Research and Advances on Shock and Vibration Resistance of Hard Dsik Drives

Hard disk drive(HDD) is the most important storage system in computers.Due to the importance and complexity of the problems of shock and vibration resistance in HDDs,many researchers have been investigating on these problems in various aspects.This paper begins with a brief introduction of the basic structure and the working principle of HDDs.The dynamic response characters and the failure mechanisms of HDDs subjected to shock and/or vibration are then summarized and analyzed.Finally,a systematic review of the state-of-the-art achievements on the shock and vibration robustness,as well as those of the controlling mechanisms,of HDDs are discussed.
