problem copying music to a disc

[bond]

hi, i am copying mp3 music files from my laptop to a disc, but they do not show on the disc when in insert it into another computer. i was told i could copy them, as opposed to actually writing them to the disc, since copying would take up less space, and i could then get hundreds onto a disc?? how do i achieve this, thanks?

They must be written to the disc - copying is writing to the disc. If you use Windows Explorer, you get the choice copying them as .mp3 files, or converting to audio. You get the same option with Nero, Roxio etc.
Assuming that you can see the files on the disc with your computer, it is possible the the disc could not be read in another computer because the disc wasn't 'finalised' and the second computer doesn't read discs which aren't finalised.
If you didn't finalise the disc, put it back in your computer, open Windows Explorer and right click on the drive letter. Select 'Close Session' and it will work.

It sounds to me like the files have been copied to the cd folder using explorer but haven't been burnt to the disk. Put the disk back into your computer and open it in my computer there should be an option to "Write these files to CD."
