Any idea what this graph means ?

[BlizzardUK]

All 16x Verbatim discs I burn on my USB2 LG drive come out like this...........

 

 

Where-as on my internal Pioneer BD-R drive the same Verbatim 16x comes out like this........

 

 

Burning at 8x on my Pioneer BD-R drive comes out like this...........

 

 

I have tried to use Opti Drive Control but am told neither of my drives support jitter tests.

 

My discs are Verbatim MCC03RG20 DVD-R

My external LG drive is : HL-DT-ST DVDRAM GE20NU11 CN01

My internal Pioneer drive is : PIONEER BD-RW BDR-206D 1.06

 

Here is a shot of a Ritek G05 at 8x on my LG external drive...........

 

 

 

So any idea whether the Verbatims are looking ok on there ? I used to use G05 all the time but just changed to Verbatim DVD-R today, so am hoping tests look ok. On the pics above the G05 one looks so clear and smooth, but is that irrelevant ? I can't imagine my drives coping with G05 better than Verbatims.

 

Thanks all !!

Looks to me as the LG has a problem to find a good write strategy above 12x and after some tries it decides to go for 12x on the rest of the burn.

 

For the Ritek burn, either your burner only supports those at max 8x or you selected 8x as write speed.

 

Pioneers are known to "jump" during the burn, so that graph looks like a normal one to me.Here is an example of a 16x write on one of my Pioneers.

Only a quality scan test can show which one that burned best. The posted images only shows how the disc was written. Not how good the burns were.
