Abstract: Disclosed is a magnetic latch for a disc drive. Upper and lower voice coil magnet pole pieces include extensions which bend toward one another, defining a gap therebetween. The gap creates a magnetic field which attracts and holds a disc drive actuator in a park position when the drive is not in use.

Abstract: A voice coil motor assembly in a disc drive includes first and second pole pieces held in spaced relationship to one another such that a gap is defined therebetween. A permanent magnet is located on the first pole piece within the gap and a dummy magnet is located on the second pole piece across the gap from the permanent magnet. The first and second pole pieces, together with the magnet and the dummy magnet, form a magnetic circuit conducting lines of magnetic flux within the voice coil motor and across the gap. The dummy magnet acts to encourage magnetic flux to flow across the gap in a manner such that the roll and pitch torque constants of the voice coil motor are reduced.

Abstract: A tenon and mortise are formed with a taper-dovetail shape. As the tenon is inserted into the mortise, because of the friction force between the contacting surfaces and the squeezing force of the taper, the tenon is fixed sturdily in the mortise and the tenon can be easily assembled or dismantled by a particular shaping of its outer surface.

Abstract: A method and apparatus for transmitting Channel State Information Reference Symbol (CSI-RS) and data with partial muting of the CSI-RS are proposed. The method includes determining a CSI-RS pattern to be used among CSI-RS pattern candidates, determining a muting pattern for muting some resource elements constituting CSI-RS pattern candidates except for the determined CSI-RS pattern, mapping data symbols and CSI-RS to resource elements in a resource grid with rate patching in consideration of the CSI-RS pattern and muting pattern, and transmitting the data symbols and CSI-RS to a terminal.
