摘要： A disk drive includes an enclosure having a base, a spindle motor fixed to the base, a disk mounted on the spindle motor, a pivot bearing cartridge, and a head stack assembly. The pivot bearing cartridge includes a shaft fixed to the enclosure, and the head stack assembly is connected to the pivot bearing cartridge for rotation relative to the shaft. The head stack assembly includes a body portion having a bore which surrounds the pivot bearing cartridge, a plurality of actuator arms with each arm cantilevered from the body portion, and a coil portion. The coil portion is cantilevered from the body portion in an opposite direction from the plurality of arms and provides damping of vibrations induced in the head stack assembly. The coil portion includes a plastic portion having a thickness, and a coil embedded in the plastic portion. The plastic portion includes a plurality of openings where each opening extends through the entire thickness of the plastic portion. Each opening is also located inside the coil and is substantially elongated in the direction in which the coil portion is cantilevered.

摘要： An actuator coil for a disk drive is formed of materials and processed in a manner such that the amount of outgassing that occurs in normal operation of the disk drive is minimized. An insulative coating, such as polyurethane which is rated well above the normal operating temperature is first applied to drawn copper wire. Then, a polyamide bond coating was used to cover the insulative coating. Next, a lubricant having a low average molecular weight was selected. The resulting wire was then wound to form the actuator coil. The coil is then cured at a high temperature for an extended length of time to drive off solvents and allow the polymers to crosslink and stabilize.

摘要： A solid state data storage assembly includes thermal interface material that conducts heat away from electrical components of the assembly. In some examples, the thermal interface material is positioned between a printed circuit board assembly, which includes electrical components, and a cover of a housing of the data storage assembly. The thermal interface material may also provide shock protection for the data storage assembly by at least one of increasing a stiffness of the data storage assembly, absorbing some mechanical loads applied to the data storage assembly or distributing the applied loads. In addition, in some examples, the thermal interface material exhibits some tackiness, such that removal of a thermal interface material from a data storage assembly and subsequent repositioning of the thermal interface material within the data storage assembly may provide a visual indication of tampering.

摘要： A monostable active latch apparatus is disclosed for use in a hard disk drive which has a housing, a rotating data storage disk and an actuator mounted in the housing. The actuator controllably positions a read/write head over a predetermined portion of the disk and includes a voice coil motor coil carried by a yoke portion of the actuator. The active latch uses a permanent magnet to bias an elongated rotatable latch arm into engagement with the actuator when the actuator is positioned in the landing zone. An electromagnet coil, positioned between the magnet and the magnetic return plates, when energized, counters this bias, permitting the latch arm to rotate, counterclockwise, out of engagement with the actuator. When the coil is deenergized, the permanent magnet provides a clockwise torque on the arm, raising the latch end of the latch arm to a first position out of the path of the actuator. When the coil is energized, the latch end of the latch arm is driven to a second position beneath the rear end of the actuator. If the coil is deenergized while the actuator is positioned in the landing zone of the disk, the latch end of the latch arm catches and latches the actuator, preventing further rotation of the actuator until the coil is again energized and the actuator moved away from the landing zone.
摘要翻译：公开了一种用于硬盘驱动器的单稳态主动锁定装置，其具有外壳，旋转数据存储盘和安装在壳体中的致动器。执行器可控制地将读/写头定位在盘的预定部分上，并且包括由致动器的轭部支承的音圈电机线圈。当致动器定位在着陆区域中时，主动闩锁使用永磁体来将细长的可旋转锁臂偏置成与致动器接合。位于磁体和磁性返回板之间的电磁线圈通电时，反映了该偏压，允许锁定臂逆时针旋转，使其与致动器不接合。当线圈断电时，永磁体在臂上提供顺时针转矩，将闩锁臂的闩锁端提升到致动器路径外的第一位置。当线圈通电时，闩锁臂的闩锁端被驱动到致动器后端下方的第二位置。如果线圈在致动器位于盘的着陆区域时被断电，则闩锁臂的闩锁端卡住并锁定致动器，防止致动器的进一步旋转，直到线圈再次通电，并且致动器远离着陆区。

摘要： A hard disk drive that contains a detection circuit which senses the back emf of a voice coil. The detection circuit generates a shock detection signal when the back emf of the voice coil exceeds a pre-determined value.
