Write Quality

Now we are going to test CD-R discs from different CD-R manufacturers.  To measure the write speed we will use the “create data CD” function from within Nero CD-DVD Speed.  We wrote these discs at the maximum speed that the drive supports.  For the quality test, we used KProbe 2 which is a tool developed by a Lite-On employee.  KProbe runs under Windows and works with the 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 CD-RW SOHR-5239V with firmware 2$0B 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 quality 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.

So, in short, our analysis will be based on these guidelines to determine the quality of the burned discs:

Below you will see our obtained results:

Verbatim DataLifePlus CD-R burned good with average C1 errors of 0.37 and without C2 errors.  This media goes into the “Best” quality discs category.

This Verbatim media – manufactured by CMC Magnetics Corp. burned with a C1 error average of 0.39 and without C2 errors which will place it in the “Best” disc quality category.

Media manufactured by Taiyo Yuden have always enjoyed a good reputation and with this burn resulting in C1 errors of 0.07, without C2 errors places it in the “Best” quality category.  This media is highly recommended.

The Sony media burned with C1 error average of 0.56 and no C2 errors which will put this media into the “Best” quality category.

The LG GSA-H62LI also produced C2 errors averaging 0.10 which will put it in the “Poor” quality category in spite of a low C1 average of 0.24.

Writing Quality with Re-Writable discs

High C1 error average of 54.64 and the presence of C2 errors place this media in the “Poor” quality category.

Summary

The LG GSA-H62LI is a fast CD-R writer but is showing questionable results with C2 errors on one of our CD-R test media as well as our CD-RW media.
