Abstract
A control unit sets a first reading speed and a second reading speed of the information stored on the information medium as a function of a predetermined occupancy of the buffer below its storage capacity. The drive motor, which produces the reading speed, is connected via a switch to the driver which drives it and, during a reduction of the reading speed to a predetermined value or until the occupancy of the buffer falls below a predetermined occupancy, the power supply to the drive motor which produces the reading speed, is reduced by means of the switch for the purpose of reducing the power consumption.
