Abstract
One possible way to increase magnetic storage capacity is to move from current 2 dimensional (2D) recording mechanism to 3D recording mechanism. This paper reports the authors’ efforts towards 3D recording by a double layered disk media. The top data storage layer is perpendicularly oriented and written with lower writing current. The second data recording layer is longitudinal oriented and works at higher writing current. The transitions formed over the two layers are of a large skew angle and the reading interference between the two layers can be reduced significantly. As a result, independent reading from the two layers is realized.
