According to DigiTimes, Ritek is expecting the oversupply of DVD+R/-R discs to decrease or even disappear in the 4Q of this year. This decrease is partly due to the shift in production from 4.7GB single layer discs to 8.5GB dual layer discs.
The global supply of DVD+R/-R discs currently exceeds global demand, but the oversupply will begin to diminish next quarter and largely decrease or even disappear in the fourth quarter of this year, according to Ritek CEO Gordon Yeh, who spoke at a press conference following the company's 2006 shareholder meeting on June 14.

Although global DVD+R/-R demand is estimated to grow from four billion discs in 2005 to six billion discs this year, fast expansion of production around the world has resulted in the current oversupply, Yeh pointed out. But because leading makers of DVD+R/-R discs are shifting part of their production capacity for 4.7GB (single-sided single-layer) discs to making 8.5GB DL (single-sided double-layer) discs, the global oversupply is being reduced, Yeh indicated.
