Abstract:

Magnetic recording systems have a widespread use in storing our data and information. As the amount of data to be stored is constantly growing and the size of consumer electronic devices is decreasing, it is necessary to enhance the performance of magnetic recording systems and increase their recording density. Since the performance and recording density is limited due to noise and ISI, we have to design better error correcting codes, pre-coders, equalizers and detectors to improve such systems.

In order to investigate the performance of the newly designed techniques and compare them with existing approaches, it is necessary to conduct large scale simulations. In this report, we discuss the details of a simulator to implement a magnetic recording system. In particular, we address different types of signaling methods, specially the EEPR4 signaling.
