Title

STATISTICAL CHARACTERISTICS OF MAGNETIC RECORDING PARTICLES

Pages

  199-211

Abstract

 In MAGNETIC RECORDING MEDIA, the remnant magnetization loop, Mr (H) has some parameters, which explain the properties of the medium in view of the storage density and signal-to-noise ratio. It is necessary to find the mechanism of Mr variations from the statistical characteristics of the system. We have prepared samples of single-domain acicular iron particles with 0.3 µm length, and the oriented textures of particles formed. The EASY AXIS DISTRIBUTION of particles in the samples was determined using the results of magnetic measurements. The effect of the distribution width on Mrand coercively (Hc) have been studied. The deviation of results from the Stoner-Wohlforth model for Hc indicates a correlation in the medium due to the dipole-dipole interaction. We also present a technique for determining the SWITCHING FIELD DISTRIBUTION in medium, which has been used for various samples. A narrow distribution leads to narrow transition regions in the recording media, and an increase of signal. A high switching field at the maximum of distribution indicates the ability of high recording density.
