High track density magnetic media with pitted optical servo tracks and method for stamping the tracks on the media. |
An intricate system of magnetic fields propelled the craft along and away from Earth. |
The two low magnetic field electric motors feature compensated stray fields and are each rated at 125kW for minehunting. |
By touching the white boards or by using magnetic pointers teachers and pupils can alter and rearrange the information displayed. |
It affixes to any outside surface of a car, and doesn't cause damage like magnetic signs or bumper stickers would. |
