Nero CD-DVD Speed: Basic CD Tests

I used five CD media to perform these tests: a molded CD-ROM enclosed with a computer magazine, 700MB data CD-R and CD-RW discs recorded by Nero CD-DVD Speed itself, a likewise prepared 800MB CD-R, and an Audio CD.

You may note the strange behavior of the Pioneer DVR-110D with the 800MB CD-R – there are three stretches with a constant rotational speed on the diagram, and the speeds on these stretches decline towards the outermost tracks of the disc.
