It is a data storage medium
A hard drive.
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.
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.
For what storage medium are phase change alloys used?
Magnetic storage optical storage solid-state storage storage capacity
Tape drive and hard disk drive

Optical Storage Medium
the magnetic storage devices, use magnetic property of the materials to save data in bits.
Magnetic storage:Yes magnetic tapes are permanent storage and are the best permanent storage. These are very slower storage but are very cheap storage then RAM or other kind of memory.
Yes; if the storage is on magnetic media then that can be altered by magnetic and electric fields.
