Products Process

Product Introduction

Magnetic Recording Material is Magnetic material that use Magnetic properties and Magnetic effects to input , record, store, and output information, such as sounds, images, figures, etc.The former mainly completes the information recording and storage function, and the latter mainly completes the information writing and reading function.In physics, these products are called magnetic recording media (only magnetic powder is considered magnetic recording materials).

In the consumption structure of these products, audio tapes account for the largest proportion (see chart).Magnetic recording has the characteristics of high recording density, stable and reliable, repeatable use, variable time reference, wide frequency range, fast information writing and reading.Widely used in broadcasting, film, television, education, medical treatment, automatic control, geological exploration, electronic computing technology, military, aerospace and daily life.

The recording form of the magnetic recording material is divided into two types: 1. longitudinal magnetic recording material, and the magnetization direction of the signal recorded on the surface of the magnetic layer coincides with the moving direction of the recording material, such as an audio tape. 2.transverse magnetic recording material, the direction of signal magnetization recorded on the surface of the magnetic layer is perpendicular to or close to the direction of movement of the recording material, such as a video tape. 3 perpendicular magnetic recording material, the direction of signal magnetization recorded on the surface of the magnetic layer is perpendicular to the surface of the recording material, such as a magneto-optical disk. The CoTaZr target produced by Xinkang is the key film material for perpendicular magnetic recording materials.

The picture below are two micrographs of our CoTaZr(90:5:5at%) alloy sputtering target, the average grain size＜50μm

We produce high-purity CoTaZr sputtering targets, which have the greatest advantages of high magnetic permeability and uniform grain. Below form is a typically certificate of analysis for 3N5 high purity CoTaZr(90:5:5at%) sputtering target.The analytical methods used are: 1. Analysis of metal elements using ICP-OES; 2. Analysis of gas elements using LECO.
