Hard disk drives are a highly popular medium of computer storage because of their enormous capacity compared to other media. As a disadvantage, they are more costly and, depending on the type, have a limited lifetime.
Disk platters are the circular data storage components inside hard disk drives (HDDs) and some solid-state drives (SSDs) that store digital information. Each platter is coated with a magnetic material that allows data to be written and read by a read/write head. Multiple platters can be stacked within a single drive to increase storage capacity. The speed and performance of a hard drive are influenced by the number of platters and their rotational speed.
The circular disk inside a hard drive is called a platter. Platter surfaces are coated with a magnetic material that allows data to be stored and retrieved by read/write heads as the platters spin at high speeds. Multiple platters can be stacked in a single hard drive to increase storage capacity.
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.
A hard disk drive (HDD) uses aluminum platters to store data. These platters are coated with a magnetic material, allowing data to be written and read by read/write heads that move across the surfaces. HDDs are commonly used for both personal and enterprise-level data storage due to their capacity and cost-effectiveness.

Hard Disk Drive, Floppy Drive
I just got this exact same question for homework in my CS course today, what a surprise. A floppy disk, magnetic coated and rotates.
The concentric circular bands on a hard disk where data is stored are called tracks. Each track is divided into smaller units called sectors, which are the basic storage units for data. The arrangement of tracks and sectors allows for efficient data retrieval and organization on the disk's platters. The read/write head moves across these tracks to access or store information as needed.
A hard disk drive consists of one or more thin disks that spin at high speed (1200 to 15000 rpm) while magnetic heads read data from them, hovering extremely close to them without making contact.
