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： A slim spindle motor and a micro-drive apparatus including the slim spindle motor are provided. In the spindle motor, a hub is rotatably mounted on a base plate by ball bearings. The hub is used to seat a disk thereon. A ring-shaped magnet is engaged to the outer boundary of the hub. A stator is formed by arranging a plurality of yokes in a round shape around the outer boundary of the ring-shaped magnet. The yokes include cores having curved ends to reduce the central axis offset between the yokes and the ring-shaped magnet. Most of the yokes include coils that cover the cores. Since the central axes of the yokes in the stator are made collinear with the central axis of the ring-shaped magnet, the slim spindle motor can operate stably.

摘要： A slim actuator and a micro-drive apparatus using the same are provided. The slim actuator includes a suspension having a head mounted at one end of the suspension to write/read data to/from a disk and a head gimbal assembly. The head gimbal assembly includes a unit-mounting portion having one end connected to the suspension, a fantail molding portion extending from the other end of the uni-mounting portion, and a voice coil which is mounted on the fantail mounting portion such that current flows in the voice coil. The voice coil rotates the suspension by an electromagnetic force created by interaction between the electric field of the current and an applied magnetic field. Thus, the slim actuator uses a single channel and has excellent resonance characteristics. Mobile micro-drive apparatuses employing the slim actuators can be obtained.

摘要： A linear actuator capable of inducing a linear motion as well as a rotational motion using only two rotors is provided. The linear actuator includes: first and second rotors connected to respective driving force sources; a linear motion unit formed on the first rotor to be linearly movable; and a driving power transmission unit which is fixed to the second rotor and engages the linear motion unit. A linear motion on a rotor can be easily induced using a relative angular velocity difference between two rotors without an additional driving power source for the linear motion.

摘要： Provided is a method of generating a magnetic field map including obtaining magnetic field information, the magnetic field information being information on a magnetic field affecting a mobile body, for each position of the mobile body, and building a magnetic field map based on the magnetic field information for each position of the mobile body. The pose of a mobile body can be statistically checked by the probability obtained using the difference between the magnetic field information observed from the magnetic field map and the actually measured magnetic field information. Although the pose of the mobile body is estimated using a camera that is sensitive to an illumination state where the mobile body is placed, the pose of the mobile body can be relatively accurately checked using the magnetic field map obtained in a situation regardless of illumination, with being less affected by the illumination state where the mobile body is placed. Thus, the pose of the mobile body can be checked with reliability.
