder is remarkably peeled off by sliding with the rotary head (not shown) embedded in the rotary drum 8. Further, as shown in FIG. 5, the separated magnetic powder 11 accumulates in the vicinity 12 of the A / C head 9 where the tape enters, and the positions of the gap centers 9a ', 9b' and 9c 'are the radius of the outer shell. Since it is located on the same line as the center Q of R, there is a problem that a space loss occurs between the magnetic tape 2 and the A / C head 9 at the position of the gap, and a desired reproduction output cannot be obtained. In addition, there is a problem that the input during recording cannot be sufficiently obtained.
本発明はこのような問題を解決するもので、スペース

るものである。The present invention solves such a problem, and an object thereof is to prevent the influence of space loss.
課題を解決するための手段 この問題を解決するために本発明は、信号を記録再生
するギャップ位置を外郭の頂点より走行する磁気テープ
の出射側の方向にずらしてなるものである。Means for Solving the Problem In order to solve this problem, the present invention is to shift the gap position for recording / reproducing signals in the direction of the emission side of the magnetic tape running from the apex of the outer contour.
作用 この構成により、磁気テープより剥離した磁性粉の滞
溜に起因するスペースロスによる影響がなくなり、記録

得ることができるようになる。Operation With this configuration, the influence of space loss due to the retention of the magnetic powder separated from the magnetic tape is eliminated, the input during recording can be sufficiently obtained, and the desired reproduction output can be obtained.
実施例 以下、本発明の一実施例について、図面（第１図，第
２図）に基づいて説明する。なお図中、前記従来例と同
一符号は同一部材を示す。Embodiment An embodiment of the present invention will be described below with reference to the drawings (FIGS. 1 and 2). In the figure, the same reference numerals as those in the conventional example indicate the same members.

ップを外郭の頂点9dの位置よりもテープ出射側の方向に
0.1〜0.2mmずらせた位置に設定している。In the figure, the center Q of the radius R of the outer contour of the A / C head 9 is positioned as usual, and the vertex 9d of the outer contour is also conventional. However, the gap between the centers 9a ′, 9b ′, 9c ′ of the core portions 9a, 9b, 9c is directed toward the tape output side with respect to the position of the apex 9d of the outer shell.
The position is shifted by 0.1 to 0.2 mm.
