Meantime Samsung Advanced Institute of Technology, the research and development arm of Samsung Electronics Co, says that it has developed Digital-Video Disk Recorder technology designed to record and play back more than 110 minutes of MPEG II video by using a green laser and magneto-optical recording. The wavelength of green laser light is half that of infra-red lasers currently used with 12 laser disks, enabling almost twice the number of spots and thus double the playing time. Samsung says it will incorporate the technology into a Digital-Video Disk Recorder it plans to launch in 1995. The technology was developed by Samsung under a $25m programme in partnership with Russian technology institutes, and includes a new compression algorithm.
