What is Magnetic Disk and there use | The working and features of Zip diskette was developed by Lomega Company, and it was an advance technology to tradition floppy disk, and it was used as a secondary storage device. Magnetic storage devices keep store the data with using magnetized medium, and those types of data saved in that medium in the binary form like as 0 and 1. As the head moves relative to the surface, the changes in magnetization from region to region are detected and recorded as zeros and ones. It is a hardware data storage medium that is used in the personal computers. A single detachable disk is employed as the media drive. Magnetic storage uses the two types of magnetic polarities to represent the binary information consisting of zeros and ones.

Electro-magnets are not naturally magnetic, but when you pass an electric current through them, they become magnetic. Core memories use hundreds of thousands of magnetizable ferrite cores that resemble tiny doughnuts. Tape backup systems are still in use today, but their importance has greatly declined with the advance of cheap, large capacity hard-disk drives. In the Magnetic storage devices, all data are stored with using magnetized medium, and those types of data saved in that medium in the binary form like as 0 and 1. A multiple fixed disc is employed as the media type. magnetic disk A rotatable storage medium usually in the form of a circular nonmagnetic rigid plate coated on both sides with magnetic material, followed by some form of lubricating layer (s). Different technologies vary in how the head moves relative to the surface of the media and how the regions on the media are organized, but the basic principle is the same.
