The magnetic properties of a disk depend on its material composition and structure. In general, a magnetic disk can exhibit ferromagnetism, where magnetic domains align to produce a net magnetic moment, or paramagnetism, where magnetic moments align weakly in an external magnetic field. The orientation of the disk and the presence of any magnetic treatments can also influence its magnetic behavior, such as coercivity and remanence. Additionally, the geometry of the disk can affect the distribution of magnetic fields around it.

magnetic disk
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.
Allan Shugart invented the first floppy disk in 1967 which was 8 inches in diameter.
A disk drive.
Lynott was part of the team that invented the magnetic disk drive - basically, he helped invent the computer hard drive.
