Verbatim DVD+RW 4.7GB 25 pack - 43489 - 43489 DVD+RW Matt Silver. Verbatim's DVD-Rewritable (as well as CD-Rewritable) use a Super Eutectic Recording layer (SERL). SERL ensures that noise-free recording can be enjoyed time and time again. With conventional rewritable media, the recording layer deteriorates with every rewrite, meaning a decrease in quality. With Verbatim rewritable media however, the recording layer is returned to perfect condition on every erase cycle, leaving a flawless disc for the next recording. SERL also enables the media to enjoy excellent archival stability and high-speed recording. This means users can enjoy perfect, high-speed data storage every time. 1000 rewrites.
