High Capacity DVD tech Question

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
I was referred to the expertise of this group by those at

I am presently utilizing Fire Wire drives to store and/or deliver high
resolution satellite imagery on.  These images usually include four or five
individual files that are each 8 or 9 gig in size.  All of these files need
to be in the same directory for a GIS to load the image. However, these
individual files can be delivered or stored as individual files. As such, a
standard 4.7 gig DVD is too small, yet even an 80 gig Fire Wire Drive is
often overkill.

I would therefore like to know if the higher capacity 8+ gig DVDs might
provide a better solution.  I realize I would need to up-grade to the
appropriate burner/drive (recommendations?), but will my clients be able to
read these higher capacity DVDs on their standard DVD ROMs without a
problem?   Excuse my ignorance, but the reason I ask is that I can presently
insert a movie-on-dvd into my standard DVD-ROM and it plays just fine...yet
the movie is 7.5 gigs and evidently burned on a high capacity DVD.

Any advise would be appreciated. Thank you

I find that is an issue in any case when it comes to optical
media. No matter what media you use, there will always be
customers phoning to complain they cannot read your stuff.

Have a look at the "PC Data Storage" section here. Rather futuristic
but not far around the corner.

Yes- a standard DVD player will play a dual layer disk.
There are a number of good dual layer recorders. I use a Plextor 916A
(overpriced, but good quality).  The one I see recommended a lot is the
Just as with commercial DVD movies, there is a slight (less than one second)
pause at the layer break when viewing the DVD. If that would affect your
task, then you would want to have the layer transition occur between
individual files. I'm don't have the knowledge to tell you how to do that,
or if it's even a factor.

Good Luck,
