dbminter Posted December 6, 2013 Share Posted December 6, 2013 Why does the speed of a Verify on Layer 1 of DVD+R DL's gradually reduce from the highest point it reached at the end of the Layer 0 Verify? The Write speeds are relatively constant, meaning they go to X speed and generally stay at X speed, with only minor variations. But, the Verify of Layer 1 always gradually slows down. Just curious.

LIGHTNING UK! Posted December 6, 2013 Share Posted December 6, 2013 Because it reads from the middle to the outer edge and then the outer edge to the middle. Assuming the disc is always spinning at a constant speed, the transfer rate increases as you go from the middle of the disc to the outer edge of the disc - the opposite is therefore true when going from the outer edge to the middle.

dbminter Posted January 17, 2014 Author Share Posted January 17, 2014 Question about BD-R DL's and BD-RE DL's. Do they read the same way? With Layer 0 reading to a maximum X speed and then the reading of Layer 1 starting at that X maximum and then the speed gradually decreases? I've not had a chance yet to get any DL or XL media.
