I forget the brand name, but my computer has a CD burner which burns information on the BOTTOM of the disc--in whatever empty space remains outside of the main data space. It, too, produces questionably-decent images. However, you can use any discs in it. (Although certain brands/materials/coatings produce better results than others. The contrast level is exactly the same as the contrast between the data and non-data sections of your disc.) If you have discs which produce good contrast, it looks sharp--but you're limited to only using the outside space, so if your disc is full of data, you'll need a microscope to see the writing results. Not something great enough to go out of your way to get, but if you have a small project that you're going to be giving to someone, it can be a unique embellishment...
