Question re copying cassette tapes

[Rudy Troike]

Howdy, all,

    I'm planning to copy some old language tapes on cassettes to a CD format.
Any caveats would be welcome. One question -- for this purpose, is it 
necessary
to use "music CDs", or will ordinary CD-R disks work?

    Thanks,

    Rudy
