Disk Drive


Named for the media disks that could be pulled out and that would ‘flop’ when carried. These disks are designed to allow users to store data to a disk, remove it and carry the data elsewhere. These typically come in one of two formats in the United States: 3.5″ @1.44Mbytes and 5.25″ at 1.22 Mbytes. There are a few proprietary types as well, such as Zip drives, DAT tapes etc.



Diskette stores data and information typed into the computer. These data and information are used when needed. Diskettes are also used to take information from one computer to theother.

There are two types of diskettes:


Floppy disk



The 3¹/² diskette is smaller than the 5¹/²diskette.Many more people like to use the 3 diskette than the 5 diskette. The 3 diskette also stores more information than the 5 diskette. When we need to know what is stored in the diskette, we put it in the disk drive. The disk drive is on the system unit.

Since the two types of diskettes are of different sizes, there are also different disk drives for each type of diskette. The 5¹/⁴ disk drive is for 5¹/⁴diskettes. It is at the upper part of the system unit. The 3¹/² disk drive is for 3¹/² diskettes. It is at the lower part of the system unit. The 3¹/² disk drive is smaller than the 5¹/⁴ disk drive.

In addition to the 5¹/⁴ and 3¹/² disk drives, there are also the CD ROM disk drive and the hard disk drives on the system unit. The CD ROM disk can be seen from outside while the hard disk drive is inside the system unit


1. Do not play with your diskette like a toy. This will damage the tape inside and this tape

2 Do not put your diskette near a hot object or surface.

3 Do not bend your diskette.

4 Keep all diskettes in a dry and safe place
