well, i guess you have the solution...
make a dir in your homefolder and copy (cp or man cp) all files from /mnt/cdrom/ to /home/newdir/
cp : copy files
cp file1 file2 : copies file1 to file2
cp file1 [file2...] dir : copies file to other directory
ATTENTION: This can change/overwrite existing files without warning!
use of wildcards : * ? and 
e.g. ls *.c : lists all files ending with `.c`
cp data* ~/backup : copies all files beginning with `data` to
rm *.c : removes all files with extension .c
`*` is a "shell metacharacter", the shell looks up all files that
match *.c, where * can stand for any number of characters of any
sort (alpa-numeric, special characters) and replaces *.c by the found
matching names, before ls is started.
e.g. ls /etc/?? : shows all files with a filename of 2 characters
in the /etc directory
'?' stands for one character of any sort
e.g. in a directory with the files 'oldfile', 'otherfile', 'ourfile'
ls o[lt]* : lists 'oldfile' and 'otherfile'
ls o[^lt]* : lists 'ourfile'
'' can be used to list alternative characters for a certain
position in a name and the ^ - sign can be used to specify that a
certain character should not appear on a certain position in a name
