Wobble and bow correction by dual spot pixel intensity proportioning

A raster scanning system comprising:

• a laser light source having a plurality of diodes for emitting a plurality of light beams;
• a medium;
• scanning means located in the path of said plurality of light beams from said laser light source for scanning said plurality of light beams onto said medium;
• said plurality of diodes being arranged in such a manner that there are a plurality of combinations of at least two diodes which are offset relative to each other and are arranged on a line which is at an angle to the direction of scan;
• the light beams from the diodes of each combination being spaced from each other along the direction of scan during simultaneous scanning of the light beams and arranged to scan partially overlapping paths to form a single scan line on said medium;
• controlling means for selecting one of said plurality of diodes or selecting one of said plurality of combinations of offset diodes;
• means for supplying a train of pixel information to said selected one of said plurality or to said selected combination of offset diodes;
• said train of pixel information supplying means being timed in such a manner that each one of the light beams from said selected combinations of offset diodes will be on at the same pixel location or will be off at the same pixel location along the scan line as the light beams move across the same scan line.
