Verbatim's DVD-Rewriteable (as well as its CD-Rewriteable) use a Super Eutectic Recording Layer (SERL). SERL ensures that noise-free recording can be enjoyed time and time again. With conventional rewriteable media, the recording layer deteriorates with every rewrite, meaning a decrease in quality. With Verbatim rewriteable media however, the recording layer is returned to perfect condition on every erase cycle, leaving a flawless disk for the next recording. SERL also enables this media to enjoy excellent archival stability and high-speed recording. This means users can enjoy perfect, high-speed data storage every time.
