Using Dual-Axis Accelerometers to Protect Hard Disk Drives

The increasing use of hard disk drives in portable equipment has fueled the need to prevent their destruction when a product that contains one is accidentally dropped. This article describes a novel technique that calculates differential acceleration, thus allowing a dual-axis accelerometer to sense an impending collision in time to park the read/write head and protect the head and the platter from damage.
