Inventor: MAENO TAKASHI
IPC: G06K19/06
Filed: 1992-06-15
Abstract: PURPOSE:To make ID information incapable of being illegaly rewritten by magnetically recording plural pieces of ID factor information and setting a superimposed waveform of read waveforms of these pieces of the ID factor information on the ID information. CONSTITUTION:Three tracks for recording information are set on a recording surface formed with magnetic substance all over the surface of a prepaid card. The 1st track is recorded with card information, and the 2nd track with distinctive cipher information featuring the ID information to be recorded on the next 3rd track. By utilizing the magnetic layer 14 consisting of two magnetic layers of upper layer 14a and a lower layer 14b, the 3rd track 13 is magnetically recorded with analog waveforms of the ID factor information in the layers 14a and 14b respectively, thus the superimposed waveform of these pieces of the information constituting the ID information. When the ID factor information in the upper layer 14a is rewritten, a phase difference is caused by this rewriting, so that a waveform of the sum is changed, and hence a phase difference between the information of layers 14a and 14b and an output level are changed at random. Consequently, high security can thus be obtained.

Title: Magnetic recording medium
Inventor: ISHIDA TOSHIO
IPC: G11B5/708
Filed: 1990-07-11
Abstract: PURPOSE:To obtain excellent durability and environmental adaptability by incorporating a specific thiourea deriv. into a magnetic layer. CONSTITUTION:The magnetic layer is provided on a nonmagnetic base and the thiourea deriv. expressed by formula I is incorporated or held in the magnetic layer. In the formula I, R1 denotes >=10 to <=26C hydrocarbon group; R2 to R4 denote the same or different hydrogen atom or >=1 to <=26C hydrocarbon group. As to the adsorption of this thiourea deriv. to ferromagnetic powder of a coating type medium, the competition with a fatty acid and the polar part of a binder arises and the thiourea deriv. is hardly adsorbed on the ferromagnetic powder. Since the thiourea deriv. is polarized in the molecule, the deriv. has a high inorg. property and the solubility in the binder is lower as compared with the fatty acid, etc. The always stable traveling durability is obtd. in this way even under severe conditions, such as high temp. and high humidity or low temp. and low humidity.
