Abstract: A magnetic head parking system of a hard disk drive to move a magnetic head mounted on a slider of an actuator from a data zone of a disk and to place the magnetic head in a parking zone thereof when the disk stops rotating. The magnetic head parking system includes a head limiter provided on an upper surface of a flange of a spindle motor to protrude toward the disk and restricting a range of movement in upward and downward directions of the magnetic head placed in the parking zone of the disk. The head limiter is provided at a position opposite to a position where the slider of the actuator is installed or at a position deviating from and/or adjacent to a position directly under the slider. Thus, when an external impact is applied and an operation of the hard disk drive is stopped, the range of the up and down movement of the magnetic head is limited by the head limiter, so that the possibility of the damage to the magnetic head due to the head slap can be lowered.

Abstract: A hard disk drive that includes a wave stringer. The wave stringer can attenuate energy which propagates through a base plate of the disk drive. The wave stringer may be designed by initially analyzing propagation patterns of both acoustic and shock waves applied to the drive. The wave stringer is then designed, constructed and assembled to the disk drive to attenuate critical frequencies at weak points of the disk drive. The wave stringer may have a plurality of ribs designed to vary the mechanical impedance of the drive to attenuate the propagated energy.

Abstract: PURPOSE: A transfer backup device of an electrophotographic printer is provided to reduce a pressurizing power and secure the uniformity of pressure between a photoconductive belt and a first transfer roller. CONSTITUTION: A photoconductive belt(111) has an image forming surface. A transfer unit(120) transfers toner images formed on the image forming surface to a sheet of recording paper(126). A transfer backup device(110) backs up the transfer unit and the photoconductive belt when the toner images are transferred from the photoconductive belt to the transfer unit. A conductive sponge(132) of the transfer backup device is arranged to compress the photoconductive belt to the transfer unit to form a low pressure and a high nip between the photoconductive belt and the transfer unit. First and second auxiliary rollers guide the photoconductive belt towards the conductive sponge to help the formation of the low pressure and the high nip.
