CD-R/RW Writing performance

 

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.

DVR-112D, firmware 1.24 Replaced my first one for a second and this second one seems to have problems with audio extraction, some glitches which a generic DVD-reader doesn't produce... anyone else problems with this ?

Any digital out available on this drive ? I think it's not the case according to the main PCB picture. They do have a serial remote control instead but have not found any documentation yet. Jeremie

Got this one on my Mac drive. Does any one know where I can find the firmware to dezone it, (that is to turn it to RP-1 stage) ?
