ABSTRACT:
A rotary magnetic head device includes a stationary drum; a rotary drum having a rotary magnetic head; a rotor of a motor fixed to the rotary drum; a support shaft for pivotally supporting the rotary drum, the support shaft having a receiving face; a radial bearing for receiving a radial load, interposed between the rotary drum and the support shaft; a thrust bearing for receiving a thrust load, being slidably put on the receiving face; an urging member for urging the thrust bearing against the receiving face by pushing the rotary drum downward; and a reverse L-shaped support fixed to the stationary drum. The urging member is supported by the reverse L-shaped support and arranged on the rotary drum.
