Many users find that floppy disks are too unreliable to transport their work regularly, and that they don't hold enough data. A CD will hold around 500 times as much information as a floppy disk, but the processes for writing data to them is different. Both CD-R and CD-RW media are available at any computer accessories store.
Types of CD
There are two common types of CD:
* CD-R (Recordable) - You can keep adding data to this type of CD until it is full. Once full, there is no way to delete files that you no-longer need. The advantage is that they are more compatible with other CD drives and the media is slightly cheaper.
* CD-RW (Rewritable) - With rewritable CDs you can add and remove files. However, you may find that you can't read the CD in some older computers. For the best compatibility, you should ensure that any media you use is rated with the lower level of "4x" (e.g. 2x - 10x is OK, 8x - 24x is less compatible).
Storing Your Data Using Roxio CD Creator
Most of the labs PCs across the University, as well as newer staff PCs, are equiped with CD writers and Roxio CD Creator software.
To write a CD, you should first copy your files to a local storage area - for example if your files are on your H: drive or on a floppy disk, you may want to copy them to the desktop.
A. Insert the CD media you want to write to into the CD drive
B. Go to Start -> Programs -> Roxio CD Creator to start the CD writing software. The intial screen will look like this:
C. Move the mouse over the "Make a data CD" button (highlighted above) and you will see the following screen:
D. Click "Data CD Project" and wait a few moments while the writing application starts. Once the application is ready, you will see a screen similar to the one below:
The numbers on the image above are:
1. The files on your local hard disk. You can navigate directories just as you
would in Windows' file manager.
2. The files waiting to the be copied. You drag files and directories that
you want on your CD from the local hard disk to this area. If you are
using a CD-RW you will see the contents already on the CD here - you
can also select files and click "Remove" to delete files from the CD
(you must still click "Record" to actually remove the files).
3. Once all your files are ready,click "Record" to burn to files to the disc.
4. The turquiose bar shows the amount of space you will be using on the
disc. Once the bar is full, you cannot write any more data to the CD.
E. Once you click "Record" another dialog box will appear. Click "Start Recording" to being writing the CD. Depending on the size of data you are writing to the CD, recording may take some time - a bar will show the progress of the recording.
F. When your recording is complete, the program will ask you whether you want to save the project (i.e. to allow you to create another identical CD later). Usually you will just click "No" here.
