What material is commonly used for hard disk platters?
Hard disk platters are commonly made of a magnetic material called cobalt alloy or aluminum alloy.
What are hard drive platters made of and how do they contribute to the functionality of a hard drive?
Hard drive platters are typically made of glass or aluminum coated with a magnetic material. These platters store data by using a read/write head to magnetically encode and retrieve information. The platters' smooth surface and precise spinning motion are crucial for the read/write head to accurately access and store data, making them essential for the functionality of a hard drive.
What material is ebonite made from?
ebonite is made by reacting 100% cotton with sulphuric acid
What is the difference between metal and medal?
Metal refers to a type of material that is typically hard, shiny, malleable, and a good conductor of heat and electricity, such as iron, copper, or gold. A medal, on the other hand, is a piece of metal that is often awarded as a symbol of achievement or recognition, typically in the form of a decorative pendant or disk.
What is BeN2?
BeN2 is beryllium nitride, a chemical compound made of beryllium and nitrogen atoms. It is a hard, high-melting-point material with potential applications in electronic and optoelectronic devices.

Can a CD be affected by a magnet?
No, unlike the platters of a hard disk drive, Compact Discs (CDs) are made from polycarbonate and recorded on by lasers, and thus are not susceptible to damage by magnets.
Should I recycle hard drive platters?
Yes, you should recycle hard drive platters. Hard drive platters are made of aluminum, glass, or other materials that can be recycled to conserve resources and reduce waste. Additionally, recycling hard drive platters ensures that any sensitive data stored on them is properly destroyed to protect your privacy and security. Be sure to use a certified electronics recycler to handle the disposal of hard drive platters responsibly.
What kind of material is used to make HDD platters?
Platters made from several material ferromagnetic and nonmagnetic material which are: 1 : perpendicular material cobalt and platinum and Cr 2: coated material Al2O3 Weight of platinum about 10 % to 35 %
What are the components of hard disk?
Most of the enclosure is made out of a metallic alloy however the main part of a hard drive, which stores the data magnetically, is called the platter. In a hard drive there are normally several platters. Platters can store data on both sides requiring a head (reader) for each side. The core of the platters are typically made using an aluminum or glass and ceramic substrate shaped into a disk. Then the disk is coated with a thin layer of a mostly nonmagnetic metallic alloy and on top of this is a protective carbon-based overcoat. Both of these layers are applied in the same process which is called sputtering. The next layer of the disk is a nanometer thin polymeric lubricant applied by dipping the disk into a solvent solution. The surface of the disk needs to be flawlessly smooth so that the disk head can rapidly move over the surface. Scott
How do the hard disk work After replacing it?
It spins for one ( at usually 7200 rpm) and writes in a language that involves 1 and 0's(Binary Code) It is a like a rewritable CD but a lot cooler A hard disk stores data in much the same way as a floppy drive, magnetic pulses are imprinted onto the surface of the disk by a read/write head which can also then read the data back. Hard disks differ from floppies in that the data can be stored in much higher densities and accessed at much higher speeds by using a non-removable disk which is sealed from contaminants. Modern hard disks usually have several disks within them (platters) and dedicated read/write heads for both sides of each. The platters themselves are usually made of some aluminum alloy coated with a thin layer of iron oxide and are very rigid. A hard disk drive (HDD), commonly referred to as a hard drive, hard disk, or fixed disk drive, is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Strictly speaking, "drive" refers to a device distinct from its medium, such as a tape drive and its tape, or a floppy disk drive and its floppy disk. Early HDDs had removable media; however, an HDD today is typically a sealed unit (except for a filtered vent hole to equalize air pressure) with fixed media.
Who is the largest manufacture of hard disk drives?
who is the largest manufacturer of memory is made up of hard disk drives
What is a computer hardrive?
A harddrive is a device that stores data which can be retrieved later by an operating system. A harddrive is commonly made with stacks of platters on which data is stored maganetically and is read by the read head (little devices that move around the platters connected by an armiture)
What are the disks in older hard drives made of?
Aluminum with a ferromagnetic oxide coating was what the hard disk was made of in older disk drives. This was SOP back in the day. Today, we still see aluminum, but we also see glass and a couple of other minor contributors. And we've moved away from iron-based magnetic media to cobalt-based. Need links? You got 'em.
What was the first ever hard disk drive?
The first hard drive was made in Silicon Vally. The hard drive was made by a company, IBM.
