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. In order to increase the recording density and decrease the time of positioning of magnetic heads, the tracks are positioned as close to each other as possible. However, the distance between them is not too close in order to avoid the creation of mutual noise.
