We developed a new type of optical disc system for baseband high definition television (signal. In conventional technology we cannot record HDTV signal for sufficiently long time because it has very wide bandwidth. In this system we can solve this problem based on the following technology HDTV signal is divided into two channels recorded on the both sides of a 30 cm diameter disc and reproduced with two optical pickups at the same time. As a result this system can continuously play HDTV signal for more than 30 minutes with constant-linear-velocity (CLV) disc. 1 .
