Application of PVD Vacuum Sputtering Coating machine in Magnetic Recording Media Industry:
Magneto-optical recording media mainly include magnetic recording media and optical recording media, which are coated by pvd vacuum sputtering coating machine process. Among them, the optical recording medium has different coating requirements according to the type and function of the disc.
The process of repetitive read-write discs is the most complicated and requires three layers of coating, namely the reflective layer, the dielectric layer and the recording layer; the rest of the discs only need to be plated with a reflective layer or a semi-reflective layer.
1. pvd Vacuum sputtering coating machine of magnetic recording media
The pvd sputtering coating equipment of magnetic recording media requires sputtering targets with low gas content, high purity, fine-grained microstructure, high magnetic penetration and utilization, uniform metallography, and excellent electrical and mechanical properties.
2. Vacuum sputtering coating of optical recording media
The pvd vacuum sputtering coating machine of optical recording media requires sputtering targets with good sputtering efficiency, film characteristics, crystal image uniformity, cleanliness, and recycling system characteristics.
