  • Patent number: 6603719
    Abstract: A method for controlling the speed of a spindle motor of an optical information reproducing apparatus is provided. The method determines whether a data quantity of a buffer memory is sequentially larger than a first predetermined quantity during a period of read operation. If yes, the spindle motor is decelerated to a predetermined speed. The method also determines whether the data quantity of the buffer memory is sequentially less than a second predetermined quantity during a period of read operation. If so, the spindle motor is accelerated to a predetermined speed. The method according to the invention can automatically tune the speed of the spindle motor to a suitable speed to eliminate the noise that normally accompanies faster operation without lowering the information reproducing efficiency of the optical information reproducing apparatus.
