Sound quality when recording in Storyline

When I record sound for a screencast using the 'Record Screen' option, the quality is great - no backrground noise. However, when I use the same equipment to record sound using the 'Record Mic' option, there's loads of background noise, and the quality isn't up to much. Why is this, and what can I do to improve the sound quality when recording using 'Record Mic'?
