Abstract
In this work, we derive the Thermal-WilliamsComstock model for the heat-assisted magnetic recording channels. The coercivity and remanent magnetization have linear relationship with the temperature. The transition width and transition centres can be obtained for various cases. Together with the microtrack model, the generation of transition response, dibit response as well as the readback of pseudorandom sequence with and without jitter noise can be achieved. © 2012 IEEE.
