Method for calibrating write channel parameter on-the-fly and computer-readable recording medium thereof

摘要

on-the-fly to a method for correcting the write channel parameters and a program for executing the method recording medium is disclosed. The method includes the steps of performing a predetermined cycle read verification, the reading method comprising: monitoring the gain value of the read signal by the test, and on at least one parameter associated with the writing on the basis of the monitoring result of the gain-the - and a step of correcting a fly (on-the-fly). Periodically, the method performs a read verification, read by the verification result determining whether the writing is strong weak write or write, and corrects the write channel parameter to adjust the intensity of the writing. Write channel parameters on-the-fly by being corrected to have the effect of increasing the reliability of the data
