This product allows you to take notes (or jot down keywords) on specialist paper, while the pen simultaneously records the audio of what you’re writing about. So, you can touch a note you made last week and hear the corresponding audio played back.
Transfer your notes and audio to your computer via USB cable and the Livescribe Desktop will save everything for ready access to your audio recordings and written notes.

A digital voice recorder can also be helpful for study purposes. Again, follow the link for an example of this.
