Magnetic Disks, otherwise known as 'Floppy disks'. The last generation of these disks were 3 1/2" and used a ridgid plastic case, to contain the magnetic disk within. Not very floppy. The early versions were 7" and 5" and were contained in soft plastic outer sleeves. These were actually floppy.
It is the magnetic elements in a magnetic disk that are used to store information.
This describes a hard disk drive (HDD), which contains one or more rigid circular platters coated with magnetic particles used to store data. The data is written, read, and erased magnetically using a read/write head.
Magnets have a north and south pole. The read/write head can flip the polarity on a small portion if the magnetic surface to store data. The north and south poles make the binary 1s and 0s the computer understands.
Magnetic tape is used to store music in old cassettes
A magnet can affect a video tape because the tape is coated with a magnetic material that stores information in the form of magnetized particles. When a strong magnet is brought close to the tape, it can disrupt or erase the magnetized particles, leading to loss of data.
Hard disk drives use a magnetic coating of iron oxide to store data because it can be easily magnetized to represent binary data (0s and 1s). The magnetic polarity of the iron oxide particles can be changed by a magnetic head, allowing data to be written and read from the disk.
An electromagnet can cause a cassette tape to be erased or distorted because the magnetic field produced by the electromagnet interferes with the magnetic particles on the tape that store the audio data. This interference can lead to the loss of recorded information or a degradation in sound quality. It's important to keep magnetic tapes away from strong magnetic fields to avoid damage.

you first have to go to items, then go to the scrool bar and the first part of the bar is "store items"
