Abstract

A method and an apparatus for nozzleless magnetofluidic recording are disclosed in which a magnetofluidic material is arranged on the surface of a support member disposed oppositely to a recording surface, and by applying a magnetic force to the magnetofluidic material, the magnetofluidic material is protruded on the support member. Further, the magnetofluidic material is subjected to a coulomb force or a magnetic force and transferred from the protruded part to the recording surface, thereby producing an image on the recording surface.
