Abstract
A data processing system including a data storage device having data stored on a data storage medium. Within said data processing system, a system electronics is operatively coupled to a sensor and to said data storage device. When the sensor senses a change in gravitational or inertial acceleration of said data processing system, it alerts system electronics to temporarily park a read/write head in a safe position.
