Acionador de discos para armazenamento de dados e aparelho de prevenção de danificação por choque

摘要

A technique for preventing damage to ball bearings in small form factor device is disclosed where the device has at least one crash stop ring disposed about the shaft and inside the rotor of a device. The ring is dimensioned to permit only a small amount of movement of the rotor relative to the shaft. The permitted movement is less than the minimum movement which would cause damage to the elements of the ball bearing.
