Dual mode auto-balancer for DVD drives |
摘要 |
A (DVD) drive unit for a variety of optical media including DVD discs or CD-ROM discs is capable of eliminating vibration while rotating and reading the optical media at either a constant linear velocity (CLV) or a constant angular velocity (CAV). In CAV mode, the drive unit uses ball bearings which are movable within a cavity in the turntable to counterbalance an unbalanced disc. In CLV mode, the drive unit utilizes a series of electromagnets to capture and symmetrically array the ball bearings within the cavity around the turntable.
