The specifications of the Pioneer DVR-112D state that the drive is able to write CD-R discs at 40x and CD-RW at 32x. Let us find out how the drive really performs in speed and quality.

Writing Data CD-R discs:

Write quality:

We will test CD-R discs from many different CD-R manufacturers. To really measure the write speed, we used the “create data CD” function in Nero CD-Speed. The discs were written at the maximum speed that the drive supports. For the quality test, we used K-Probe 2 which is a tool developed by a Lite-On employee. It runs under Windows and works with drives made by Lite-On. Also note that different drives and different reading speeds may affect the results obtained when scanning the discs. We used a Lite-On SOHR-5238S drive with firmware 4S09 and scanned the discs at 48X speed.

A written CD-R disc will always have some C1 errors; C1 errors are easily corrected by the drive’s error correction capabilities. The next level of errors is C2, while C2 errors could also be corrected by most drive’s error correction capabilities; they are not wanted on a good quality disc. A good disc should not contain any C2 errors, and preferably have an average C1 error amount of below 2.0 for the best discs, or at least below 10.0 averages for good quality discs. After C2 errors, there are only un-correctable errors that will make a disc unusable.

Below are the obtained results:

An excellent result to start our CD-R quality tests, (highly recommended).

The write quality on the Verbatim 52x media is very good.

Our RICOH media manufactured by Moser Baer India has burned with very good quality.

Once again we have an excellent result, (highly recommended).

Another excellent result.

Writing Quality with Re-Writable discs:

The result is good.

Summary:

CD-R writing quality and media compatibility is very good with the Pioneer DVR-112D and CD-RW writing quality is good.
