摘要： A disk fixing apparatus to fix a disk onto a spindle motor in a hard disk drive (HDD). The apparatus includes a coupling hole, in which a coupling portion to fix the disk fixing apparatus onto the spindle motor is inserted, on a center portion of the disk fixing apparatus, and an attaching portion, to which the disk is attached on an outer portion of the disk fixing apparatus. The attaching portion includes an attaching surface extending in a vertical direction so that a part of an inner circumferential surface of the disk can be attached to the attaching surface and/or an attaching surface facing an upper surface or a lower surface of the disk and extending in a horizontal direction so that a part of a non-recording region on the upper surface or the lower surface of the disk can be attached to the attaching surface. Thus, the stress applied to the disk can be reduced and the deformation of the disk can be reduced, and thus, changes in floating height of the head slider can be minimized. Therefore, the recording and reproducing performances of the magnetic head can be improved, and the recording density of the disk can increase.

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： A hard disk drive (HDD) includes a spindle motor, an actuator, a static eccentricity sensor, a monitor and a central controller. The spindle motor includes a rotary body and a static body adapted to support the rotary body, where the spindle motor is adapted to rotate a disk. The actuator is adapted to move a read/write head over the disk. The static eccentricity sensor is adapted to measure static eccentricity associated with the rotary body. The monitor is adapted to monitor the measured static eccentricity and generate a free-fall signal when the monitor determines that the HDD is in a free-fall state. The central controller is adapted to initiate an unloading/parking operation for the read/write head in response to the free-fall signal.
