Recording device with laser scanning on light sensitive carrier

摘要

The recording device reflects a laser light of a laser light source, for sampling of a photosensitive record carrier on a polygon mirror. The device includes a section for detecting the intensity of the laser light reflected at each surface area of the polygon mirror, to measure the reflection amount. A device is provided for an individual storing of the intensity signals. A mechanism is provided to read an intensity signal stored for a reflection surface area, if the next scanning with the laser light results through this reflection surface area. A device corrects a reference voltage in response to the read intensity signal, and a first output control adjusts the emission of the laser light of light source, dependent on the corrected reference voltage.
