摘要： A color display device has a single light guiding plate, and first, second and third light sources that respectively independently exhibit three primary colors. On a one end surface of the light guiding plate there are disposed the first and second light sources that exhibit two different ones of the three primary colors. On the other end surface side of the light guiding plate there is disposed the third light source that exhibits the remaining one primary color. Since the light guiding means is needed only one in number, the structure can be simplified and miniaturized. Also, on the one end surface of the light guiding means there are disposed, of the three light sources exhibiting the three primary colors, the first and second light sources that exhibit two different ones of the three primary colors. And, on the other end surface side of the light guiding means there is disposed the third light source that exhibits the remaining one primary color. Therefore, the probability that the light which enters into the light guiding means from one light source is hindered by another light source decreases. Accordingly, the loss of the light becomes lessened and the amount of light emission increases.

摘要： A system for recording information on an information recording disc such as a magnetic or optical disc. The recording system includes velocity control means for controlling the disc at a predetermined rotation velocity and synchronizing signal phase shifting means for shifting the phase of a synchronizing signal of a signal to be recorded. The system controls the rotation of the disc by the velocity control at the same velocity as the rotation velocity in the phase locked condition by the phase control in a very short period of time and during the recording of a signal the synchronizing signal of the signal is generated to conform with the rotational phase of the disc thereby producing the same condition as the phase locked condition.
