Tape drive and hard disk drive
A magnetic storage device is a device that uses a magnetic head to read and write data to and from a magnetizable medium. The medium can be as basic as a plastic tape that is coated with fine particles of a metal, such as is found in audio recording and tape storage devices.
Hard Disk
It is a data storage medium
Magnetic discs are a storage medium that uses magnetic materials to store data. Common examples include hard disk drives (HDDs) and floppy disks. Magnetic discs are commonly used in computers and other electronic devices for data storage and retrieval.

CD-ROM
A hard disk drive is a type of magnetic storage device. A magnetic storage device stores data on a magnetized medium. Other types of magnetic storage includes magnetic recording tapes and the stripes on credit cards.
To store data using magnets, you can use magnetic storage devices like hard drives or magnetic tapes. These devices use tiny magnets to represent binary data as either a 0 or 1. When writing data, an electromagnetic write head changes the magnetization of the storage medium, and when reading data, a read head detects the magnetic fields to interpret the stored information.
For what storage medium are phase change alloys used?
RAM is a primary storage medium, but it is volatile. Cache memories storage frequently accessible data.
A medium is the base substance for some task or experiment. Storage media include any technological devices used to store, keep and retrieve data (information).
