How is information stored on the hard drive of your computer?

Answer 1

Writing to Hard Disk Drive (HDD)

At the most basic level when a computer writes anything to any media, even going back to the old "floppy" disks, it is in bits and bytes which are simply positive and negative images electronically recorded on the physical media. Some are one time only like a CD, others can be rewritten, some information can only be accessed sequentially, others must have an index.

Hard dirves are made up of bits and bytes, sectors,files, indexes and they all inter-relate to store the information.

The disk drive head writes a magnetic pattern onto the spinning metallic disk similar (but at a much greater speed & density), to the way the old floppy disks worked. A modern disk drive has several individual disks contained in one drive, on the same spindle, and multiple heads between the disks to achieve todays mega and gigabyte capacities, and speed. The head does NOT contact the media, but actually flies above the disk, analogous to a jet flying over a runway at full speed without ever landing. A "touch and go landing" of the drive's head would permanently damage the disk.

Answer 2

Information is stored on a computer's hard drive with the use of binary, or the system in which data is stored through an intricate series of 0's and 1's. These 0's and 1's are very much like on and off switches, triggering either a stop or flow of electrical energy.

Answer 3

Something to do with the magnetic coating, look that up and you'll get a better idea. I;m doing the same thing, trying to figure that out.

data in hard disk is stored in binary form(0's & 1's).hard disk is made up of ferromagnetic material(it can be magnetized and demagnetized).

the read/write head present in hard disk magnetizes the platter.thus data is stored in it.deletion is done by demagnetizing the particular sector and track.
