Abstract

The invention discloses a device applied to magnetic recording medium orientation and belongs to the field of permanent magnet materials. The device comprises a first permanent magnet device forming a first permanent magnet circuit and a second permanent magnet device forming a second permanent magnet circuit, wherein a channel is arranged between the second permanent magnet device and the first permanent magnet device, the first permanent magnet circuit and the second permanent magnet circuit are symmetrically arranged, parallel permanent magnet fields are formed in the channel, and a magnetic recording medium is orientated when passing through the channel. The device uses a permanent magnet material as a constant magnetic source, orientates the magnetic recording medium, requires no electromagnetic field and is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the field of permanent magnet materials, in particular to a device applied to the orientation of magnetic recording media. Background technique [0002] Materials that can be used as information carriers in magnetic recording technology, such as magnetic tapes, magnetic disks, and magnetic cards, are collectively referred to as magnetic recording media. At present, when the magnetic recording medium is oriented, the magnetic recording medium is generally placed in an electromagnetic field to generate magnetization under the action of the electromagnetic field, forming a perpendicular magnetic field or a parallel magnetic field. However, the electromagnetic field used in this orientation method must be provided with power supply, magnetizing equipment, etc. to realize it. Contents of the invention [0003] For the deficiencies of the prior art, an object of the present invention is to provide a device for the orientation of m...
