Yes
It is the part that attached to magnet in HDD.
Hard disk
Hard disk has always been a hard piece of ferromagnetic metal, while the floppy disk contains only one flexible magnetic foil.
Hard disk platters are typically made of a thin layer of metal, such as aluminum or glass, coated with a magnetic material that stores data.
Magnetic HARD Disk Drive constitutes of a Disk Platter, Spindle Motor, Read Write Head, Logic Card and Metal Casing with connector.
Computer hard disk drives may be made of a stack of one or more disks (made out of metal or ceramic) covered in a magnetic "paint". Each of these disks is called a "platter".
A CD is a small removable and portable plastic based disk with a thin layer of metal that reflects the laser that reads it. The hard disk is solid metal and spins inside a reader that uses a magnetic field to read the data. It is sensitive to damage and can easily be destroyed just by dropping it.
A computer hard disk or hard drive (fixed disk) is hardware.
Clusters are the smallest segments within disk sectors.Tracks are concentric circles on the hard drive.Pie-shaped wedges on the hard drive are called sectors.Platters are round, thin plates of metal that make up a hard drive.
A hard disk drive (HDD) is a fixed storage device that consists of one or more rigid metal platters coated with a metal oxide material. These platters store digital data magnetically and are read/write heads access data on the platters.
Hard Disk Drive.
IDE hard disk, SCSI hard disk, SATA hard disk, External hard disk, it is also differ by RPM speed for the HADD. I hope that helpes.
The history of hard disk is that, hard disk is invented in 1950's that time hard disk size is 20 inche's maximum the name of hard disk inventer is "REY JOHNSON" by the help of IBM team. ""BILAWAL ABBAS""
