Abstract: A head stack assembly of a hard disk drive includes a swing arm having a prong at its leading end, an actuator for rotating the swing arm, and a head gimbal having a head slider including a read/write head for reading/writing data from/onto a disk. The head gimbal is supported by the swing arm such that the head slider protrudes from the prong of the swing arm. The swing arm is configured to prevent the head gimbal from being vibrated due to windage. In particular, the swing arm defines a slot in one side of the prong, and a flexure of the head gimbal is received in the slot.

Consequently, the connection member according to the present invention has the effect of effectively interconnecting the electrode terminals of the battery cells through a simple assembly process.

Abstract: Disclosed herein are a method of coupling a conductive member for electric connection ('connection member) to a desired device by welding, wherein the connection member includes a corrosion prevention coating layer formed on a plate body of a high electrical conductivity and an embossed structure formed at one end thereof, and wherein the method comprises locating the connection member such that a protrusion of the embossed structure is brought into contact with a predetermined region of the device, at which the connection member will be connected to the device, making a welding rod come into contact with a depression opposite to the protrusion, and performing resistance welding, and a conductive connection member coupled by the coupling method. The coupling method has the effect of substituting for nickel, which has low price competitiveness, and solving the problems caused during the welding process, thereby greatly improving the productivity and greatly reducing a possibility of defect.

Abstract: In one embodiment, the method includes modifying data being copied such that portions of the data that include defects are replaced with dummy data. For example, a defective portion of the data is detected during a copy operation, and the data being copied is modified such that detected defective portions of the data are replaced with the dummy data.

Abstract: A method of forming a metal wiring for a semiconductor device includes forming a metal-based layer on a substrate, the substrate including at least one conductive structure, forming a metal seed layer on the metal-based layer, forming a supplementary contact layer on the metal seed layer along peripheral portions of the substrate, the metal seed layer being between the substrate and the supplementary contact layer, and the supplementary contact layer including a supplementary metal having an electrical resistance smaller than or equal to an electrical resistance of the metal seed layer, loading the substrate into a plating apparatus, such that the supplementary contact layer is being in direct contact with the cathode of the plating apparatus, and performing an electroplating process on the metal seed layer to form a metal wiring layer on the metal-based layer.

Abstract: A method of removing an insulation layer pattern covering metal wires includes providing an insulation layer pattern on a substrate, the insulation layer pattern having openings exposing the substrate, forming metal wires in the openings by depositing a barrier layer on inner surfaces of the openings, such that a lower portion of the barrier layer is thinner that an upper portion of the barrier layer, and depositing a metal layer to fill the openings, and performing an etching process with an etching vapor to remove the insulation layer pattern from the substrate to expose the metal wires.

Abstract: A hard disk drive having a housing with a base and a cover connected to each other, a spindle motor connected to the base, a disk mounted on the spindle motor and rotating with respect to the base, and an actuator rotatably connected to the base and supporting a slider with a magnetic head mounted on a front end thereof. The magnetic head writes and/or reads data to and/or from the disk. The hard disk drive also has a blade protruding from a surface of the base and/or a portion of the cover facing the disk. The blade guides an air flow caused by rotation of the disk toward an outer edge of the disk.

Abstract: A head stack assembly (HSA) mounting structure and a hard disk drive (HDD) including the assembly includes a base member including a shaft protruding upwards and a shaft circumference groove formed around the shaft. An HSA is rotatably placed on the shaft through a pivot bearing including an inner case contacting the shaft, and including a lower end portion received in the shaft circumference groove. A cover member may be coupled to the base member and a fixing screw may pass through the cover member to be threadedly coupled to the shaft.

Abstract: There is provided a cleaning solution spraying unit. The cleaning solution spraying unit comprises a number of nozzles installed in a nozzle base, along a top surface of a wafer, and radially spraying a cleaning solution on the wafer, wherein the nozzle base is positioned above the wafer; and a power unit rotating the nozzles at a predetermined angle relative to a line extending perpendicularly from the top surface of the wafer. In addition, provided is a wafer cleaning apparatus including the cleaning solution spraying unit with the above-described constitution.
