WebJun 11, 2024 · Per bit, magnetic core memory was cheaper, smaller, and lighter than the vacuum-tube or transistor memory of that era. Aerospace companies also liked its nonvolatile nature and resistance to radiation. Over 2,000 core memories flew in aircraft or spacecraft by 1978. *Computers in Spaceflight: The NASA Experience, p. 90

An examination of the usage and error records of over one million used … 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 … 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 surface. The read-and-write head is used to detect and modify the magnetisation of … 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.
