CMC Magnetics（中环） and Ritek（铼德） will raise their quotations for DVD+R/-R discs by 3-5% each month this quarter, with the total price increase amounting to about 10% for the quarter, according to the two companies.

The price increases will vary based on the speed of the disc and the order volume, the two companies pointed out. In the case of 16x DVD+R/-R discs, the price level will rise from US$0.4 at the end of last month to US$0.44 at the end of this quarter.

As demand is expected to pick up this quarter, supply of DVD+R/-R discs may run short of demand up to 20% this quarter, CMC chairman Robert Wong（翁明显） and Ritek CEO Gordon Yeh（叶垂景） indicated.

Other Taiwan-based makers, including Prodisc Technology（精碟）, GigaStorage（国硕） and Lead Data（利碟）, are expected to follow suit and increase their DVD+R/-R disc prices.

这几家又嚷嚷着要涨价,不知道啥时候会拿出点实际行动来。估计是被股市逼的。
