Dell Inspiron 1720 Owner's Manual page 58

Use blank CD-Rs to record music or permanently store data files. After
creating a CD-R, you cannot write to that CD-R again (see the Sonic
documentation for more information). Use a blank CD-RW if you plan to
erase, rewrite, or update information on that disc later.
Blank DVD+/-R or BD-R media can be used to permanently store large
amounts of information. After you create a DVD+/-R or BD-R, you may not
be able to write to that disc again if the disc is finalized or closed during the
final stage of the disc creation process. Use blank DVD+/-RW or BD-RE
media if you plan to erase, rewrite, or update information on that disc later.
