摘要： An optical recording medium has a mask layer 4, an intermediate dielectric layer 5, a recording layer 6, and a reflective layer 8 on a transparent substrate 2. The recording layer 6 contains a recording material which changes its crystallographic structure upon exposure to recording light for recording information. The mask layer 4 contains a mask material which increases its light transmittance when melted and has a complex refractive index (n.sub.0 -ik.sub.0), of which the real part n.sub.0 drops by 1.0 or less and the imaginary part k.sub.0 drops by 0.25-1.0 when the mask material converts from a crystalline state to an amorphous or microcrystalline state. Signals can be reproduced from the medium with high C/N without resorting to reading light of shorter wavelength or an optical pickup objective lens having a larger numerical aperture and even when the linear velocity of the medium relative to recording and reproducing light is low.

摘要： An optical recording medium is prepared by forming on a substrate a phase change recording layer comprising elements A, B, C and optional D wherein A is silver and/or gold, B is antimony and/or bismuth, C is tellurium and/or selenium, D is indium or a mixture of indium and aluminum and/or phosphorus. Formation of the recording layer is carried out by the step of sputtering an A--C base metal and the step of sputtering a B base metal optionally containing D in this successive order or reverse order; or by the step of sputtering an A--C base metal, the step of sputtering a B base metal, and the step of sputtering a D base metal in this successive order or reverse order. Since the resulting recording layer is already crystallized, the method eliminates a need for extra initialization.

摘要： An optical information medium has on a substrate (2) with information-carrying pits (21), a light transmittance control layer (3) including a lower dielectric layer (31), a mask layer (32) and an upper dielectric layer (33). The mask layer has an original state before irradiation of reading light. Upon irradiation of a reading light beam to define a beam spot, the mask layer undergoes a crystal-to-crystal transition in a region (H) of the beam spot depending on the intensity distribution of the beam spot. Multiple reflection condition changes in the transition portion so that the beam spot contributing to read-out is limited to the transition or transition-free region (H or L). The transition temperature is in the range of 200.degree. to 450.degree. C. The mask layer returns to the original state after passage of the beam spot. The invention is also applicable to an optical recording medium having a recording layer above or below the transmittance control layer.

摘要： A current sensor includes first to fourth magneto-resistive elements each having a resistance value; and a compensation current line applying a compensation magnetic field to the magneto-resistive elements. A bridge circuit is formed by the magneto-resistive elements. Resistance values of the first and third magneto-resistive elements change together in one increasing/decreasing direction. Resistance values of the second and fourth magneto-resistive elements change together in the other increasing/decreasing direction. The compensation current is generated by a potential difference between the first and second junctions in response to application of voltage between the third and fourth junctions. The compensation current line includes first to fourth line portions. Each line portion extends in the same direction as the extending direction of the magneto-resistive elements, overlaps the corresponding magneto-resistive elements, and. The current-to-be-detected is detected based on the compensation current.
