To prepare a digital storage medium (like a floppy disk) so that it will accept and store digital information bits.

Analog Recording
A recording of the continuous changes of an audio waveform.

Balanced input/output
A "balanced" connection is one that has three wires to move the signal. One is a ground, and the other two (called conductors) carry signals of equal value. This is why they are called balanced. Low Z cables and connections are the most common example.
