ABSTRACT:
A method and apparatus for data coding for high-density recording channels exhibiting low frequency contents is disclosed. Coding is used that satisfies both Running Digital Sum (RDS) and Maximum Transition Run (MTR) properties, which are desirable for achieving high-density recording for recording channels exhibiting low frequency components such as perpendicular magnetic recording channel.
