During the first half of 2008, the price of blank DVD+R/-R DL media dropped by about 50% to around $1 a disc. These price drops have resulted in an increased demand, which both Ritek and CMC are reportedly benefiting from.
International retail prices of blank 4-6x DVD+R/-R DL discs have dropped by about 50% during the first half of 2008 to around US$1, spurring a fast growth in global demand. As the only two Taiwan-based makers of such discs, Ritek and CMC Magnetics are benefiting from the market surge, according to industry sources in Taiwan.

Japan-based Mitsubishi Kagaku Media (MKM) and Hitachi Maxell originally dominated the global production of such discs with relatively high OEM quotes, but Ritek, CMC and India-based Moser Baer India (MBI) entered the segment bringing price-cut competition, the sources indicated. As a result, OEM quotes have continually fallen and so have retail prices.
With blank Blu-ray Discs being relatively expensive, the demand for DVD+R/-R DL media is expected to double in 2009. If you'd like to read more, head on over to DigiTimes.
