Cobalt tantalum zirconium (CoTaZr) alloy sputtering target is the key thin film material of magnetic recording material. Magnetic recording materials make use of magnetic characteristics and magnetic effects to input (write), record, store and output (read) sound, magnetic materials for information such as images and numbers. Divided into magnetic recording medium materials and magnetic head materials. The former mainly complete the information recording and storage functions, and the latter mainly complete the information writing and reading functions. In physics, these products are called magnetic recording media (only magnetic powders are considered magnetic recording materials). In the consumption structure of these products, audio tapes account for the largest proportion (see table). Magnetic recording has the characteristics of high recording density, stability and reliability, repeated use, variable time base, wide

recordable frequency range, and fast information writing and reading speeds. It is widely used in broadcasting, film, television, education, medical treatment, automatic control, geological exploration, electronic computing technology, military, aerospace and daily life.

There are three types of recording forms of magnetic recording materials:

① Longitudinal magnetic recording materials, where 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 tapes.

② Transverse 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 materials, 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, etc.

The cobalt tantalum zirconium alloy target produced by Xinkang is the key thin film material of the perpendicular magnetic recording material.
