バランスバネ、１５は後方遠心カバランスバネである。FIG. 1 is an overall perspective view illustrating a rotating magnetic head drum to which the present invention is applied, FIG. 2 is a bottom view showing the rotating magnetic head portion taken along the line I--I in FIG. 1, and FIG. ■
4 to 6 are schematic diagrams for explaining the operation of the magnetic head section of the present invention, and FIG. 4 is a plan view showing a state in which the rotating drum is stopped, and FIG. Fig. 5 is a plan view similar to Fig. 4 showing a state in which the rotating drum is rotating in the pause mode, and Fig. 6 is a plan view similar to Fig. 4 showing a state in which the rotating drum is rotating in the recording or playback mode. A similar plan view, FIG. 7, is a chart showing the relationship between the number of rotations of the rotating drum and the amount of protrusion of the magnetic head. In the figure, 10 is a rotating magnetic head, 11 is a head chip, and 12 is a rotating magnetic head.
13 is a head substrate, 14 is a front centrifugal cover spring, and 15 is a rear centrifugal cover spring.

する磁気記録再生装置における回転磁気ヘッド。゛ A head substrate having a head chip fixed to the front end thereof is mounted on a support member fixed to the rotating drum through an elastic member so as to be swingable in the radial direction of the rotating drum, and the rotational speed of the rotating drum is controlled. By varying the amount, the head substrate is swung by the centrifugal force effect, and the amount of protrusion of the head chip from the circumferential side of the drum is varied. When in the pause mode, the rotating drum protrudes from the circumferential side of the drum so as to slide against the magnetic tape, and when in the pause mode, the rotating speed of the rotating drum is lowered and the drum is moved back close to the circumferential side of the drum, separating it from the magnetic tape. A rotating magnetic head in a magnetic recording/reproducing device.
