Character and technique of recording:

This is a usual drive based on the Ricoh MP7200. It supports JustLink, JustSpeed and Zone-CLV technologies used for high-speed recording. The software allows starting to record CDs right after its installation.

Here is what the Nero says about this drive:

Earlier I mentioned that Ricoh clones and OEM versions do not like low-quality media. This time the AOpen recorder refused to record CD-R Mirex at the speed over 8X, though usually Mirex discs do not have any problems while being recorded at the speeds up to 24x.

Moreover, the drive doesn't get on with 24x CD-R discs from TDK Reflex Ultra. When we enabled the JustSpeed the CRW2040 refused to record at 20x coming down just to 16x.

The drive doesn't make much noise, though you can clearly hear air flows driven through it all the time. Discs ejected after intensive reading are quite warm. The spindown time is a bit too high.

The appearance of the drive is similar to the 16x model that we tested some time ago.

AOpen made the tray solid, without an opening door like in the Ricoh. In all other respects there's everything the same: a headphones jack, a mechanical volume control, an emergency ejection hole and one LED. The drive can be installed both in vertical and horizontal positions.

The rear panel features a special bridge for enabling the UltraDMA 33 mode; the PIO Mode 4 is set at default.

To make the drive work with this protocol you should just take out the bridge. We tested the device with the default settings, i.e. in the PIO Mode 4.
