This IDC study presents data for and an analysis of the worldwide CD-ROM, DVD-ROM, CD-R/RW, combo, and DVD-Rec markets. Data for 3Q05?3Q06 is based on actual sales figures; data for 3Q06?3Q07 is forecast. Storage formats are grouped into five categories: CD-ROM, DVD-ROM, CD-RW, combo, and DVD-Rec.

Detailed data for each category is given in terms of market value and unit shipments. Market share is given for ROM versus recordable drives. Additionally, unit shipments are analyzed and forecast by slim versus half-height (HH) form factor.

CD/DVD drive market growth showed a surprising weakness in the third quarter of 2006. The PC market has been aggressively adopting DVD burners. However, opportunities also continue to exist for older technologies in the commercial PC market.

"CD/DVD drive vendors must get ready for stiff price competition in 2006 and 2007 because the DVD feature race is coming to an end and mainstream blue laser?based products are still more than a year away," said Wolfgang Schlichting, research director, Removable Storage, at IDC.
