If your CD or DVD drive supports LightScribe, then you'll need this component to run it properly on your machine.
If you don't know what LightScribe is, it's basically a disk writer that allows you to create stunning CD and DVD covers directly in your CD/DVD drive. In this way, it doubles the capabilities of your DVD/CD drive. Creating a LightScribe disc is simple, but involves two separate processes according to the LightScribe developers. The data side is created using any traditional data authoring software, and if it's LightScribe enabled, the application may ask if you want to burn a label. It may help you in the cover creation process by actually downloading content appropriate to your CD or DVD that you are burning. However, if you are using a stand-alone disc labeling software, you will have to disable LightScribe and launch the software separately and design the label onscreen. In either case, simply remove the disk from your burner, turn it over and click "Print" to send the cover image to the drive. Hey Presto, you've got a ready made CD-DVD cover.
This is an essential component that you'll need to get the most out of your LightScribe drive - just check whether your drive supports it or not.
