HDD Magnetic Track

As a result of recording the information by magnetic heads, magnetized areas in the shape of concentric circles occur on the surface of magnetic disks. They are called magnetic tracks. In other words, it is a set of sectors equidistant from the center of rotation of the magnetic disk. To increase the density of recording and reduce the time of positioning of magnetic heads tracks make as close as possible to each other. However, the distance between them is not too close to avoid the creation of mutual noise.
