A method of writing data on magnetic stripe of a smart card by imposing a magnetic field of a given polarity on each selected segment of the magnetic stripe, such that data on the magnetic stripe can be read by a magnetic card reader and interpreted as digital bits. The method includes providing a multi-dimensional conductor array placed proximate to the magnetic stripe, the number of conductors in the array is considerably smaller than the number of segments, and each segment is associated with two or more conductors. The method further includes providing current drivers for sending currents in a controlled direction through the conductor array. The system further includes sending currents, using said current drivers, through conductors of the array, such that for each one of the selected segment composite currents flowing through its associated two conductors overcome the coersivity of the segment on the magnetic stripe.

An article of manufacture includes a substrate, a first patterned layer deposited on the substrate in a first region, and a second patterned layer deposited on the substrate in a second region. The first patterned layer encodes first information in first symbols that are detectable by an optical sensor. The second patterned layer encodes second information in second symbols that are detectable by a non-optical sensor. The second information is distinct from the first information and the second region at least partially overlaps the first region.

A secrecy management information recording device has an information input section which inputs image information printed by a printer and secrecy management information corresponding to the image information, a transport mechanism which receives a printing sheet on which the image information has been printed by the printer, and discharges the sheet after passage over a heat generating resistor, and a magnetic tag forming section which controls generation of heat by the heat generating resistor according to content of the secrecy management information corresponding to the image information printed on the transported printing sheet to thermally transfer at least one magnetic member contained in a thermal transfer sheet onto the printing sheet. A magnetic tag representing the content of the secrecy management information is thereby formed on the printing sheet. This device records additional information corresponding to image information on a printing medium at the time of copying of the image information to the printing medium in such a manner that the additional information is remotely readable.

The present invention provides a card recording apparatus capable of printing in high speed as well as reducing overall dimensions of the apparatus. After a card is transported to an information recording section 200 in a lateral (short length) direction of the card, an information signal is recorded on the card thereby. Then, the card is transported to a second heating section 300. An ink image formed on an intermediate recording medium 7 by a first heating section 500 is re-transferred to the card by the second heating section 300. A warp developed on the card by the second heating section 300 is corrected by a card warp correcting section 400.

Nanoparticles of intermetallic alloys such as FeAl, Fe3Al, NiAl, TiAl and FeCoV exhibit a wide variety of interesting structural, magnetic, catalytic, resistive and electronic, and bar coding applications. The nanosized powders can be used to make structural parts having enhanced mechanical properties, magnetic parts having enhanced magnetic saturation, catalyst materials having enhanced catalytic activity, thick film circuit elements having enhanced resolution, and screen printed images such as magnetic bar codes having enhanced magnetic properties. In contrast to bulk FeAl materials which are nonmagnetic at room temperature, the FeAl nanoparticles exhibit magnetic properties at room temperature.

The invention discloses a magnetic ink reading device and a printer. Even if the pressing force of the medium to the magnetic detection head is increased, there is no deformation on the medium, and a stable reading operation can be performed. The magnetic ink reading device has a conveying Mechanism, magnetization mechanism, magnetic detection head, roller parts and rotating shaft. The transport mechanism transports the sheet-like medium printed with magnetic ink along the transport path. The magnetizing mechanism magnetizes the magnetic ink of the medium on the transport path. The magnetic detection head is arranged near the magnetizing mechanism along the transport path, and reads the magnetism of the magnetized magnetic ink. The roller member is formed in a cylindrical shape, is disposed opposite to the magnetic detection head across the conveyance path, presses the medium conveyed along the conveyance path against the magnetic detection head, and rotates along the surface of the medium. The rotating shaft rotatably supports the roller member, and is in contact with the inner wall portion of the roller member at the center portion in the axial direction of the roller member.
