Some Design Criteria for Magnetic Tape

Document Thumbnail

The characteristics of a magnetic-recording system depend, among other things, upon the magnetic properties of the recording tape and the intensity of the supersonic recording bias. In general, increasing the bias signal results in an increase in the depth of the recording into the tape and poorer response at short wavelengths. Therefore, the coating thickness and the bias intensity are related in their effect upon overall frequency response. Tape coatings having high magnetic-remanence properties are superior (especially at long wavelengths) to conventional coatings. Orientation of the magnetic particles in the tape coating is shown to be beneficial. Consideration of these and other basic principles facilitates the design of tapes having optimum properties for specific recording applications.
