The uptrend has been attributed to increase in the number of makets and lowered prices of hardware and media. The US market is expected to account for 400,000 units of the projected demand, with around 450,000 units in Europe. The three current producers of CD-R equipment are Pioneer Corp, Marantz Japan and Royal Philips Electronics.
