Where's the track capacity formula?

I don't know where it is in the current books; I have it on an old reference card:

Space = C + K + D

C = 10

K, of course, depends on the key length.

  If KL = 0, K=0
  Otherwise:

  K = 9 + (KL + 6KN +6)/34

  Where: KN = (KL + 6)/232

D = 9 + (DL + 6DN + 6)/34

  Where: DN = (DL + 6)/232

Each result is rounded up to the nearest integer.
