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. |
| ■ |
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. |

Future Plans |
| |
We will increase the recording and reproduction speed by optimizing the stabilization board. |
