Multi-color recording medium responsive to force fields and apparatus for recording on the medium

A recording medium responsive to a force field comprising:

• a continuous web member, said continuous web member being formed from a transparent material having a first plurality of capsules therein and a second plurality of capsules therein, said first and second plurality of capsules being substantially uniformly mixed throughout said transparent material,
• first force field responsive means responsive to a first force field in said first plurality of capsules, said first responsive means exhibiting a first response to incident electromagnetic radiation,
• second force field responsive means responsive to a second force field in said second plurality of capsules, said second responsive means exhibiting a second response different from said response of said first responsive means to incident electromagnetic radiation, said first and said second force field responsive means each including highly reflective, and flake-like particles suspended within said capsules and being selectively orientable by an applied force field from a first position wherein flake-like particles scatter incident electromagnetic energy into said continuous web member into a second position wherein said flake-like particles reflect incident wave lengths of electromagnetic energy from said continuous web member thus forming a contrast between areas of said continuous web member having particles in said first orientation from areas of said continuous web member having particles in said second orientation in accordance with said first and second response to incident electromagnetic energy.
