What Is a Magnetic Drum?

In 1953, the first magnetic drum was applied to the IBM 701, which was used as internal memory. The magnetic drum uses magnetic materials coated on the surface of the aluminum drum to store data. The drum rotates at a high speed, so the access speed is fast. It uses saturated magnetic recording, which has developed from a fixed magnetic head to a floating magnetic head, and from a magnetic glue to a continuous magnetic medium using electroplating.

The drum memory is characterized by fast response.

Among the problems in the development of China's magnetic drum component industry, many situations are not optimistic, such as irrational industrial structure and industry concentration on labor-intensive products; technology-intensive products lagging significantly behind developed industrial countries; the decisive role of production factors is weakening; industrial energy Large consumption, low output rate, serious environmental pollution, and great damage to natural resources; the overall size of the enterprise is small, the technological innovation capacity is weak, and the management level is backward.

From what angle is the development of China's magnetic drum component industry analyzed? In what way do you evaluate the development of the Chinese drum assembly industry? What is the development orientation and prospect of China's magnetic drum component industry? What is the correlation between the development of China's magnetic drum component industry and the current economic hotspot issues ... and so on, all are issues that must be faced and solved in the development of the magnetic drum component industry-the development of the Chinese magnetic drum component industry has reached a fork; the production of the Chinese magnetic drum component industry Enterprises urgently need to choose a development direction.

The development report of China's magnetic drum component industry expounded the development history of the world's magnetic drum component industry, analyzed the development status and gaps of the Chinese magnetic drum component industry, and pioneered the concept of the "new-type magnetic drum component industry" and the alternative industry. On this basis, the meanings of "new-type drum assembly industry" and alternative products are accurately defined from four dimensions: "people-oriented", "technology innovation", "environment-friendly" and "future-oriented".
