Magnetic storage is a term from engineering referring to the storage of data on a magnetised medium. Magnetic storage was first suggested by Obeline Smith in 1888. The first magnetic recorder was invented by Valdemar Poulsen in 1895. Engineering is the application of scientific and technical knowledge to solve human problems. ... Data is the plural of datum. ... Magnetic field lines of a bar magnet shown by iron filings on paper A magnet is an object that has a magnetic field. ... Obeline Smith first suggested magnetic storage in 1888. ... 1888 (MDCCCLXXXVIII) is a leap year starting on Sunday (click on link for calendar) of the Gregorian calendar or a leap year starting on Tuesday of the Julian calendar. ... Valdemar Poulsen (1869 - 1942) was a Danish engineer. ... 1895 (MDCCCXCV) was a common year starting on Tuesday (see link for calendar) of the Gregorian calendar (or a common year starting on Thursday of the 12-day-slower Julian calendar). ...
The read/write heads in magnetic storage record data in the form of magnetized spots on iron oxide coatings.
Media types that exploit magnetic storage include hard disk and floppy disk drives, zip drives and various tape drives, video cassettes and audio cassettes, magnetic core memory, thin film memory and drum memory.

A new type of magnetic storage, called MRAM, is being produced that stores data in terms of polarity rather than electric charge. The advantage to this is that it will require far less electricity and will still remain intact in case of a crash. Magnetoresistive Random Access Memory (MRAM) is a non-volatile computer memory (NVRAM) technology, which has been in development since the 1990s. ... Data is the plural of datum. ... layers]] that separate organs or subcompartments in organisms. ... â¹ The template below has been proposed for deletion. ... Lightning strikes during a night-time thunderstorm. ...

Magneticstorage media are permanently magnetized in a direction (North or South) determined by the writing field.
When a magneticstorage medium (a spinning computer disk, for example) is put in close proximity with the writing head, the "hard" magnetic material on the disk surface is permanently magnetized (written) with a polarity that matches the writing field.
Magneticstorage devices such as disk drives are commonly ranked according to their ability to store significant quantities of computer data in a very small region.
