Abstract
The present invention provides a protection device and method of a read and write medium apparatus. When the read and write medium apparatus is operating, the protection device detects the external force and dynamically compels to cut the power supply off to remain the apparatus in non-operating condition. Besides, after the external force is withdrawn, the protection device can make the apparatus return to its prior operation operating condition. Thus, the invention enhances the shock-proof, drop-proof and collision-proof capabilities of the read and write medium apparatus and the protection thereof further.
