Detailed explanation-1: -A spindle is a shaft that holds rotating hard disk drive (HDD) platters in place. The term is also often used to refer to a single HDD. Spindle speed, measured in rotations per minute (RPM), is one metric used to gauge disk drive performance.
Detailed explanation-2: -A typical HDD design consists of a spindle that holds flat circular disks, called platters, which hold the recorded data.
Detailed explanation-3: -Platter-This is the vinyl record, so to speak; the disk that contains the sectors and tracks (all the info). 2. Spindle-This is the core that runs the platter and determines the speed of the spinning, measured in revolutions per minute (rpm).
Detailed explanation-4: -A platter is a circular magnetic plate that is used for storing data in a hard disk. It is often made of aluminum, glass substrate or ceramic.
Detailed explanation-5: -The platters are made from a non-magnetic material, usually aluminum alloy or glass, and are coated with a thin layer of magnetic material. Older disks used iron(III) oxide as the magnetic material, but current disks use a cobalt-based alloy. A cross section of the magnetic surface in action.
