Magnetic Tape Recording Materials
Abstract
The design criteria for magnetic recording tapes are considered with respect to the desirable physical and magnetic characteristics for high-resolution recording systems; in particular, the magnetic properties of the universally used iron-oxide powders are compared with possible competitive permanent magnet materials. The properties of oxide and metal powders and of metallic thin films are compared, and the possibility of their future use in high-output high-resolution tapes is also assessed in this paper.
