Magnetic storage media, primarily hard disks, are widely used to store computer data as well as audio and video signals. In the field of computing, the term magnetic storage is preferred and in the field of audio and video production, the term magnetic recording is more commonly used. The distinction is less technical and more a matter of ...
Data storage is the recording (storing) of information in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media. Biological molecules such as RNA and DNA are considered by some as data storage. [1] [2] Recording may be accomplished with virtually any form of energy. Electronic ...
A magnon torque device was invented and later perfected at the National University of Singapore's Electrical & Computer Engineering department, which is based on such potential uses, with results published on November 29, 2019, in Science. A magnonic crystal is a magnetic metamaterial with alternating magnetic properties. Like conventional ...
Biomagnetism is the phenomenon of magnetic fields produced by living organisms; it is a subset of bioelectromagnetism. In contrast, organisms' use of magnetism in navigation is magnetoception and the study of the magnetic fields' effects on organisms is magnetobiology. (The word biomagnetism has also been used loosely to include magnetobiology ...
Drum memory – a magnetic data storage device used as the main working memory in many early computers; i-RAM – a DRAM-based solid-state storage device produced by Gigabyte, operating as a SATA hard disk drive; Magnetic storage – the concept of storing data on a magnetised medium using different patterns of magnetisation
Such storage devices may refer to removable media (e.g. punched paper, magnetic tape, floppy disk and optical disc), compact flash drives (USB flash drive and memory card), portable storage devices (external solid-state drive and enclosured hard disk drive), or network-attached storage.
The basic concept of using the square hysteresis loop of certain magnetic materials as a storage or switching device was known from the earliest days of computer development. Much of this knowledge had developed due to an understanding of transformers , which allowed amplification and switch-like performance when built using certain materials.
Magnetic storage, the storage of data on a magnetized medium; Magnetic-core memory, an early form of random-access memory; Remanence, or residual magnetization, the magnetization left behind in a ferromagnet after an external magnetic field is removed; Rock magnetism, the study of the magnetic properties of rocks, sediments and soils
