The storage system inside a PC, be it a diskette, a tape storage or a hard disk, consists of three logical parts. First part is the medium itself, that is the diskette, the cartridge tape or the hard disk. The second part is the mechanism that operates this medium—spins the disk or spools the tape. This is called the drive. The various kinds of drive are the floppy disk drive, the tape drive and the hard disk drive. The third part is the electronics, that controls the drive through commands given by the computer system. This is called the controller. In this section, you will learn about the floppy disk and hard disk systems.
