This IDC study presents data for and analysis of the worldwide CD-ROM, DVD-ROM, CD-R/RW, combo, and DVD-Rec markets. Data for 4Q04-4Q05 is based on actual sales figures; data for 1Q06-4Q06 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 factors.

The CD/DVD drive market continued to show strong growth in 2005. The home 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, 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.
