<p>PROBLEM TO BE SOLVED: To provide a rotary magnetic head device which is capable of changing the lead height of a tape lead part of a fixed drum by a simple constitution and at a low cost. SOLUTION: The rotary magnetic head device is provided with the fixed drum 11, a rotary drum 14 which is rotably supported to the fixed drum via an axis 12 and a magnetic head 15 which is attached to the rotary drum 14 so as to be projected from the outer peripheral surface thereof. In the rotary magnetic head device 10, a magnetic tape is guided by bringing a side edge of the magnetic tape into contact with the tape lead part 18 which is provided as a step part at an outer peripheral surface of the fixed drum 11. The fixed drum 11 of this rotary magnetic head device 10 is constituted of a base part 21 which rotatably supports the rotary drum via a shaft and a drum part 22 of an another body which delineates an outer peripheral surface containing the tape lead part fixed and held to the base part 21.</p> |
