Abstract: A method of manufacturing an antenna includes forming a base including a synthetic resin, forming a conductive pattern on the base and forming a circuit pattern by sintering the conductive pattern by applying heat. The conductive pattern includes a conductive paste and a binding material binding the base and the conductive pattern. The conductive paste includes a metal.

Abstract: A signal transmitting device, for transmitting a signal between a head and a printed circuit substrate of a hard disk drive having functions of storing and reproducing data to/from a recording medium, least one head for reading or writing data from/to the recording medium, an actuator for positioning the head at a desirable track above the recording medium, a spindle motor for rotating the recording medium at a constant speed, and a pivot bearing provided with one or more slots which are provided with a electrically conductive oil and a plurality of pads connected to the electrically conductive oil.

Abstract: An actuator latching device in a hard disk drive maintains the actuator of the hard disk drive in a parking zone while the actuator is not in operation. The hard disk drive includes: a disk that rotates at a high speed via a spindle motor, an actuator rotatably installed upon a pivot to access the disk, head gimbals having a magnetic head installed at one end of the actuator, a bobbin installed on a bottom portion of the actuator, and a voice coil motor for driving the actuator. The actuator latching device of the hard disk drive includes: a latching member fixedly attached to the bobbin, and a latching unit fixed to a body base. The latching unit includes: a magnet for attaching to the latching member to maintain the actuator in the parking zone, and a solenoid coil for reducing the intensity of and reversing the direction of a magnetic field generated by the magnet.

Abstract: An apparatus for reducing impact upon a hard disk assembly in a hard disk drive includes: an upper frame, a lower frame, slots arcuately formed within corners of the upper frame and the lower frame, and elastic elements for buffering the hard disk assembly from impact. Each one of the elastic elements has a hole formed at a center portion and is inserted into the slots formed in the corners of the upper frame and the lower frame. Contact surfaces and arcuate recesses are provided at upper and lower portions of the corners of the hard disk assembly to accommodate installation of the elastic elements. A fastener attaches the elastic elements, the hard disk assembly, the upper frame and the lower frame together such that neither the upper frame nor the lower frame contacts the hard disk assembly.
