various type of CD

Recording to CD - quick summary
There are two main types of media:
CD R - you can record to these, but only once
CD RW - you can record and erase these
DVD R and RW - similar, hold more data, but more formats and more opportunity for incompatibilities between media, drives and readers.
Blu-ray DVD - one of several emerging standards for high capacity DVDs (external link)
There's more than one type of cd drive, and they tend to look similar. Some can only read CDs, others can record to recordable CDs as well, these will hopefully have 'Recordable' or 'Rewritable' on the drive door.
Computers with drives that record are likely to have CD recording software on them too. Find that, and use it to record to your CD - at its simplest, this will involve starting the software, assembling a list of the files you want to put on the CD, and then having the software 'Burn' the CD in one operation. When a recording fails, the result is likely to be a trashed disk, so have a few spares available, especially the first time you use the software.
