This IDC study presents data for and an analysis of the worldwide CD-ROM, DVD-ROM, CD-recordable/rewritable (CD-R/RW), combo, and DVD-recordable (DVD-Rec) markets. Data for 4Q06?4Q07 is based on actual sales figures; data for 4Q07?4Q08 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. The CD/DVD drive market showed moderate growth in 4Q07. The PC market's adoption of DVD burners is saturating, and the market is commoditizing.

"DVD burners will remain the bread-and-butter business for ODD vendors. Despite Blu-ray's win over HDD in the format war, BD drive adoption will be limited in 2008," said Wolfgang Schlichting, research director, Removable Storage, at IDC.
