Abstract
An integral information and energy storage system is disclosed comprising a disk drive having a housing, a shaft rotatably mounted therein, and a disk platter coupled to the shaft. A flywheel is also coupled to the shaft and includes, embedded in the flywheel, magnets having magnetic fields emanating therefrom. Electrical coils are positioned in the housing for receiving electrical energy from a power supply line and generating an electromagnetic field effective for selectively repulsing or attracting the magnets to thereby rotate the flywheel and convert electrical energy in the coils into kinetic energy in the flywheel. Alternatively, if power is not available on the power supply line, the coils generate electrical energy as the magnetic field is caused from rotation of the flywheel and the magnet embedded therein to move across the coil, thereby converting kinetic energy in the flywheel back into electrical energy in the coil and to the power supply line.
