METHOD FOR OPTIMALLY SETTING A MAGNETIC HEAD LIFTING HEIGHT OF A HARD DISC DRIVE CAPABLE OF INCREASING RECORDING CAPACITANCE AND A HARD DISC DRIVE MANUFACTURED BY THE SAME

摘要

PURPOSE: A method for setting the optimal lifting height of a magnetic head of a hard disc drive and a hard disc drive manufactured by the same are provided to set an optimized height for lifting a magnetic head based on a set table value and an MRR(Magnetic Resistor Resistance) value of the magnetic head during a hard disc drive manufacturing process.;CONSTITUTION: A controller measures a parameter value for the lifting height of a magnetic head and a recording capacitance value of a hard disc drive corresponding to the parameter value. The controller manufactures a table based on the measured values(S100). The controller optimizes the lifting height of the magnetic head by comparing a parameter value measured during a hard disc drive manufacturing process with the table(S200).;COPYRIGHT KIPO 2012
