Magnetic Storage
by Gabriela Martinez
1. Domain propagation memory Domain propagation memory is also called bubble memory. The basic idea is to control domain wall motion in a magnetic medium that is free of microstructure
2. Magneto-optical recording Magneto-optical recording writes/reads optically. When writing, the magnetic medium is heated locally by a laser, which induces a rapid decrease of coercive field
3. Digital recording Instead of creating a magnetisation distribution in analog recording, digital recording only needs two stable magnetic states, which are the +Ms and -Ms on the hysteresis loop.
4. Analog recording is based on the fact that remnant magnetisation of a given material depends on the magnitude of the applied field
5. is the storage of data on a magnetised medium
6. Magnetic recording classes[
7. Magnetic storage uses different patterns of magnetisation in a magnetisable material to store data and is a form of non-volatile memory
