If you have a sound-card, or external 'audio interface' that can process
signals from
more than one channel at once, then you can record either 'double mono'
or
stereo.
Which you get depends on the directional characteristics of the
microphones and
how they are positioned relative to each other. Stereo is not just two
sounds at
once, but (generally) two sounds captured at the same point in space.
Sound
recordists would usually use a pair of 'cardioid' response mics,
arranged in what's
called an 'X-Y' or 'crossed-pair' configuration. You can google these
terms.
