Verification
To check for any errors on the recorded Traxdata 8x DVD+R media, K Probes Disc Quality Test was used to check for any high amounts of C1(PI) and C2(PIF) errors and failures with the LITEON 1633. To be a good recording no C2 failures should be seen and the lower the C1(PI) errors noted, the better the recording has been with the employed writer.
"It is common to see some C1(PI) and C2(PIF) errors and modern Writers are capable of correcting these easily, but there is a limit to how high the error can be before it is uncorrectable.
C2(PIF) failures stand little chance of being repaired and we will not pass any nedia has good that contains them in our Disc Quality tests and would recomend a slower recording speed for any media that shows these failures."
As the below screenshot of the recording at 8x on the NEC 3500AG from K Probes shows, the Traxdata 8x+R media had very low PI and PIF errors reported with a PI maximum of 18 and PIF max of just 2 with no failures being reported during the scan. The average PI error rate was just 6.32 and the average PIF error rate was a very pleasing 0.01 meaning this is an excellent recording at 8x to the Traxdata media with the NEC 3500AG. No drive should have any problems repairing and adjusting the errors whilst recording.
After seeing such good results at its rated recording speed, the next test was to use CD Speed's Create CD test again to see how well the Pioneer DVR 108 could record the to the Traxdata 8x+R media at an over speed of 12x. Bearing in mind this is a media being recorded at 50% past its rated recording speed, we can expect to see higher PI/PIF error levels, but a quality A grade media should be able to record past its rated speed and still show error levels well within the excepted error correction limits for DVD recordable capable drives.
As the screenhot from Kprobe shows, even after being recorded at 50% past its rated recording speed of 8x in the Pioneer DVR 108, hardly any difference in error levels can be noted. The Traxdata 8x+R media had very low PI and PIF errors reported with a PI maximum of 22 and PIF max of just 2 with no failures being reported during the scan. The average PI error rate was just 5.30 and the average PIF error rate was an amazing 0.01 meaning this is an excellent recording at 12x to the Traxdata media with the Pioneer DVR 108. No drive should have any problems repairing and adjusting the errors whilst recording.
With 12x recording at quality as this in the Pioneer DVR 108, we can see why Traxdata have decided not to release any 12x+R media and instead jump straight to 16x+R media production.
To check that no surface errors had been introduced into the media at the 12x overspeed, CD Speed's Scan utility was used to do a full scan of the media. Again no surface or file errors where noticed during the scan. truly we have a very good quality A grade media.
