Howdy, Framily.
What is the difference between a CD for a DVD and a plain vanilla CD? Longer, lower, wider?  :D

I have a midi file on a 3.5 floppy that has to be read with an external 3.4 drive. No problem.  I want to "put" this file on a CD. Do I use a DVD CD?

Thanks,
Liz

The CD and DVD are identical to LOOK at ... same size, etc.
The metal layer inside them is different though, and the way a computer encodes data on them is different.  What it amounts to, though, is a CD will hold about 700MB of data.... a DVD will hold more than 4 GB of data (that's more than 6 CD's on a single DVD).  (And your Floppy holds about 1.4 MB of data... not much by comparison.)
So if your file fits on a Floppy, then it'll fit on a CD.... CD's sell for about 30 cents apiece in bulk, DVD's are about a dollar apiece.

If you want to be able to play this MIDI file in a CD player (like a car or home stereo) you will need to make sure it is re-formatted to an AIFF file and then "burned" as a music CD (not on a DVD)... there are several programs that will do this ... iTunes will (it's free, and most people seem to have it.)

OK. Thank you.
