The usual practice is to take good notes and then send an email or letter summarizing the points covered and confirming the action plan with a request for correction. Recording could imply a lack of trust and make your participants worry about how they sound rather than focusing on the meeting.
I suppose if you explained it in some benign way, like you have difficulty taking notes and asking questions but you want to make notes later, that might help. Everyone will be more relaxed and natural without a recording though.
