Abstract: A powder comprising flakes of magnetically soft amorphous alloy having an average thickness of 0.01-1 .mu.m and an aspect ratio of 10-10,000 is blended with a binder to form a coating composition from which a magnetic shield is fabricated. The alloy is basically an Fe-B-Si ternary alloy in which iron may be partially replaced by another metal.

Abstract: A magnetic medium for magnetic embossment comprises a main magnetic layer and a high permeability magnetic-metal layer, a nonmagnetic white metal layer and a coloring layer laminated on the main magnetic layer.A magnetic card comprises a card substrate which is nonmagnetic, and a magnetic medium for magnetic embossment disposed on at least a part of the card substrate, which magnetic medium comprises a main magnetic layer and a high permeability magnetic-metal layer, a nonmagnetic white metal layer and a coloring layer laminated on the main magnetic layer.

Abstract: A magnetic recording reproducing apparatus is made ready to operation by insertion thereto of a pack housing an endless recording medium. When a magnetic card is inserted into the apparatus with the pack inserted thereto, the contents, informations or data recorded on the magnetic card are read out and recorded on the endless recording medium and then the recorded contents, informations or data are reproduced from the endless recording medium. After passage of the magnetic card through the apparatus, the reproduction from the endless recording medium will repeatedly continue. When a magnetic card is inserted into the apparatus without any pack inserted thereto, a direct reproduction from the magnetic card is performed.

Abstract: The recorded content of a magnetic card is transferred directly to a magnetic tape simply by bringing the magnetic card into contact with the magnetic tape and applying a magnetic field to the contacting area with the aid of a copy magnet or a magnetic printing head energized by D. C. current or A. C. current, on the condition that the coercive force of magnetic material on the card is larger than that on the tape, and a reproducing head mounted along the path of the tape reproduces the transferred content. Thus, the recorded content of a magnetic card can be reproduced many times just by engaging the card in the device once.

Abstract: A demodulation system for digital information, recorded by an FM or PM system, which provides a clock output pulse whose pulse width is proportional to the time length of the preceding bit frame and said clock output signal is utilized for demodulating the recorded data. Said pulse width can be controlled either by an analog or a digital circuit and thus, the present invention has the advantage that the information is demodulated stably though the moving speed of the recording medium is changed or deviated.
