It is stored as magnetic impulses, similar to how a tape recorder records, except that the data is digital rather than analog.
Yes, there are some surprisingly strong magnets in the Hard Disk Drive. The read/write "head" also is an electromagnet, and the "platter" (spinning disk) is magnetized, but over all not very magnetic.
what information is normally stored in client files and what is it used for
as pits and landsInformation is stored in bits on a CD. Bits are stored as a sequence of 0s and 1s.
Permanant information is stored in hard drives, usb drives, cds, dvds and the temporary information is stored in RAM (Random Access Memory).
Information is stored in the computer's hard drive, which is a magnetic disk read by lasers.
Information on magnetic cylinders, such as those used in tape drives or magnetic storage devices, is stored in the form of magnetic patterns. These patterns represent binary data, with the magnetic orientation of small regions on the surface of the cylinder indicating either a 0 or a 1. As the cylinder rotates, a read/write head detects these magnetic patterns to read or write information, allowing for data retrieval and storage. The density of these magnetic patterns determines the amount of information that can be stored on the cylinder.

The magnetic strip holds the information of your card.
Magnetic drum memory or magnetic drum storage, a type of computer memory/storage that is now long obsolete.
Any information you want.
Digital information is stored in microscopic needles as part of the disk's magnetic coating.
Data may be stored on tape in both analog and digital form.But if the recording medium is magnetic tape, then the data willl be stored as magnetic patterns.Cuneiform, writing on paper, and wax cylinders are all long-lasting storage media.Magnetic media have yet to prove themself as archival storage. The same comment applies to many of the CD and DVD materials.
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.
A card reader, also known as a magnetic stripe reader, is used to read the information stored on the magnetic strip of a credit card. The reader uses a magnetic head to detect and decode the data on the strip, such as the card number and expiration date.
It sounds like you might be referring to a device called a magnetic card reader, which reads information stored on magnetic stripes found on credit cards, IDs, and other types of cards. These readers use magnetic fields to interpret the data encoded on the magnetic stripe and typically interface with a computer or other device to process the information.
