Abstract

This paper presents the new practical method to obtain the Preisach density distribution. The particle coercive density distributions can be obtained from measured initial curve and major loop, and the particle interaction distributions are presumed to be Gaussian distribution based on previously obtained coercive densities in Preisach plane. The implemented values are agreed well with measured major and minor loops, and it is concluded that this method is easy to implement and gives better accuracy than conventional method. In the application of longitudinal high density recording systems, the magnitude of reading signal increases as the media coercivity increases and the media thickness decreases.
