Method and apparatus for controlling motor rotation, and a disk signal regenerating apparatus using the motor

The present invention provides the following rotation control method for reducing energy consumption of a motor driving a disk. In a constant speed mode, a supply voltage V1 for driving the motor at a constant speed N1 is selected; however, at a lower constant speed N2, a supply voltage V2 lower tha...
