Writing Quality Tests

We used many medias ,mostly 24x certified, and burned them at the maximum 32x (Z-CLV) writing speed with the Mitsumi CR-480ATE drive. We used Nero 5.5.5.7 and all CDs were Audio CDs with 74:51:27 in size. The produced CDs, were measured from DigitalDrives and results are illustrated in the following tables:

The Mitsumi CR-480AE didn't perform so well with Mitsui's 24x CD-R media. The drive needs 5:15mins to end the task. The drive lowered the recording speed down to 16x for writing Mitsui's 74min 24x media. The average 0.8 C1 error rate is very good:

With Taiyo Yuden 74min 24x certified media, the Mitsumi CR-480ATE performed very well and not only has the lower recording time but also very low C1 error rate (0.1).

None of the tested drives seem to give a very good writing quality when Mitsubishi Chemicals (Verbatim) 74min 24x certified media used. The Mitsumi CR-480ATE however managed not only to have the lower C1 error rate, but also the lower recording time (due to 32x writing speed).

Using various other media we noticed that in the cases of Ritek and Mitsui the drive lowered the recording speed down to 16x (32x was selected in the first place). Using Maxell based CDR media, the error rate is very high (25.6 average C1 errors),which can be explained since the media was probably prototype. However the Taiyo Yuden/Ricoh 80min 24x certified media seems working just fine.
