DVD Printing corrupts data

I have a Canon MP970 and have printed on a number of CDs without problem.

Recently I made copies of a data DVD then printed on the disks. When I
attempted to install the software from the copy, the installation failed,
early in the installation, stating that a file was corrupt. I have no idea
just how much of the data is corrupt.

I've tried this with three DVDs using the same software DVD and had the same
problem.

My next idea was to print the blank DVD then copy to it. That was
succesful.

Is it possible that the small metal DVD detector in the printer's disk tray
is causing the corruption?
 
I believe it is recommended, in general, that DVDs be printed to before
burning data to them. I suspect that the printing process may damage
the data in some manner, although I honestly don;t know what damage can
be accomplished during the printing process, since DVDs have their light
sensitive layer in the middle of the DVD disk, laminated with
polycarbonate to either sides of it. Perhaps you are correct that
something in the printer can damage the DVD dyes which could corrupt
the data integrity. Interesting...

Unlike writable (and even manufactured) CDs where both the data and
reflective layer are just under the top surface, both the light
sensitive and reflective layers are in the middle of the disk,
sandwiched between the two layers of polycarbonate plastic, so they are
well protected.

This is why I was somewhat suspect of the printer damaging the data (and
reflective) layers. I should have probably been clearer in my posting
in that the recommendation by the printers manufacturers to print before
burning is probably much more significant with CDs than DVDs.

Interesting. I wasn't aware of any recommendation to print before burning,
but it's certainly going to be my method from now on.

Now was I. the only problems I had heard of were from labels, the gum
of which does damage the discs.
 
Your Epson manual is correct. Mea Culpa.

I apologize for this error. I did indeed mix up the sequence, and I
thank you for correcting my error. The last thing I want to do is
disseminate incorrect information.

I'll strike it up to sleep deprivation, but no excuses, it was the wrong
info and I'm glad you were able to correct it.

Then using my experience with DVDs and a Canon MP970, I'd suggest you keep
that order a secret and don't spread the word.

The advice I would give for this combination is print first then burn.
 
Sounds to me like it either is random and is the luck of the draw, or it
differs depending on the printer, the DVDs the burning and the ?stage of
the moon?

I wonder if one needs to stand on one leg also...

Maybe so, but I definitely had 2 different brands of DVD.
 
I know I am responding to my own posting...

I have been giving more thought to the matter of the sequencing of
burning versus printing CDs and DVDs, and wondering why different people
are reporting opposite results.

I think that first of all a distinction may be required between CDs and
DVDs. As I mentioned previously, DVDs have polycarbonate protecting
both sides of the writable data layer, while CDs have a very thin
lacquer coating between the writable layer, the reflective layer and the
top "printable" surface.

CDs are vulnerable to the data layer being damaged when printing the top
layer, due to physical damage or the dye possibly entering the
reflective layer. This can't really happen with a DVD. However, DVDs
can be written at a very high speed and perhaps the possibility of
placing the disk off balance with the inks could be enough to make it
write incorrectly, or be stressful to the burner motors.

This is conjecture, but it may have some logic.
