摘要： A MEMS device package and a method of manufacturing the same. The MEMS device package includes a device substrate having a surface on which a MEMS active device is formed, and multiple sealing pads arranged around the MEMS active device so that the sealing pads provide electric paths for the MEMS active device. In addition, the MEMS device package may include a cap substrate bonded to the device substrate through the multiple sealing pads, the cap substrate including a trench, within which the MEMS active device is positioned, and via holes. One or more outer electrode pads may be formed on one surface of the cap substrate to be electrically connected with the multiple sealing pads through the via holes. Because there are several bonding and sealing areas between the device substrate and the cap substrate, the sealing intensity is strengthened.

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： In an actuator latch used with a hard disk drive to lock an actuator in a non-pivoting position when a magnetic head installed at the actuator is positioned in a parking zone of a hard disk, the actuator latch includes a hooked portion provided at one side of the actuator and having first and second hook steps disposed to face each other, a locking member having a hook portion which is coupled to the hooked portion as the actuator moves to the parking zone, the hook portion coupled to the hooked portion being interfered with the first hook step when the actuator rotate clockwise and with the second hook step when the actuator rotate counterclockwise, and an elastic member elastically supporting the locking member to be capable of rotating and providing a restoring force to the locking member with respect to both clockwise and counterclockwise rotations of the locking member. Thus, when a clockwise or counterclockwise rotational impact is applied to the hard disk drive, the actuator latch restricts rotation of the actuator so that the actuator cannot escape from the parking zone and the hard disk drive can be protected from being damaged.

摘要： A data storage device using magnetic domain wall motion may include a first magnetic layer having a plurality of magnetic domains. A second magnetic layer may be connected to the first magnetic layer, and a connection layer may be disposed between the first and second magnetic layers. A resistive magnetic layer may be disposed between each of the first and second magnetic layers and the connection layer. Accordingly, when current is supplied to the data storage device to move a magnetic domain wall, the leakage of current in a connection between the magnetic layers may be reduced or prevented, thus conserving power.
