Why does the ND-3500A do this ??

[Thornp]

I have just bought a new ND-3500A and started testing with my el-cheapo media (ie. A$0.25 ea) and was surprised to see that the burner seems to always dip in speed at every .5GB mark as illustrated below.



Manufacturer : TYG02
Code : -
Disc Type : DVD-R (Book Type: DVD-ROM)
Usage : General
Recording Layer : -
Recording Speed : 2 X - 12 X
Capacity : 4.38 GB
4707321856 Bytes
Additional Capacity : -
Overburn Capacity : -

Anyone know why it does this ?

The 3500AG adjust the burn quaility all thru the burn. What your seeing is the readjust of the burn. Second issue, TYG02 -R is one of the better DVD disc and should burn at 12X with no problem on the NEC.

That is a TYG02 code, not a Taiyo Yuden 8x DVD-R disc. BIG difference!

Very True - On average, they will burn fine at 4x but the ND-3500A throws a wobbly at 8x, forget 12x. As I said they are el-cheapo disks, very variable in quality, in fact some will not even be recognised by the drive, but speed is not that important. You mostly get what you pay for.

Where did you get these discs?

Where did you get these discs?

I bought a bulk lot of 600 from a reputable importer on e-bay for a total cost of approx. A$ 140.00, marked as SKY silver 'high quality' - probably chinese. I have decided I prefer the cleap Plus disks as they seem more reliable than the cheap minus ones. I mostly use them for Ghosting my machines, 2 or 3 times a week, and if Ghost is happy after verifying them, then so am I - and at that price I dont mind having to do it again if the disk is bad.
Video will work with almost any junk, data is a bit more picky.

Not even real TYG02 ( = plextor labeled ones for 2€ each) burn at 12x in that drive properly. PI sum 8 gets up to ~300
