How does magnetic devices read/ write data
WebIn broad terms, magnetic storage mostly works very similarly to Smith's recording. Read and write heads (either combined or separate) are used to align the magnetic fields on the … WebAll magnetic storage devices read and write data by using electromagnetism. This basic principle of physics states that as an electric current flows through a conductor (wire), a magnetic field is generated around the conductor (see Figure 8.1). Note that electrons actually flow from negative to positive as shown in the figure, although we ...

Magnetic storage or magnetic recording is the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetisation in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads. … See more Magnetic storage in the form of wire recording—audio recording on a wire—was publicized by Oberlin Smith in the Sept 8, 1888 issue of Electrical World. Smith had previously filed a patent in September, 1878 but found no … See more Analog recording Analog recording is based on the fact that remnant magnetisation of a given material depends on the magnitude of the applied field.
