Japan’s Sony Corp said on Monday it would start sales next month of the world’s first DVD recorder that uses blue laser light and can pack a two-hour high-definition TV program onto a single disc. It won’t be cheap, with a retail list price of 450,000 yen ($3,800) while low-end DVD recorders using conventional red lasers go for as little as 50,000-70,000 yen.

But with digital satellite broadcasts in Japan, the United States and elsewhere now bringing high-definition TV to a small but growing number of households, Sony wants to get an early start in what could become a hot product.
