    • A head drum assembly for a tape recorder includes a stationary drum, a rotary drum, a magnetic head installed in the rotary drum for scanning a traveling magnetic tape, and at least one vibration absorbing unit installed in the stationary drum for absorbing vibrations associated with the traveling magnetic tape. The head drum assembly absorbs vibrations via a vibration absorbing element elastically biased to protrude toward the outer circumferential surface of the stationary drum by a spring installed in an opening of a portion of the stationary drum such that the vibration absorbing element makes contact with the magnetic tape. As the vibration absorbing element makes contact with the traveling magnetic tape, it gives appropriate tension to the magnetic tape to dampen any vibration created therefrom.
    • 用于磁带录音机的磁头鼓组件包括固定磁鼓,旋转磁鼓,安装在用于扫描行进磁带的旋转磁鼓中的磁头,以及至少一个安装在固定磁鼓中的吸振单元,用于吸收与 旅行磁带。 磁头鼓组件通过安装在固定磁鼓的一部分的开口中的弹簧弹性偏压以朝向固定磁鼓的外圆周表面突出的振动吸收元件吸收振动,使得振动吸收元件与磁带接触 。 随着振动吸收元件与行进磁带接触,它给磁带提供适当的张力,以抑制从其产生的振动。
