Writing Quality Tests
We used many media and burned them either with OWSC on/off with YAMAHA CRW-F1. We used Nero 5.5.9.2b for all the recordings. The produced CDs, were measured from DigitalDrives and results are illustrated in the following table

The general writing quality of YAMAHA CRW-F1 is more than adequate, in the maximum 44X recording speed. The error rate in most cases is low and no C2 errors occurred, with some exceptions with Plasmon, Emtec and SmartBuy (Prodisc) media, when the OWSC feature was not enabled. The importance of the OWSC system is clearly defined from the test results, where the quality was significantly increased when it was enabled. In cases were the inserted media did not support the 44X speed or a close to that speed, the OWSC lowered the writing speed to maintain better results, with a cost in the writing time, of course.
In the charts below there are some C1/C2 graphs showing the worst behaviors we had from the drive, when we used Plasmon, Emtec, SmartBuy and Taiyo Yuden media.
- Emtec 80min 24X @ 44X with OWC on
- Emtec 80min 24X @ 44X with OWC off
- Plasmon 80min 16X @ 44X with OWC on
- Plasmon 80min 16X @ 44X with OWC off
- SmartBuy 80min 32X @ 44X with OWC on
- SmartBuy 80min 32X @ 44X with OWC off
- Taiyo Yuden 80min 40X @ 44X with OWC on
- Taiyo Yuden 80min 40X @ 44X with OWC off
In the following table you can see the manufacturing details of the media we used for our tests.
