The blank CD itself tells the burner software how much data can be put on it. And data is written and read from the inside out, so even without knowing the capacity, you'd simply write until you run out of space or data, whichever comes first.
Or maybe you're confused by the shape... the card-shaped CDs have a lot of wasted surface area, and only the circular area with a diameter equal to the widt of the smallest side is useful for data. The extra area making longer sides is unused.
