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.
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.
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.
There are two types of Hard disk. 1:Sea gate disk 2:SATA Hard disk
