ABSTRACT A multi-color recording medium responsive to a magnetic or an electrostatic recording field for recording an input signal thereon and having a continuous web of a transparent encapsulat- ing material containing a suspension of highly reflective flakes with these flakes being selectively orientable between two in- cident light reflecting states. These flakes are distributed in individual micro-capsules with each capsule having a pre- determined response to an applied force field to allow orienta- tion of the suspended particles therein from one light reflecting state to another.
