HEAD SLIDER FOR HARD DISK DRIVE

摘要

PURPOSE: A head slider for a hard disk drive is provided to prevent a recording density of a hard disk from being declined by taking off a head slider from a magnetic disk rapidly when a hard disk drive is operated initially and by dropping a height of the hard disk when a hard disk drive is operated normally. CONSTITUTION: A plurality of rails(330, 350) having a predetermined height are mounted at the lower portion of a body(300). The rails(330, 350) are mounted to the body(300) by being corresponded thereto and generate variable takeoff power by an interactively bending operation caused by an applied voltage. The rails(330, 350) are a dimorph plate made by joining two piezoelectric elements(333 and 335, 353 and 355) in the reverse direction opposite to interactively.
