Writing Quality Tests

We used Nero 5.5.8.2 as the CDR software. The produced CDs, were measured from DigitalDrives and results are illustrated in the following tables:

- 32x writing speed

The best quality results for PleXWriter PX-W4012U at 32x come with Plasmon 80min 24x media. Taiyo Yuden 80min 40x discs gave the best writing time but the C1 error rate is higher.

- 40x writing speed

At 40x, the Mitsui SG Ultra 80min 40x media gave a very low error rate. Very good results were also presented with Plextor (Hitachi-Maxell) 80min 40x media, which are bulked with the drive. The overall writing quality of the drive in the supported media is high. With un-supported media, the overall writing time is a higher (up to 10secs), and the writing quality is not as good as you might expected. Lastly, the drive doesn't seem to behave correctly with the new Mitsubishi Chemicals 48x media. Even it gave the best results, the produced quality is not as with other media.

- AudioCD writing quality

We measured the quality of some audio CDs recorded in the maximum 40x speed, at 24x, at 4x and again at 4x with the VariREC feature set to "0". The media we used for all the tests was Mitsubishi Chemicals 80min 48x. You can see the results in the table below.

The graph below comes from the CD we wrote at 40x, and the second one from the 4x recording with the VariREC feature enabled and set to "0"

Notice that the vertical axis is valued in logarithmic scale. The quality in the 4x recording speed is higher than in 40x, even if the difference is not easily recognized. However, the media we used is high quality and in a different case the role of the VariRec feature would be more efficient.
