DigiTimes has reported that CD-R disc prices have gone up 5-8% since the fourth quarter of 2006. According to their article, the price increase was partly due to Philips' Veeza licencing scheme.
OEM prices for blank CD-R discs have risen 5-8% since the fourth quarter of last year mainly due to Royal Philips Electronics' promotion of it Veeza licensing, but quotes for next quarter will not meet makers' expectations, with prices expected to remain flat, according to leading Taiwanese makers of optical discs.

With leading Taiwanese makers of CD-R discs accepting Veeza last quarter and early this year, large retail players in the US and Europe increased their inventory levels in anticipation of rising prices due to Veeza royalty payments, the sources indicated. The situation pushed up OEM prices of CD-R discs 5-8% this quarter and makers have been producing at full capacity, the sources noted.
