Automatic change of read factor for lead channel optimization

摘要

end. TECHNICAL FIELD The invention described in the claims pertains to a method of optimizing a read channel of a hard disk drive, and more particularly, to a method of automatically changing a read factor for automatically adjusting the priority of a read channel factor having a high frequency of error recovery in the event of a read error. It is about.;I. The technical problem to be solved by the invention: automatic change of the read factor that can recover the read error reliably and efficiently by automatically adjusting the priority of the read channel factor with high error recovery frequency in real time in case of data read error in the hard disk drive In providing a method.;All. Summary of the Invention Solution of the Invention: A method of automatically changing read factors for read channel optimization of a hard disk drive, wherein a read factor change function of a plurality of read factor change functions having a high error recovery frequency is preferentially sequenced when a data read error occurs. The method checks whether the data read error is recovered or not, and increases the frequency of error recovery of the corresponding read factor change function.;la. Important use of the invention: It can be used to optimize the read channel of a hard disk drive.
