Grain isolated multilayer perpendicular recording medium |
摘要 |
A new type of multilayer structure is shown which has superior properties for retaining magnetic transitions on a surface as they are written by a recording transducer. The multilayer is composed of crystal grains which are electronically isolated from one another (exchange isolated). The exchange isolation of the grains creates a type of medium which can viably store data at more than 2 billions bits per square inch. A method is described for making such a structure and the storage of magnetic transitions at extremely high density is demonstrated. Recording with previous multilayer candidates is also shown for comparison purposes.
