Correct so far!

Wrong. Surely recording doesn't spin up the disk any more than reading a
file during playback. The file size will be the same during recording it
as it will be during playing the same file back. Assuming the disk
spindown works the same during recording as it does during playback, then
it should be the same spinup/spindown times.

This is of course making the big assumption that recording is buffered
into a memory block the same size as playback is, and that writes occur
when the buffer fills over the same threshold as used when playing back

Without looking at the code, and watching a unit during recording I cannot
say whether these assumptions are reasonable though!
