Abstract
In a portable electronic device having a data-storage drive that employs a rotatable data-storage carrier, as the data-storage carrier undergoes spin-up and spin-down cycles when the data-storage drive is being accessed, the electronic device recaptures at least a portion of the kinetic energy of the rotating data-storage carrier during the spin-downs to generate electrical currents and use them to either charge the battery or reduce the battery drain.
