Advantages of Z-CLV? (burning pattern method)


#1

Hello.

I am not saying, that Z•CLV (zoned constant linear velocity) is bad, but what are practical advantages of it? Doesn’t P-CAV already fullfill it’s purpose?
One advantage of zCLV is the beautiful circles on the disc writing surface, especially for DVD+R.

But what are some/the technical advantages of Z-CLV?
