Minidisc recorder and noise floor

["cgorgen" <>]

I just got into recording of birds and picked up a Sony MZ-R37 off of
ebay. It was new so I went ahead and bought it. I recieved it this
week and have tested it out and it works fine. My first problem I
encountered was the noise floor when using the Audio-technica ATR-55
microphone. Is there something I can do to remove the noise post
processing or just get a better mike? I have other microphones and
they do not seem to create that much noise but they are also not as
sensitve as the ATR-55.
