- Writing Tests

We burned a DVD+R DL and a DVD-R DL disc with data content. For this task we used "Create Data Disc" from Nero CDSpeed in order to fully burn the discs.

Mitsubishi Chemicals DVD+R DL 8X

The specific DL disc from Mitsubishi Chemicals is certified for 8X burning, one of the few if not the only one. According to the graph, the writing strategy is Z-CLV. The reported time of 19:13min is quite fast and is due to the fact that writing at 8X is done over the greater part of the disc's surface.

Mitsubishi Chemicals DVD-R DL 4X

This disc, according to the manufacturer, is certified for 4X recording, the speed that the Samsung SH-W162L drive burned it at. The writing strategy here is CLV.
