Ricoh 74min 24x Test Results - Ricoh MP9200A

We used the latest 20x and 24x recorders from various manufacturers in order to see how they perform with specific media brands under their maximum speeds. All CDs burned with Nero 5.5.3.5 and were Audio CDs with 74:51:27 lengh size.

- Test Results

In order to simplify the results we have gathered them in the following table:

The newer Ricoh MP9200A drive at 20x writing speed with JustSpeed enabled, produced an 1.2 C1 average error rate, which is certainly higher than the MP7200. Remember that the drive's firmware is only 1.00, when MP7200 is shipped with firmware version 1.30! MP7200 seems to be better calibrated, a natural consequence as the model has been in the market from May and records at a slight lower average speed as well, where the optomechanical system is less stressed. This drive's overall image is very good, but in the end, as in all cases tested thus far, the error rate is somewhat high.

The Ricoh MP9200, with JustSpeed disabled, produced higher C1 errors than when JustSpeed was enabled. This is what exactly Ricoh itself claims and it seems to be correct according to our evidence.
