摘要： A magnetic recording disk drive has three vibration sensors mounted to the disk drive base to provide feedforward vibration compensation signals. First and second spaced-apart sensors are aligned generally parallel to a radius from the disk rotational axis to a head position on the disk between the inside diameter position (hID) and outside diameter position (hOD) for detecting rotational vibration about the disk rotational axis and linear vibration in the cross-track direction. A third vibration sensor is aligned generally orthogonal to the primary axes of the first and second vibration sensors for detecting primarily linear vibrations in the along-the-track or track circumferential direction. The disk drive servo control processor calculates, from the signals from the three sensors, a rotational vibration feedforward signal, a radial linear vibration feedforward signal, and a circumferential linear vibration feedforward signal which are summed with the actuator control signal to compensate for the vibrations.

摘要： A thermally-assisted recording (TAR) disk drive uses “shingled” recording and a rectangular waveguide as a “wide-area” heat source. The waveguide generates a generally elliptically-shaped optical spot that heats an area of the recording layer extending across multiple data tracks. The waveguide core has an aspect ratio (cross-track width to along-the track thickness) that achieves the desired size of the heated area while locating the peak optical intensity close to the trailing edge of the write pole tip where writing occurs. The large cross-track width of the waveguide core increases the volume of recording layer heated by the optical spot, which reduces the rate of cooling. This moves the peak temperature point of the heated area closer to the write pole tip and reduces the temperature drop between the peak temperature and the temperature at the trailing edge of the write pole tip where writing occurs.

摘要翻译： 热辅助记录（TAR）磁盘驱动器使用带状闪烁的记录和矩形波导作为广域热源。 波导产生大致椭圆形的光点，其加热跨越多个数据轨道的记录层的区域。 波导芯具有实现加热区域的期望尺寸的纵横比（沿轨道厚度的横越轨道宽度），同时将峰值光强度定位在写入发生时写入磁极尖端的后缘附近。 波导芯的大的横向轨道宽度增加了由光点加热的记录层的体积，这降低了冷却速度。 这使得加热区域的峰值温度点更接近写极端，并且降低峰值温度与写入磁极尖端的后缘处的温度之间的温度下降。

摘要： Approaches for a hard-disk drive (HDD) baseplate comprising a recessed region that provides additional clearance for a disk. The protective enclosure of the HDD comprises a baseplate. The surface of the baseplate, which opposes a magnetic-recording disk, comprises a recessed region near the outer diameter (OD) of the magnetic-recording disk. The recessed region prevents the disk from being damaged through inadvertent physical contact with the baseplate, which may arise when the HDD receives a mechanical shock. The recessed region may be designed to minimize the damage to the disk if physical contact between the disk and the baseplate does occur. The recessed region may have a variety of shapes, such as a circular indentation or one or more non-contiguous regions in the baseplate where physical contact between the disk and the baseplate is deemed likely to occur.

摘要： A pure rotary microactuator comprising a spring assembly etched within a silicon substrate is disclosed. A first piezoelectric device is coupled with a first portion of the spring assembly and a second piezoelectric device coupled with a second portion of the spring assembly. The first piezoelectric device changes shape in response to an electrical input signal, and this change in shape provides a first push force to the first portion of the spring assembly in a first direction. The second piezoelectric device also changes shape in response to the electrical input signal, and this change in shape provides a second push force to the second portion in a second direction, which is different from the first direction. The combination of the first and the second push forces rotates the spring assembly with respect to the silicon substrate.
