Abstract
PURPOSE:To speed up switching in the decreasing direction of recording density by equipping a motor control means with a brake means for braking a motor when the rotating speed of the motor is higher than a set rotating speed. CONSTITUTION:A voltage comparator 308 compares voltage signals S307 and S308 with each other and outputs the result signal S310, which is inverted by an inverter 309 and outputted as a brake signal S303 to a distributor 303. When the level of the brake signal S303 is 'L', the distributor 303 turns off transistors TR1-3 and turn on transistors TR4-6 to apply a regeneration brake to the driving motor 34b. Therefore, when the actual rotating speed of the driving motor 34b is higher than the set rotating speed based upon a clock S12b, the brake signal S303 falls to 'L' and a brake circuit in the distributor 303 operates to apply the regeneration brake to the driving motor 34b. Consequently, the recording density is quickly switched in the decreasing direction.
