Magnetic storage medium containing at least two different populations of magnetic particles each population having a separate mean coercive field strength

A magnetic storage medium for the storing of analog signals possessing magnetic particles having a coercive field strength distributed around a means value (H.sub.c), characterized in that

• said magnetic storage medium having at least two different populations of magnetic particles, each population consisting of magnetic particles which are essentially homogeneous in shape or in a physical or chemical property;
• each population of magnetic particles has a respective coercive field strength distributed around a respective means value (H.sub.c10, H.sub.c11) which results from the chemical and physical properties of the magnetic particles;
• each means value (H.sub.c) of the coercive field strength of a respective population of magnetic particles is different from the mean value of the coercive field strength of the other respective population of magnetic particles;
• and
• said magnetic particles are arranged in several layers, and for at least onbe layer of the several layers the statistical distribution of coercive field strengths, as compared to a Gaussian distribution, is broadened in the range of the most frequent coercive field strength value.
