Air-activated spindle/disk pack locking system

摘要

A disk drive has a brake mechanism located adjacent to its disk pack and actuator. The brake is pivotally mounted and movable into contact with the disks and actuator. Each end of brake has a bumper for cushioning the impact between the components and enhancing friction. A spring is used to bias the brake into contact with the disks. The brake is active or locked against the disks by the spring in the absence of air flow circulation from the rotation of the disks. The brake prevents disk from rotating and excessive movement or vibration. The brake deactivates or opens as a result of the air flow generated by the rotation of the disks. The air flow is sufficient to overcome the force generated by the spring.
