The search for 3D (Three Dimensional) computer memories has intensified in the last year since the realization that 2D recording was approaching saturation.
Magneto-optical (MO) recording [1,2,3,4] is a particularly suitable technology since most MO alloys are amorphous and can be deposited in thin film form on single crystal silicon. This note reports on the feasibility of a novel 3D memory consisting of a high-speed silicon short-term cache memory and a long-term high density MO memory. This hybrid memory requires a suitable channel code. A RLL (run length limited) code [5] offers better dc stability, accurate timing synchronization and can support a higher ...
