铁钴钽合金作为新型的垂直磁记录材料在今后的高密度记录中将有广阔的发展前

As a new type of perpendicular magnetic recording material, iron-cobalt-tantalum alloy will have broad development prospects in the future high-density recording. There are three recording forms of magnetic recording materials: ① Longitudinal magnetic recording materials. The signal magnetization direction recorded on the surface of the magnetic layer is consistent with the movement direction of the recording material, such as audio tape. ②Transverse magnetic recording materials, the signal magnetization direction recorded on the surface of the magnetic layer is perpendicular or close to the direction of movement of the recording material, such as video tapes. ③Perpendicular magnetic recording material, where the signal magnetization direction recorded on the surface of the magnetic layer is perpendicular to the surface of the recording material, such as magneto-optical disks. Since the development of magnetic recording materials, the recording wavelength has been shortened from the original 1000μm to below 1μm, and the Hc has increased from 102Oe to more than 103Oe. The most widely used materials are oxide magnetic powder and alloy magnetic powder.

As a new type of perpendicular magnetic recording material, Fe Co TA alloy will have broad development prospects in high-density recording in the future. There are three recording forms of magnetic recording materials: ① longitudinal magnetic recording materials. The magnetization direction of the signal recorded on the surface of the magnetic layer is consistent with the movement direction of the recording material, such as recording tapes. ② Transverse magnetic recording material: the magnetization direction of the signal recorded on the surface of the magnetic layer is perpendicular or nearly perpendicular to the moving direction of the recording material, such as video tape, etc. ③ Vertical magnetic recording material: the magnetization direction of the signal recorded on the surface of the magnetic layer is perpendicular to the surface of the recording material, such as magneto-optical disc, etc. With the development of magnetic recording materials, the recording wavelength has changed from the original 1000 μ M shortened to 1 μ Below m, HC increases from 102oe to more than 103oe. The most widely used materials are oxide magnetic powder and alloy magnetic powder.
