    Abstract: A method and an apparatus to detect data in a data storage device, and a method and an apparatus to effectively detect data in channels having characteristics in which bands of data to be reproduced are limited. The method includes partially selecting partial paths from paths of a Viterbi trellis having a number corresponding to an order of a polynomial used in equalization, in an order where path metric values increase from a path having a minimum path metric value, deciding a best path having a minimum path metric value among the partial paths, and detecting data based on the best path.

    Abstract translation: 一种检测数据存储装置中的数据的方法和装置,以及有效地检测具有特征的数据的方法和装置,其中要再现的数据频带受到限制。 该方法包括从路径度量值从具有最小路径度量值的路径增加的顺序,部分地从具有对应于均衡中使用的多项式的阶数的维度比特网格的路径中选择部分路径,从而确定具有 部分路径中的最小路径度量值,以及基于最佳路径检测数据。
