WRITE CONTROLLING METHOD, A DISK DRIVE APPLYING THE SAME, AND STORING MEDIUM FOR PERFORMING A WRITING OPERATION BY OPTIMIZING A HEAD LEVITATION HEIGHT IN CONSIDERATION OF THE EXPANSION PROPERTY OF A HEAD

摘要

PURPOSE: A write controlling method, a disk drive applying the same, and storing medium for performing a writing operation are provided to prevent degradation of write quality by determining a parameter value for preheating.;CONSTITUTION: A processor determines a parameter value for controlling the FH(Flying Height) before write operation start(S301). The processor applies an optimal preheating parameter value about a zone including a track before writing operation with the control of a disk drive(S302). The processor performs a write operation after control of head FH(S303).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S301) Determining a parameter value for controlling FH before starting writing operation; (S302) Controlling FH before starting writing operation by applying a determined parameter value; (S303) Executing writing operation after controlling FH before starting writing operation
