Even if you are using a computer "so no one will be the wiser," always get your professor's permission before recording.
Keep in mind, in most states it is illegal to record an oral communication without the authorization of all parties involved. That's why you often get a message when calling a call center that "This conversation may be monitored for quality control purposes." For instance, check out Mass. General Law Chapter 272, Section 99 on the Massachusetts government website. I bet most states have similar laws.
There are a few exceptions to the law but they wouldn't cover a professor's lecture.
Not to mention it's not very efficient. If you spend 15 hours a week in class, are you going to spend another 15 hours a week listening to see what you missed? And how do you get it on paper or in your outline if you are driving, on a treadmill, or sleeping. Not to mention the risk of falling asleep at the wheel while listening.
You are better off taking good notes, even handwritten ones, on the rules, policy, terminology, and new hypos that the professor uses. That's not say you should transcripe every word said, just the important points and the areas you had trouble understanding in the reading. If you do this, I bet you won't wind up with more than 4-5 pages, and often less, per class. Then incorporate that into your outline later.
