There are several different ways of storing information on the computer. One of the longest used systems for storing information have been with magnetic storage devices. Magnetic storage devices have improved in capacity and speed since they were first used. Smaller devices can now hold much more information. Even though other types of storage are becoming more popular, there are still many uses for magnetic storage devices.


Hard Drive

Inside the hard drive is a magnetic platter that stores all your information.

Most computer hard drives are magnetic, even today in 2010. The hard drive is where the computer's operating system and programs are stored. Without the hard drive, the computer would have to run off a disk that held not only the operating system, but any other programs that were needed. Running everything from a disk other than the hard drive will slow the entire system down.
