Magnetic data storage (Chapter 15) - Magnetic Materials
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. Magnetic storage … 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 … 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. The magnetic material is normally in the form of tape, with the tape in its blank form being initially … See more Magnetic disk heads and magnetic tape heads cannot pass DC (direct current), so the coding schemes for both tape and disk data are designed to minimize the DC offset. … See more A new type of magnetic storage, called magnetoresistive random-access memory or MRAM, is being produced that stores data in … See more Information is written to and read from the storage medium as it moves past devices called read-and-write heads that operate very close (often tens of nanometers) over the magnetic … See more Access method Magnetic storage media can be classified as either sequential access memory or random access memory See more As of 2024 , common uses of magnetic storage media are for computer data mass storage on hard disks and the recording of analog audio and video works on analog tape.
