CMCMAG AM3 16X Speed DVD-R
I have been fortunate to receive some pre production samples of the latest CMC 16X speed DVD-R media and being sceptical I decided to put them through their paces and I am so surprised at the quality of the results I cannot wait for the production to start before I publish my results
I understand from Datawrite that these will be marketed under the brand name Titanium 16X DVD-R and these results are comparable if not better than their 8x speed counterpart
The discs have the leadin mid code

I was only able to burn the DVD-R media iat 16X speed in 3 of my drives the other drives are limited to 8X speed with DVD-R media.
Here are my resultant test graphs
PIONEER DVR-108 V1.14 burnt at 16X speed
 |
A burn quality test in my BenQ drive
PI starting below 10 and peaking at a maximum of just over 20 with no sharp peaks, a good scan with this one
Jitter % starting well below 10% and remaining so for most of the scan with an average of 8.7 very good
PIF although low is a little disappointing peaking at a mere 13 and a minor cluster in the higher speed area
The time taken to complete this burn was 7m15sec |
 |
Speed test in the Toshiba drive
This scan shows an almost perfect graph again What more can I say? |
NEC ND-3500AG burnt at 16X speed  |
Burn quality as tested in the BenQ drive
PI again stating at about 10 rising to just over 20 at the end of the scan without any excessive peaks. This graph is very similar to the Pioneer scan but marginally higher A good scan
Jitter averages below 10% but does show an amount of fluctuation but still well within acceptable limits
PIF is also comparable with the Pioneer but marginally higher with a peak of 25 causing the rescaling up to40 max
The time taken to complete this burn was 6m40sec |
 |
Speed test in the Toshiba drive
Some minor blips in the read speed but the speed does not drop bellow 8 and there are only a few with minimal problems at the outer edge. I cannot see this causing any problems |
BENQ DW-1620 burnt at 16x Speed  |
Burn quality as tested in the BenQ drive
PI starting at just under 40 dropping down to 10 and then a slight rise to 20 at the end of the scan. This is the best graph I have obtained with recent CMCMAG media and this drive and although it is the highest of these three it is still a very good result
Jitter remains constant at just below 10% averaging below 10%
Although there are a lot of PIF errors the are all well below 10 and as such should not affect playback or readability
The time taken to complete this burn was 7m28sec |

Speed test in the Toshiba drive
As good as it gets

I only had a few of these pre production samples for trial but if the production is as good as these then this is another great disc to add to my collection. I cannot wait for Datawrite to start marketing them under the Titanium 16x brand. Which I understand will be towards the end of January
The burning times are actual times to complete the burn of a complete title set and is the total time taken for the burn including the leadin and lead out as recorded in the log of Record Now Max, The same title set was used for each of the burns and the time taken indicates that the maximum burning speed was only reached towards the end of the burn. A 4x speed burn takes about 15 minutes but you can see from these results that a 16X speed burn takes just halve as long and this is because the burning speed increases in stages from around 4x speed and only reaching 16X speed at the very last part of the burn process, it would be impossible to burn at the maximum speed at the commencement of the burn because of the high rotational speed that would be required and there would be a possibility of the disc shattering at such a high speed.
