A reproducing system reproduces data recorded on an optical record carrier. The system includes a light source driver unit that modulates and controls a light output by a light source, such as a laser, in order to read data from an optical record carrier. The system is configured to operate in two modes: a reading mode and a light source lifetime extension mode. During the reading mode, the light source generates a continuous light output while data is read from the optical record carrier. During the light source lifetime extension mode, the light source generates a pulsed light output which may provide continued tracking and focus of the light on the optical record carrier, even when no data is being read from it.
