A laser beam recorder for visual recording on 16mm color film from NTSC color television signals has been developed by NHK Technical Research Laboratories. In order to obtain precision laser beam scanning, a rotating mirror deflector employing a 25-sided polygonal mirror with a diameter of 60mm and a 3-phase synchronous motor with hydrodynamic air bearings rotating at 37,800 rpm has been specially manufactured. The results of recording experiments have shown that the quality of the picture recorded on fine grain, low sensitivity Eastman color print film 7381 or 7383 is excellent.
