。[Claims for Utility Model Registration] ■ In a VTR cylinder in which a rotating body with a magnetic head is rotatably supported on the central axis of a stationary body fixed on the chassis, the rotating body has an axial direction. A disk-shaped balance disk is fixed on a vertical plane with its center of gravity aligned with the center of the cylinder, and a weight attachment part is repeatedly attached to the disk at the same pitch around the center of gravity around the entire circumference. A VTR characterized in that balance weights are attached to these weight attachment portions at appropriate locations as necessary to balance the motion of the rotating body.
Cylinder. ■ The balance weight attachment part of the balance disc is made of a metal film that is pasted on a printed wire board with a circular surface exposed, and the balance weight is made of a metal film that is bonded to a printed circuit board with a circular surface exposed. A VTR cylinder according to claim 1 of the utility model registration claim. ■ The balance weight attachment part of the balance disc is a small hole formed in the balance disc, and the balance weight is made of a lead alloy that hardens at room temperature and is filled in the small hole. VTR cylinder described.
