The factors that affect disk storage capacity are: 1. Number of tracks; 2. Number of sectors; 3. Number of magnetic surfaces used. Disk is the main storage medium of computer. It can store a large amount of binary data and maintain data without loss even after power outage.

In order to read and write data on the specified area of the disk, each disk must be divided into numbers Equal concentric circles are called tracks, and each track is divided into several arc segments, called sectors. The capacity of a sector is 512 bytes. The capacity of a disk is the number of cylinders × the number of heads × the number of sectors × 512B.
