1981 by a group of scientists who found out the properties of a disc magnet
It is the magnetic elements in a magnetic disk that are used to store information.
A layer of iron oxide enables data to be saved as a sequence of different magnetic alignments representing ones and zeros.

Digital information is stored in microscopic needles as part of the disk's magnetic coating.
In a way, yes. The material that makes up the "disk" in a floppy is Mylar, a magnetic substance. Data is stored on the Mylar disk in the form of magnetic charges.
A disk drive.
No, aluminum is not magnetic and cannot exhibit magnetic properties.

Yes, data is written to and read from a floppy disk using a magnetic read/write head that interacts with the magnetic coating on the disk. When writing data, the magnetic head aligns the magnetic particles on the disk surface to represent the information. When reading data, the head detects the magnetic orientation of the particles to retrieve the stored information.
