- Writing Tests

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

Mitsubishi Chemicals 8X DVD-R DL @ 8X Z-CLV

According to the graph, the writing strategy is Z-CLV. The reported time of 18:52min 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 4X DVD-R DL @ 4X CLV

This disc is certified for 4X recording, which is the speed at which the Samsung SH-S182D drive burned it. The writing strategy here is CLV.

Ricoh 8X DVD+R DL @ 8X Z-CLV
