DVD+RW Alliance opens two new disc verification labs

The format verification laboratories test newly developed DVD+R, DVD+R DL and DVD+RW discs from media manufacturers to verify that read and write performance comply with the standard specifications. The verification report indicates improvement items to help manufacturers improve their production processes and product quality. The verification reports also advise manufacturers on the optimal writing strategy to be applied by DVD writers for this specific disc. Unlike other DVD formats, DVD+R and DVD+RW media include writing strategy information in the ADIP (address in pre-groove) information on the disc, thereby insuring that all DVD+R/+RW recorders and DVD+R/+RW writers use the best writing strategy for the specific media manufacturer's disc.

The goal of the media verification and certification program is to ensure optimal recording on discs in accordance with the standard. Only DVD+R or DVD+RW media that passes certification receives the certificate of conformance and is allowed to use the DVD+R, DVD+R DL or DVD+RW logo. Buying media with the +RW logo gives the consumer confidence that this media is tested and suited for reliable recording of all their precious data, photos and video materials.
