Tsinghua Tongfang is a well-known computer enterprise in China, which produces high-quality optical discs with good stability and durability. Ziguang is an integrated circuit manufacturer, and its main business is not CD production, so the quality of CD may not be as good as that of Tsinghua Tongfang.

In addition to the brand, the quality of the CD is also related to factors such as production technology and materials. When selecting optical discs, we should pay attention to selecting products with advanced production technology and high quality materials to ensure the safety and stability of data.
