Today, we will see how well a SmartBuy DVD+R DL disc burn in the Optiarc AD-7561A drive.
This unit supports burning these discs at a speed of 2.4x and 4x. This post will focus on a disc burned at 4x.
Burning the disc seem to have gone well:
While in the very first image I realized it doesn’t show the burning speed, it was actually burning at 2.4x. Same as the last image, since the drive burns in 2 zones, using the Z-CLV strategy. The rest of the discs burned at a constant 3.8x speed.
The disc verification was successful:
This is how the disc surface looks after burning:
You can see there are 2 visible zones in the disc, which are the 2.4x and 4x zones.
We will now see some disc quality scans from the above disc. All of the scans are performed at a speed of 4x, except in the Optiarc AD-7561A and AD-7740H drives, and in the Pioneer BDR-2212 drive.
LiteOn iHAS524 A
This is a very good scan with only a few elevated numbers in the 2nd layer.
LiteOn iHBS112 2
This drive always seem to scan the PIF correctly but reports a lot of error in the PIE.
Numbers similar to the LiteOn iHAS524 drive, except the PIE are a bit higher by a few numbers.
This drive always reports elevated numbers.
Elevated PIE numbers here, but the PIF numbers appears to be fine.
Another good result.
Unfortunately, this drive is not suitable to scan DVD+R DL media, but the disc itself is readable. This drive always fails in the layer break when scanning this type of disc.
As we can see, the Optiarc AD-7561A is a great drive to burn these discs. It will do it without any issues and will verify correctly. The disc also scanned with good results in all drives when we take into account the PIF numbers. All of the drives reports different numbers for the PIE, especially in the 2nd layer. However, we can conclude that this is a good burn taking into account the PIF numbers alone.
