Methods for encoding transitions between low-intensity regions and high-intensity regions such that the transitions are more readily detectable in a digital image captured by a digital image capture device. Therefore, the force is introduced perpendicular via the center sleeve sliders, and absorbed via the supporting plate or moving identification plate. This method virtually eliminates the artifacts associated with the earlier reset-release timing method without the bit-ordering restriction of the jog-clear method. The display unit includes a user interface providing a first area for displaying data of the first disk device and a second area for displaying data of the second disk device. Therefore, the voltage from the third connecting terminal of the first switch is stabilized and is outputted as the output voltage of the controllable power supply device by the linear regulator. The unaliased and deblurred image is calculated for each coil, and the final image is formed from the images for all of the coils.
