Abstract :
A self-consistent micromagnetic recording model is utilized to study the effects of write head field rise time in tape recording. It is found that fast speed and slow field rise time result in degradation of recording performance for both nonequalized and write equalized cases. It also suggests that D=T/2 scheme could be more suitable than the D=T/3 scheme in write equalization at high speeds
