OPTORITE DVD RW DD0405 - Page 11

HD BURN FUNCTION

HD-BURN allows writing twice the amount of data than can normally fit on a CD-R disc. This means that up to 1.4GB of data can be recorded on 700MB CD-R media. The Optorite DD0405 supports 24x writing speed for the HD-Burn option.

To check the performance of the Optorite DD0405 under HD-Burn we used NeroBurning Rom that supports the HD-Burn function. The available HD-Burn compilations are CD-ROM (ISO, UDF, ISO/UDF, Bootable), HD-BURN -Video or just copy an HD-BURN disc.

We used the HD-Burn ISO compilation of Nero to create a data disc that contains 1400mb. The writing process finished after 8:10 minutes and Nero informed us that the burn process was successful.

The HD-Burn written disc was fully readable with the Optorite drive. Unfortunately no other device was able to read the specific disc and that was expected since the HD-Burn function had the same performance on the previous versions of Optorite, the DD0203 and DD0401.

We used the Optorite for the reading test and NeroCDSpeed. The disc was read under CAV mode and the drive reached the maximum reading speed of 80.43x at the end of the test confirming the stated 78x speed, as per the manufacturer's specifications. Note that these speed marks look really high compared to those from 700MB data discs. This is because of the increased density of the recorded data under the HD-BURN mode.
