I don't understand why you have to approximate straight scanlines by using a fraction of a really large disk. What's the disadvantage in using a smaller disk and letting the scanlines be curved?

With the large disk, the difference between the (linear) velocities of different holes is smaller.

I would use a drum instead. You can make the scanlines near-perfectly linear if you look from a right angle.
