The bad news is that the floppy disc will only record MIDI information, which tells the device which note you hit and when, how hard you pressed that key down, etc, and then plays that information back to a device that can translate MIDI information.
The good news is that it has an aux out stereo channel which will send audio information out to a separate device like a hand-held recorder, cell phone, laptop, etc. I cant tell exactly from the manual but it would appear to be 1/4 stereo output jacks, and they are the holes in the middle of the seven jacks on the back. As you look at the back panel you will see the following from left to right:
(MIDI thru)(MIDI out)(MIDI in)(Aux Out Right)(Aux Out Left)(Aux In Right)(Aux Out L)
The three MIDI jacks on the left will be quite a bit larger than the four 1/4 jacks on the right. The cord you would need to go into a laptop from the Aux Out Left and Right would look like this:
