METHOD FOR DETERMINING POSITIONING LIMIT VALUE AND DISK STORAGE DEVICE UTILIZING THE POSITIONING LIMIT VALUE DETERMINED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To reduce the effect of a head onto an adjacent track without the need for the head to trace an extreme narrow track width even under high track density while reducing the frequency of a head waiting for data recording.;SOLUTION: The method includes: a step S38 of measuring a fringe amount (Delta-BER) of the head to determine a positioning limit value at data recording with the head on the basis of the measurement resu a step S40 of creating a table on which determined positioning limit values are registered; and a step S45 of storing the table so as to be usable in a control state of positioning the head to a target track for recording of data onto the target track.;COPYRIGHT: (C)2004,JPO
