摘要： A nano imprint master and a method of manufacturing the same are provided. The method includes: implanting conductive metal ions into a substrate including quartz to form a conductive layer inside the quartz substrate; coating a resist on the quartz substrate in which the conductive layer is formed, to form a resist coating layer; exposing the resist coating layer to an electron beam to form micropatterns; etching the quartz substrate by using the resist coating layer, in which the micropatterns are formed, as a mask; and removing the resist coating layer to obtain a master in which micropatterns are formed.

摘要： A hard disk drive having a vibration reducing damper is disclosed. The hard disk drive is provided with a damper which is interposed between a through hole provided at a cover plate and a screw joined to the upper end of the shaft of a spindle motor, and includes at least one viscoelastic material layer. It is preferable that the damper has a multi-layered structure in which at least one high stiffness layer has relatively higher stiffness and at least one low stiffness layer made of a viscoelastic material has relatively lower stiffness. With the above configuration, the damper restrains vibrations generated by the spindle from being transferred to the cover plate, noises generated by the hard disk drive are reduced, and, in addition, since vibrations generated by the spindle motor are damped, disk fluttering is reduced.

摘要： A metallic wave guide and a light delivery module are provided. The metallic waveguide includes a metal body formed of a conductive metal and having an aperture formed therethrough, the aperture having input and output ends. The aperture has a bent portion for changing a light traveling direction between the input and output ends, and a tapered portion between the bent portion and the output end. The tapered portion has a width that is gradually reduced toward the output end, and the aperture is formed in a C-shape by a ridge formed on an inner surface of the metal body.
