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

摘要

The magnetic separation apparatus according to the present invention can sol ve 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 t o 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.
