How did the hard disk get its name?
The first discs that were made for computers were made from a thin material that bent easily. These were referred to as floppy disc then a smaller disc with a hard plastic cover was brought out to replace this which was originally meant to be referred to as a hard disc, however at around the same time the discs that computers ran on were also looking for a name and these ended up being called the hard disc and the new rigidly encased discs went back to being referred to as floppy discs.

How is magnetism used in a computer?
Magnetism is used to operate the fan motors and the disk drive motors as well as operating the "voice coil" that causes the disk read/write heads to move. The surfaces of the hard disk "media" is magnetized to represent data. The hard disk read/write heads are nothing more than small electromagnets and as the heads move across the spinning disk media, magnetic data is sent or received by the disk heads. Older computers used a magnetic "core" to store data. That's the origin of the term, "core memory". With the decrease in cost ind incredible speed of transistor based memory, nobody uses magnetic core any more.

What must happen before any data can be read or written on a hard disk?
the right place on the hard disk has to be found, then the read/write head must be placed there, then the sector (a small part of the hard disk) is read or written, if it's read, the data is moved into the memory, maybe by the DMA (Direct Memory Access) Controller. Is it's a write operation, the data must first be given to the Hard Disc Controller.
What is the correct spelling for computer disc drive?
"Disc" refers to optical media, such as CDs or DVDs. "Disk" refers to magnetic media, such as hard drives. So the answer depends on which drive you are referring to; most have both an "optical disc drive", and a "hard disk drive".
