DVD-R media compatibility and write quality

As with the +R media, for these tests we will be using either a Lite-On DVDRW LH-20A1H or the Lite-On DH20A3P  drives along with Nero’s CD-DVDspeed to measure the disc quality. We will also be using the BenQ DW1650 along with Nero CD-DVDSpeed for our read-back tests.

Here is what we discovered:

Disc Quality Scan at 4X with Lite-on Drive

TRT with BenQ DW-1650

The ASUS DRW-2014L1T did not do well with this media when burning at 20X as show with the high PIF in our quality scan.

TRT with BenQ DW-1650

The ASUS DRW-2014L1T burned this 16X with good results.

TRT with BenQ DW-1650

This media showed a dip in the TRT but scanned with acceptable results.

Smooth TRT and overall good quality for this media with the ASUS DRW-2014L1T

TRT with BenQ DW-1650

Good results with this Philips media.

The higher levels of PIE and PIF suggest problems with the quality on this media.

Despite the smooth TRT, the higher PIF at the end of the disc suggest that there might be questionable quality.

Our tests revealed that this media from Taiyo Yuden will permit writing at 20X with the ASUS DRW-2014L1T; we will show you the graphs and tables for both 16X and 20X writing:

Quality Scan at 4X for the high speed burn

TRT on our 20X write test

The quality scan shows this media with high PIF spikes at several positions on this media, this coupled with the TRT suggest that the DRW-2014L1T might have problems burning at 20X to this TY media.  Here again we see the speed drop just before reaching a full 20X.

Let’s see how the drive handles this TY media when writing at 16X:

As we can see there were still some spikes in PIF, however, they were lower and fewer in number.  The TRT reflects a smooth read back curve when burned at 16X.

The ASUS DRW-2014L1T performed very well with this media from Verbatim.

DVD-RW media compatibility and write quality

We used the same test procedures as in our DVD-R tests.

Here are our results.

The ASUS DRW-2014L1T did an excellent job with the RiDATA media.

The ASUS DRW-2014L1T did OK with this media from Verbatim.

Summary

Overall, the ASUS DRW-2014L1T did a good job with our DVD-R/RW test media; we would have like to have seen lower PIE/PIF values on our dash media.

Let’s head on to the next page where we will test DVD R DL writing performance and quality……
