Abstract

The invention provides a magnetic storage device which is used for storing data. The magnetic storage device comprises a magnetic storage track, a first writing device, a second writing device and a driving device, wherein both the first writing device and the second writing device are located at different positions of the magnetic storage track; the first writing device is used for writing first data or second data; the first data is expressed by a first magnetization direction of a magnetic domain; the second data is expressed by a second magnetization direction of the magnetic domain; the second writing device is used for writing third data and fourth data; the third data is expressed by a third magnetization direction of the magnetic domain; the fourth data is expressed by a fourth magnetization direction of the magnetic domain; and the first, second, third and fourth magnetization directions are different from each other.

Description

technical field [0001] The invention relates to signal processing, in particular to a magnetic storage device and an information storage method using the device. Background technique [0002] The principle of magnetic domains as the basic data recording unit in magnetic storage devices is: when a single magnetic domain is not magnetized, a small magnetized region is generated in a single magnetic domain to reduce the magnetostatic energy, and a large number of atoms in the small magnetized region The magnetic moments are aligned in one direction, but the directions of the magnetic moments of adjacent small magnetized regions are different from each other, and then cancel each other out, so that the magnetic domains do not show magnetism. However, when an external magnetic field is applied to the single magnetic domain for magnetization, when the magnetic field strength of the external magnetic field reaches a certain level, the magnetic moments of all the small magnetized re...
