ABSTRACT:
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.
