With the aim of developing a recording media for next-generation archiving of Hi-Vision images, we have been conducting research on a thin optical disk that is thin and soft and can rotate and record at high speed. The disk has the low error rate required for high-speed recording of Hi-Vision images at 250 Mbps.
line
250-Mbps recording
  A high-speed recording capability equivalent to that of a Hi-Vision VTR for broadcasting (250 Mbps) was achieved by improving the rotation characteristics of the disk and the algorithm for controlling the optical beam’s location.
line
Low error rate
  The low error rate required for high-speed recording of Hi-Vision images was achieved by making the recording media flatter and more sensitive.
line
Future Plans
  We will increase the recording and reproduction speed by optimizing the stabilization board.
