There are two possible things you might mean by "Groove" to people in the brake industry.
1) A slot that is ground down into the pad usually in the center is used to prevent cracking, reduce tangential stiffness, reduce fade, and clean corrosion off the rotor.
2) A scoring mark going tangentially on the surface of the pad, generally means that at some point in time previously a small piece of iron disloged itself from the rotor and compacted onto the pad surface. It was then dragged accross the pad surface until it ejected from betweent he pad and the rotor. In this case you'll generally also notice a similar wear path on the rotor.
