Abstract
A pinch-holder for magnetic disc is provided in which a pinch member for holding a magnetic disc is brought into contact with the magnetic disc through at least two steps so that any damage on the magnetic disc can be prevented. Further, the magnetic heads provided as the pinch member is never subjected to strong impact force thereby preventing the magnetic heads from deteriorating or being damaged by such strong impact force and further reducing the noise generated by the solenoid used for driving the pinch member.
