ABSTRACT:
The invention provides a method insuring that each read channel optimization step is controllable in terms of quality divergence, that a systematic response can be made which can be readily automated. The method is applicable to a pre-existing read channel optimization (RCO) script. The method includes the following operations. Acquiring a first quality measure and a first parameter list. Performing the pre-existing RCO script creating a second quality measure and a second parameter list based upon the first parameter list. Convergence processing the first and second quality measures and parameter lists.
