Writing Quality Tests

We used Ricoh's 74min 24x CD-R media. All CDs were burned at 24x writing speed for each drive with Nero 5.5.5.6 and 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-4809E gave better writing quality from the PleXWriter PX-W2410A, when Ricoh's 74min 24x certified media are used. The average C1 error rate is 0.5 and the average burning time is 242secs. The PleXWriter is 8 secs faster. Very good performance from Mitsumi CR-4809TE. The following graph comes from the Ricoh 74min (24x) media:

The Mitsumi CR-4809TE general writing quality was the best we have witnessed with Ricoh's 74min 24x certified media. The drive not only keeps C1 errors below 10 but also has very low C1 average error rate.

- More Writing Quality Results

With Mitsui 74min 24x certified media, the Mitsumi CR-4809TE has average writing quality with only 1.3 C1 average error rate. The burning time continues to stay at 242secs.

With Taiyo Yuden 74min 24x certified media, the Mitsumi CR-4809TE has very good performance with only 0.3 C1 error rate. The burning time is increased by 3 secs.

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-4809TE has the highest C1 error rate from the 24x Z-CLV recorders, while the average burning time stays at the same level as with the other media.
