Abstract :
Magnetic hysteresis and recording properties of network film media were studied via micromagnetic modeling. It was found that the chain-like arrangement of magnetic grains in the network media suppresses clustering magnetization reversal. In comparison with conventional thin film medium, the network medium exhibits lower transition noise at high recording densities. The network medium is also more thermally stable than the conventional film media with the same signal to noise ratio
