Structural Design of Hard Drives

Hard disk drives are well known as secondary storage devices, with the capacity to store massive amount of data on your system. Almost every computer whether desktop or portable must possess one or more hard disks to capture data on long term basis. Hard disk drives are non-volatile storage device made up of circular plastic and magnetic material and can accumulate digitally programmed figures in an eternal form.

Today’s modern hard drives have extensively replaced the older magnetic tapes, videocassette recorder and other audio/video capturing devices. Every Hard disk possesses two different read and write heads for reading and writing the content into it.

Every common hard disk has two electric motors to rotate and locate the read/write heads. Hard disk motor comprises of an external glide connected to the platters in the hard disk. There is an eternal magnetic shuffling coil glide that move backward and forward the heads to the preferred places to store data on to it.
