Abstract
A MEMS-based rotational accelerometer has been recently developed by STMicroelectronics. This paper reports the preliminary results of its application to the reduction of vibration effects on a commercial Hard Disk Drive. Experimental results show that even with a simple feed-forward compensation, self-induced and external vibrations effects are greatly reduced up to 200 Hz.
