COMPUTER FUNDAMENTALS

Detailed explanation-1: -User data is encoded using an encoding scheme, such as run-length limited encoding, which determines how the data is represented by the magnetic transitions. A typical HDD design consists of a spindle that holds flat circular disks, called platters, which hold the recorded data.

Detailed explanation-2: -Unsourced material may be challenged and removed. A hard disk drive platter or hard disk is the circular magnetic disk on which digital data is stored in a hard disk drive. The rigid nature of the platters is what gives them their name (as opposed to the flexible materials which are used to make floppy disks).

Detailed explanation-3: -Hard drive platters are circular disks that store data on a hard drive. They are made of metal or glass and are coated with magnetic material. The data is stored on the platters as tiny magnetic particles. The platters are spinning at high speeds inside the hard drive and are read by the head, which is like a needle.

Detailed explanation-4: -A typical HDD design consists of a spindle which holds one or more flat circular disks called platters, onto which the data are recorded. The platters are made from a non-magnetic material, usually aluminum alloy or glass, and are coated with a thin layer of magnetic material.
