Abstract
Non-linear distortion in the form bf partial erasure is a primary impe diment at high magnetic recording densities. This paper simplifies a d ecision-feedback tree-search receiver for combating partial erasure. U tilizing an internal flag and a pre-computed threshold lookup table, t he proposed receiver requires no multiplications for its metric comput ation.
