An optical disc drive 1 includes a spindle motor 11 for rotating the optical disc 2 and a spindle driver for driving the spindle motor 11 equipped with a rotation number counter 232 for measuring the rotation number of the spindle motor 11. A brake for braking the spindle motor 11 to reduce the rotation number thereof, can include at least three types of brake modes, and a selector for selecting one of the types of brake modes in response to the rotation number measured by the rotation number counter 232 when the rotation number of the spindle motor 11 is to be reduced. The optical disc drive 1 may further include a judging circuit for judging whether the rotation number of spindle motor 11 measured by the rotation number counter 232 reaches a predetermined target rotation number when the rotation of the optical disc 2 is to be stopped by the spindle motor 11. In this case, the application of the brake is completed when the rotation number of the spindle motor 11 reaches the predetermined target rotation number.
