PURPOSE:To realize the reduction of a product cost and the thinning of a product simultaneously by integrating a rotary disk and a rotary drum, and mounting a rotary magnet unit directly on the rotary drum supported rotatably freely by a fixed main shaft setting the projecting part of the rotary drum as a bearing part. CONSTITUTION:The rotary disk 7 is integrated with the rotary drum 14, and also, the rotary magnet unit 9 is mounted directly on the rotary drum 14 supported rotatably freely by the fixed main shaft 13 setting the projecting part 15 of the rotary drum 14 as the bearing part. Therefore, it is possible to simplify the assembling process of a rotary head mechanism. Also, the rotary magnet unit 9 is mounted adjacently to the rotary drum, and a terminal 7 from the rotating side 6 of a cylindrical rotary transformer arranged on the inner diameter side of the rotary magnet unit 9 is connected to a magnetic head 5 via a notch 16 provided at a part of the projecting part 15 of the rotary drum. In such a way, it is possible to realize the reduction of the product cost and the thinning of the product. |
