By implementing charged points on the magnetized layer, so a charged area (tens of nanometres a "dot") consists of being a 1 and uncharged area is 0, usually when "charged" the direction of the magnetized point changes, kind of like N and S on a magnet, the 1 is the dot's polar pointing N and 0 is when its pointing S.

What does a diskdrive use to store data?
There is a magnetic substrate on the surface of a platter, whether it's a hard drive or a floppy. A read/write head uses electrical impluses to rearrange the substrate into a series of ones and zeros, which are the only things a computer writes or understands.
What format do most computers store data in a series of ones and zeros?
binary
Can data be recovered from a zero-filled hard disk?
YES data can be recovered from a zerofilled hard drive but it is extremely difficult and costly process. To recover data from it one has to use a special equipment that has the ability to detect What new zeros have been put on the magnetic plates of hard drive. The process involoves detecting and separtating older magnetic field from the newer one. Let me explain it by an example: Consider a piece of data: 10110101 When you will zero fill the data will become 00000000 As the drive is formated all ones are converted to zeros. In this process new zeros replace the older ones but the older zeros remain "in place". This causes magnetic fields of slightly diffrent intensities on the surface of the disk i.e., the magnetic field of older zeros is of lesser intensity then that of the newer zeros. This change can be read by special equipment under special conditions . This is how FBI recovers data from a ZERO-FILLED hard drive. Hoping this will answer your question. Awais Rauf.
Where does hard disk information stored?
In magnetic particles on the hard drive disk surface. The drive head reads the magnetic particles and interprets if they are ones or zeros. The head doesn't touch the disk surface but resides about .00005 thousands away from the surface. Just opening the drive housing in an unclean environment can render the drive unusable. It also voids the warranty
Why do computers use zeros and ones?
They dont have to use zeros and ones. It can be anything that are oposite.
Is there more than one way to get binary code?
you can write the ones and zeros on paper as 1 or 0you can write the ones and zeros on paper as a row of triangles and squaresyou can paint the ones and zeros on canvas as a row of small dots and large dotsyou can show the ones and zeros by placing a row of 2x4 boards horizontally or verticallyyou can indicate the ones and zeros by using a row of red and green colored flagsyou can indicate the ones and zeros with a row of electric lights that are on or offyou can record the ones and zeros magnetically as flux reversals or no flux reversalsyou can record the ones and zeros magnetically as clockwise or counterclockwise magnetizationetc.
Does the CPU work with zeros and ones?
Yes, when it gets down to the basic data unit it's all about decoding and processing zeros and ones.
What is the function of a hard drive?
A hard disk is a device that is used to store large amounts of data in a computer system. Hard disks differ from other memory because they are non-volatile, they retain the data even when they do not have power.
What is it called when one Randomly writes magnetic ones and zeroes to a hard disk?
It is known as overwriting, in which a program is used to write zeroes and ones on the hard-drive. Several passes may be made to ensure the original data has been completely overwritten. Simply formatting a hard-drive is no good, as the data is still on the hard-drive, only the links to the data is removed, and the data can be recovered.
Which of the following storage devices can store the maximum amount of data?
Which of the following storage devices can store maximum amount of data ?. A Floopy Drive B Hard disk C Compact disk D Mangento optic disk
Can an external hard drive be used as a primary drive?
Only if you can boot from it. Most new computers can boot from a USB drive, but older ones may not be able to.
What is a random learner?
A person who learns random things for no reason. Or it can be a computer programed to shoot ones and zeros out of its shiney metal butt crack. Party Hard-Dumblefloor
