Abstract :
In this work, we report a micromagnetic simulation study on narrow track recording characteristics in thin film media. It is found that, arising from interaction between track density and linear density, a sub-micron trackwidth imposes a limitation on linear density. In order to achieve a high track density greater than 75,000 tpi while keeping the required high linear density, eliminating the interaction between track and linear densities is needed, by either optimized medium design or head design
