Any information you want.
Information is stored in the computer's hard drive, which is a magnetic disk read by lasers.
The magnetic strip holds the information of your card.

Digital information is stored in microscopic needles as part of the disk's magnetic coating.
It is stored as magnetic impulses, similar to how a tape recorder records, except that the data is digital rather than analog.
The principle of magnetic recording and reproduction involves encoding information onto a magnetic medium using changing magnetic fields. When recording, information is stored as magnetic patterns on the medium. To reproduce the information, a magnetic head reads the patterns and converts them into electrical signals for playback. The sketches would show the process of writing and reading magnetic data on a medium using a magnetic head.
Yes.
This sounds like a test question. This is not a good way to get an answer.
For both the magnetic and electric (static) fields, energy is considered to be stored in the field.
i dont know In case of magnetic storage, randomly distribuited tiny magnets present in the magnetic coating gets aligned according to the frequency and voltage levels of the information/data to be stored, thus leaving a magnetic signature of the information fed in electrical form. In case of optical storage bumps and pits are created on the medium to distinguish the variations in the signal to be stored with the help of laser beam. Depth and length of the pits corresponds to the change in information.
A write head is the part of an electromechanical device which converts electrical signals into digital or analogue information stored on a magnetic or optical medium.
