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:

Sony CRX175A has a very good writing quality with Ricoh's 74min 24x certified media. The average C1 error rate is 0.6 and the average burning time is 242secs. However, the PleXWriter is faster and also produced slightly higher quality CDs. Remember that PleXWriter PX-W2410A has been in the market from August and already 2 new firmware updates have been released. The following graphs come from the Ricoh 74min (24x-20x) media:

SONY CRX175A gave a high quality writing result, as you can see in the above graph. The produced C1 errors are below 5 cps for the largest recorded area, except from a small area (peak on the graph), which raise the average C1 result. Very good writing quality from SONY CRX175A!

Writing at 20x in the same type of media still gave very good results. The drive produced an average C1 error rate of 15 cps and kept the quality of writing in a high level throughout the whole 74min cd.

With Mitsui 74min 24x certified media, SONY CRX175A gave an 1.1 average C1 error rate which is the third best quality among the 24x Z-CLV tested recorders.

With Taiyo Yuden 74min 24x certified media the Sony CRX175A and LiteOn LTR-24102B produce the lower C1 error rate. Aopen CRW2440 comes second with 0.5 C1 error rate, Plextor and Yamaha come third with 0.6.

Sony CRX175A made the difference in the above table. It produced the lower C1 error rate (0.2) with the Mitsubishi Chemicals media, when all the other drives gave bigger rates.
