<p>PURPOSE:To simplify a tape driving system and to improve the input/output characteristics of a magnetic head, by providing a limiter which controls the position of the magnetic tape width direction at one or both of the upper and lower ends in the width direction of a magnetic head main body so that the limiter has a light touch to the edge of a magnetic tape. CONSTITUTION:A limiter 8 which controls the tape width direction variation while a tape 3 of a record/reproduction magnetic head 5 is traveling toward an arrow (a) is set flat so that a projecting degree delta larger than the thickness of the tape 3 is secured at the upper part of the main body of the head 5 and that the limiter has a light touch to the edge of the tape 3. Otherwise pins 9 and 9 are provided at both upper sides of the head 5 in place of the limiter 8. It is also possible to set the limiter at the lower part or both upper and lower parts of the head 5. Thus a tape guide pin containing a limiter is not required, and therefore the tape vibration is eliminated. This can stabilize the input/output characteristics and at the same time simplify a tape driving system.</p> |
