0. A CD does not record in a groove like a vinyl record.It is digital and records by making pits in the substrate at defined spacing which are read as 0 or 1 as digital code. The spaces correspond to 44.1 K per second which is the sample rate. A vinyl record only has one groove. Otherwise the stylus would have to jump from one to the next.

Grooves is not the truwe way to define the data storage area in a CD - refer to it as tracks. These aren't the number of music tracks on a CD however.
If you were to take a CD and unwind the tracks, there is over 50miles (80km) (I think this is it - it might be 500) of track data.
Quite surprising, but true! (I've MSc in the subject)
Hope this proves interesting reading!
