MAGNETIC SEPARATION APPARATUS, MAGNETIC DISK AND METHOD OF FORMING MAGNETIC DISK

摘要

The magnetic separation apparatus according to the present invention can solve the problem of the most-outside magnetic disk involved in a conventional magnetic separation apparatus. Further, it can simply solve the problems such as the leakage of the magnetism and the deformation of the most-outside magnetic disk. Furthermore, the performance of absorbing the magnetic floc is not decreased. In addition, according to the magnetic disk and the method of forming the magnetic disk according to the present invention, the problem of distortion in a conventional magnetic disk can be solved, and rigidity can be secured while weight saving can be attained.
