Abstract
PURPOSE:To realize a high-density recording by setting the minimum record radius of the video disk to nr (n: integer of >=2; r: recordable minimum radius) and then the rotational frequency of the disk to 1/n respectively. CONSTITUTION:The rotational velocity VR given to the disk driving system 11 from outside is set to 1/2 compared with the velocity decided by the scale of the disk main body. And furthermore if both the record optical system 12 and the reproduction optical system 13 are excluded out of the subject of scanning in the range from r to 2r, the record of two screens becomes possible with every track and in the region from the radius 2r to the radius 2R (R: recordable maximum radius).
