Not strictly speaking.  Ogg is a framed power spectral density
format.  This is not much good when you try to play it through a
zero-order-hold DA converter (or almost any sort of DA converter, for
that matter).

Or, of course, if you want to record it so any old CD player can play
it (which I think was the original question) then you have to convert
it to PCM (or .wav, or raw, or whatever you want to call it) and stick
it on an audio CD.  If your audio CD holds ~72 minutes of audio then
you will need three CDs to hold it.

If you *don't* care about playing it on audio CD players (and my
impression was that the original poster does) then your method is
correct.
