We developed a new type video disc player for baseband HDTV signal. In this system, HDTV signal is divided into 2 channels and recorded on the both sides of a 30cm diameter disc. This player reproduces them with two optical pickups at the same time. As a result, we can provide 30-minutes playing-time (CLV disc), even using conventional laser diode (λ=780nm).
