[QUOTE=zennchou;2101870]Recently, I bought a new Imation DVD-R 16x.
Then I compare with the older ones i have at home. The edges of the one are rough. The old ones od normal. Is it okay storing my precious data in the rough edge dvd-r?[/QUOTE]
Most likely they are from a different manufacturer.
Ritek and FTI seem to have more rough edges by using more glue to bond the layers together. In my experience these manufacturers having far less bonding problems as the others.
So rough edges caused by glue should be no problem.
I’m guessing your new batch of Imation is Ritek made.
