English: This shows the technology of the SuperDisk drive. Two voice coil servomotors move the drive heads precisely across the disk surface. Highlighted in blue is the main servo with a large coil providing the primary force to move the head mechanism. In yellow is a secondary smaller coil that primarily acts to keep the head mechanism aligned parallel with the disk surface. To the back in red is the drive eject motor, which allows the disk to be under computer control so that it normally will not eject until the computer has completed its read or writing tasks.
