Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording medium which uses pigment in the lower side layer, which is markedly characterized in that it is every finely pulverized, more economical than the conventional pigment in the lower side layer and magnetically soft. SOLUTION: A multilayered magnetic recording medium, suitable for high recording density and digital recording, having superior electromagnetic recording characteristics and improved surface smoothness and capable of sufficiently absorbing a large quantity of lubricant in the lower side layer, is provided with an upper-side magnetic recording layer, having less than 0.5 μm layer thickness and at least one layer of lower side layer which includes the magnetically soft pigment.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording medium which has excellent electromagnetic characteristics in the entire range of the recording wavelength and excellent mechanical characteristics, is suitable for recording of digital data and can be manufactured by a well-known technique and in which the problem of head saturation is not caused. SOLUTION: In the multi layered magnetic recording medium suitable for high recording density and digital recording, having excellent electromagnetic recording characteristics in the entire range of a recording wavelength, excellent mechanical characteristics, improved surface smoothness and flat frequency response, an upper side magnetic recording layer having

Abstract: Tape-like magnetic recording media having a nonmagnetic substrate and at least one layer applied to the substrate having incorporated into at least one of these layers, an inorganic needle-shaped pigment which serves as a supporting pigment and has a ratio of the average length to the average diameter of the pigment of at least 3, and the mean modulus of elasticity of the layers is not less than 15 Gpa in the longitudinal direction of the tape-like recording media.

Abstract: PCT No. PCT/EP96/02677 Sec. 371 Date Dec. 17, 1997 Sec. 102(e) Date Dec. 17, 1997 PCT Filed Jun. 20, 1996 PCT Pub. No. WO97/03341 PCT Pub. Date Jan. 30, 1997An apparatus for irreversibly indicating that the permissible temperature of stored products has been temporarily exceeded is described, in which a container has a heat-conducting connection to the product to be monitored and contains, in its interior, a medium having a melting point which is just above the permissible storage temperature, magnetizable particles being suspended in the medium. Moreover, solid magnetizable bodies are uniformly distributed in the container. After the deep-freezing process is complete, the magnetizable particles and the solid bodies are magnetized. If the permissible storage temperature is exceeded, the suspension becomes liquid and the pigments accumulate on the solid bodies, an optical indicator present on a wall of the container and visible from the outside detecting that the permissible temperature has been exceeded.
