<p>PURPOSE:To obtain a rotating magnetic head device capable of increasing the accuracy of mounting between outer rings and a rotating drum fixed to the outer rings or a fixing-side drum. CONSTITUTION:A rotating magnetic head device in which a rotating-side drum 2 is rotatably set to a fixed drum 4 is provided with a bearing 60 which is constituted of the rotating member 14 of the rotating-side drum 2 and a plurality of outer rings 15, 16 arranged in correspondence with the rotating member 14. The outer diameters of the outer rings 15, 16 of the bearing 60 all are set to be equal, and the fixing-side drum 4 is fixed to the outer rings 15, 16.</p> |
