Abstract: A silicon body has an array of nozzles therein and a separate magnet for each nozzle integral with the body. The magnet is disposed adjacent the nozzle with which it cooperates so that it can apply a deflection, prior to break-up of the stream exiting from the nozzle into droplets, to selected portions of the stream. The droplets, which are formed from the selected portions having the magnetic deflection applied thereto from the magnet cooperating with the nozzle, deflect to a gutter and are not applied to a recording surface, which moves orthogonal to the nozzles. If desired, the winding of the magnet can have a second excitation frequency supplied thereto to break up the stream into droplets. The break-up of the stream into droplets also can be accomplished by vibrations produced by a piezoelectric transducer, for example.

Abstract: A scanner transfers information in the form of magnetic characters to a soft magnetic film, and subsequently transfers the information to a storage medium, such as disc, tape, or the like. Use of amorphous and other bubble material is suggested. A bias field is coupled through the magnetic characters to the material in which bubbles are generated and transported.

Abstract: METHOD AND APPARATUS FOR APPLYING MAGNETIC LIQUID DROPLETS TO A RECORDING SURFACE of the disclosure A stream of magnetic ink droplets is directed towards a recording surface and initially passes through a selector, which selects the droplets for application to the recording surface to form characters thereon. Each of the selected droplets passes through first and second magnetic deflectors in which each of the selected droplets is deflected in directions orthogonal to each other and orthogonal to the direction in which the droplets are moving toward the recording surface. Each of the selected droplets is subjected to a magnetic field gradient varying with respect to time during the passage of the droplet through one or both of the magnetic fields depending on the desired position of the droplet on the recording surface relative to the prior droplet.
