"Is there any way to tell just by looking as a disk?"

Not every time...depending on the manufacturer, but there ARE things you
can look for.

The re-recordables DVD-RW and DVD+RW, will have small "barcode" looking
stripes in the middle, near the hub. SOMETIMES, a DVD-R or DVD+R will be
labeled as such, near the hub, but this isn't consistent between
manufacturers. One possible indicator of whether it is a recordable, is
you can see the recorded area. On a stamped DVD, sometimes you cannot
see where the recording stops. The issue there, is that if you recorded
the whole disk, there wouldn't be a "line" where the recording stops.
When SOME manufacturers stamp their DVDs, they add an aesthetic layer,
so you can't see where the data stops. In general, look at the hub area
and see if it is labeled DVD-R or DVD+R.
