Abstract :
The mechanism of particle interaction in particulate magnetic recording media has been investigated using a simple model for the particle switching process. The model allowed simulation of about 1000 interacting particles. It was found that the exact definition of the particle collective is decisive. Furthermore, the average interaction field appears to consist of two independent parts, one related to the well-known demagnetizing field and the other which only depends on the structure of the particle arrangement.
