摘要： A spindle motor assembly includes a spindle motor having a shaft and a hub that rotates on the shaft, and a hard disk having a data storage medium mounted in the form of a whole disk, and a fastener attached to the center of a bottom surface of the disk-shaped data storage medium that faces the spindle motor. The fastener is a screw or a nut. In the case in which the fastener is a screw, a head of the screw is attached to the bottom surface of the hard disk, and the body of the screw is received in a screw hole in the upper portion of the shaft of the spindle motor. In the case in which the fastener is a nut, the nut is engaged with an external thread on an outer circumferential surface of the hub of the spindle motor.

摘要： An actuator latch apparatus for a data storage device includes a latch lever installed on a base plate of the data storage device capable of pivoting and having a first latch portion provided at one end portion of the latch lever, a spring connected to the other end portion of the latch lever and made of a shape memory alloy to allow the latch lever to pivot in a predetermined direction by being deformed according to application of electric power, and a second latch portion provided at an end portion of an actuator moving a read/write head to a predetermined position of a disk. When the rotation of the disk is stopped and the actuator is parked at a parking position, the spring allows the latch lever to pivot in one direction so that the first latch portion interferes with the second latch portion, thus locking the actuator not to rotate, and when the disk rotates, the spring allows the latch lever to pivot in the opposite direction so that the first latch portion is separated from the second latch portion, thus allowing the actuator to rotate. Thus, a reliable operation of the actuator latch apparatus is available due to the characteristic of the shape memory alloy and the structure of the actuator latch apparatus is simplified.
摘要翻译：一种用于数据存储装置的致动器锁定装置，包括安装在数据存储装置的基板上的闩锁杆，其能够枢转并且具有设置在闩锁杆的一个端部处的第一闩锁部分，弹簧连接到另一端部并且由形状记忆合金制成，以通过根据电力的施加而使闩锁杆沿预定方向枢转;以及第二闩锁部分，其设置在致动器的端部，从而移动读/写前进到盘的预定位置。当盘的旋转停止并且致动器停在停车位置时，弹簧允许闩锁杆在一个方向上枢转，使得第一闩锁部分与第二闩锁部分相互干扰，从而锁定致动器不旋转，并且当盘旋转时，弹簧允许闩锁杆沿相反方向枢转，使得第一闩锁部分与第二闩锁部分分离，从而允许致动器旋转。因此，由于形状记忆合金的特性，致动器锁定装置的可靠操作是可用的，并且致动器闩锁装置的结构简化。

摘要： An actuator of a hard disk drive includes a swing arm having an axis or rotation, a suspension extending from a distal end of the swing arm, a read/write head mounted on the suspension, a coil support fixed to a proximate end of the swing arm so as to rotate with the swing arm and to which a voice coil motor coil is wound, a respective magnet disposed above and/or below the voice coil motor coil as facing the voice coil motor coil, and at least one magnetic retracting member of a magnetic material fixed to the coil support and attracted to the magnet. Each magnetic retracting member arrives close to the magnet when the swing arm is rotated clockwise or counterclockwise about its axis of rotation. Thus, the force of attraction between the magnetic retracting member and the magnet biases the wing arm in one of its directions of rotation such as that in which the swing arm is moved during an unloading operation in which the read/write head is parked.
