Recording Information on a DVD
Your iMac has a SuperDrive, so you can record your own home movies on a blank
DVD+R DL, DVD±RW, or DVD±R disc. You can also record other kinds of digital data
(for example, you can back up your files).
To record data to a DVD disc using the Finder:
1 Insert a blank DVD+R DL, DVD±RW, or DVD±R disc in the drive.
2 In the dialog that appears, enter a name for the disc and select a format.
3 Double-click the DVD icon that appears on the desktop and drag files and folders to it.
4 Choose File > Burn Disc, or select the disc and drag it to the Burn Disc icon in the Dock.
You can also use iDVD to create your own customized DVD. For more information
about how to use iDVD, open iDVD and choose Help > iDVD Help.
