Template:Title A hard disk drive (HDD), hard disk, or hard drive is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage and one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data even when powered off.[1]
The two types of iPods that use hard disk drives are the iPod (alternatively iPod classic), and the iPod mini. These hard disks range from 4 GB to 160 GB in capacity.
Note: The iPod nano,iPod shuffle, and iPod touch both use flash memory instead of hard drives.
