A computer rigid is same as of different magnetic disks, used for a data-storage purpose. A hard disk is made up of several computers rigid disks. Floppy, compact discs, zip discs and, etc., are all examples of computer rigid disks. With the passage of time, the computer rigid disk has been revolutionized and has become an important part of computer development.

They are used for storage purposes, and today it is also used as the secondary or extended memory storage device. In order to make it available for the storage of huge amounts of data, several rigid disks can be used. The data on these disks is recorded through a magnetic material. Its surface is composed of many small magnetic domains in a perpendicular form. Each of these magnetic domains consists of very small magnetic grains.

These computer rigid disks are used in both desktops and laptops. Their performance is measured in RPM (revolutions per minute). The higher the RPM, the faster will be the disk. RPM actually determines that how rapidly a data can be stored on the disk. Its capacity can be measured like other magnetic disks. They are reliable, easy to use and portable, which makes it easy to carry the data.

One of the best features that computer rigid disks possessed is their capability of recovery. In olden days when magnetic disks got damaged due to any reason, it was impossible to recover data from it. However, the new rigid disks allow the full recovery of the data. If your disk suffers any loss of data, take it to the professional technical person, and he can easily recover the data. There are a number of companies making excellent and reliable computer rigid disks to satisfy the need of computer geeks. They are now readily available in the market in different storage limits.
