DVD-RAM 9.4GB OM940-400
     

OPTODISC Certified Plus DVD-RAM discs utilize a highly-refined phase-change recording alloy uniquely suited to the requirements of rewritable DVD. This allow provides a recording layer with a high reflectivity between 15% and 35%, along with the ability to register extremely small data points.

OPTODISC Certified Plus DVD-RAM discs are capable of thousands of read/write cycles, and offer an exceptionally high degree of stability and archival integrity. The discs are ideally suited to applications such as video and audio recording and multimedia development, where its ability to support repeated re-recording cycles can offer a significant advantage.
