Abstract
A recording medium is provided, such as paper, secured by magnetic microwires. The recording medium comprises: a pulp structure formed by pulp fibers, said pulp structure carrying microwires having a metal core of a predetermined material composition, and an insulating layer coating on said metal core; and at least one coating layer on at least one side of said pulp structure. The pulp structure is a single-layer structure with the microwires fully embedded in said single layer, the microwires having cross-sectional dimensions approximately equal to cross-sectional dimensions of the pulp fibers.
Claims17
A recording medium, comprising:
- a web structure formed by web fibers and carrying microwires having a metal core of a predetermined material composition comprising a soft-magnetic amorphous metal alloy capable of providing a response signal to an oscillating magnetic field, and an insulating layer coating on said metal core;
- at least one coating layer on at least one side of said web structure;
- wherein said web structure comprises a layer comprising the web fibers and the microwires which have the metal core of a cross-sectional dimension not exceeding 15 μm and length substantially not exceeding 10 mm and which are fully embedded in said layer being substantially uniformly distributed within a plane defined by said layer and arranged with a desirably high density that is higher than 1.0 per square centimeter in said layer for improving detectability of the response signals from the microwires when said recording medium is exposed to the oscillating magnetic field.
