Abstract

Official abstract text for this publication.

An apparatus for detecting media flaws includes a branch metric selection circuit operable to select a first branch metric and a second branch metric, a subtraction circuit operable to subtract the second branch metric from the first branch metric to yield a difference, and a comparator operable to compare the difference with a threshold value and to indicate a presence of a potential flaw in a storage medium when the difference is less than the threshold value.

First claim

Opening claim text (preview).

What is claimed is: 1. An apparatus for detecting media flaws, comprising: a branch metric selection circuit operable to select as a first branch metric a branch metric value for a branch between a previous decision state and a subsequent non-decision state, and as a second branch metric a branch metric value for a branch between two successive decision states; a subtraction circuit operable to subtract the second branch metric from the first branch metric to yield a difference…
