Sectors

A track can hold a fair amount of data. It would be a real waste of space to use an entire track for a small file. The track is broken into smaller parts called sectors. Going back to the thought of the racetrack. Think of the (human) track race called the relay race. A runner starts in his/her lane (like the track in a hard drive) and runs with the stick until they reach a point where they pass it off to the next runner. Each runner’s area could be thought of as the sector in a track.

Figure 56: A single sector.
