ブル。A disc suction type turntable in which a through hole is provided in the platter, and a disc placed on the platter is attracted to the platter by negative pressure from the through hole,
A soft magnetic material is attached to the back side of the platter via an elastic hollow member that is stretchable and whose hollow part communicates with the through hole, and an electromagnet is arranged to face the soft magnetic material without contacting it, A disk characterized in that by attracting the soft magnetic body by the electromagnetic attraction force of the electromagnet, the hollow elastic member is expanded and negative pressure is generated in the hollow portion and the through hole communicating therewith. Adsorption type turntable.
