Rapid Microtrack Modeling with Vibrations for Servo Perpendicular Recording in Hard Disk Drives

Microtrack model which simulates media noise in magnetic recording system, with vibration disturbances and noises from HDD, provides a realistic simulated environment for the study of perpendicular servo signal in ultra-high density (400Gbpsi) recording. The microtrack model works by slicing a full track into several microtracks. The transition position for each microtrack is randomly determined by the pdf derived from the magnetization profile.
