摘要： Thermal pole tip protrusion is caused by the materials in and around the head slider expanding during write operations till part of those materials protrude, leading to contact with the rotating disk surface, altering the flying height and often wearing down part of the disk surface. While it is well known that read-write heads expand during writing, the inventors are unaware of anyone else who recognized this situation's significance, particularly as the flying height decreases and the data rates increase, both of which are required for high areal density disk drives. The inventors realized that they could detect the problem at the spin stand level by testing head gimbal assemblies to reliably, and inexpensively, predict the tendency for thermal pole tip protrusion. This leads to selection of head gimbal assemblies, which do not have the thermal pole tip protrusion tendency. The selected head gimbal assemblies have better reliability, as do actuators and disk drives made with the selected head gimbal assemblies.
摘要翻译：热极尖突起是由写入操作期间头部滑块内和周围的材料引起的，直到这些材料的一部分突出，导致与旋转盘表面接触，改变飞行高度并经常磨损磁盘表面的一部分。虽然众所周知，读写头在写入期间扩展，但是发明人不知道任何认识到这种情况的人的意义，特别是当飞行高度降低并且数据速率增加时，两者都是高密度磁盘驱动器所需要的。本发明人意识到，它们可以通过测试头万向架组件可靠且廉价地预测热极尖端突起的趋势来检测旋转台水平的问题。这导致了不具有热极尖突起倾向的头万向节组件的选择。所选择的头万向架组件具有更好的可靠性，与使用所选择的头万向架组件制造的致动器和磁盘驱动器一样。

摘要： A method and apparatus for detecting a defective disk for a hard disk drive. The method includes placing a disk into a tester so that a first side of the disk is adjacent to a first head of the tester and a second side of the disk is adjacent to a second head. First data is read from the first side of the disk, and second data is read from the second side of the disk. The disk is then flipped so that the second side is adjacent to the first head and the first side is adjacent to the second head. Third data is read from the first side. Fourth data is read from the second side. A first area between a curve generated from the first data and a curve generated from the third data is calculated. Likewise, a second area is calculated between a curve generated from the second data and a curve generated from the fourth data. An average of the first and second areas is then calculated and used to detect a defective disk.

摘要： A disk drive that has a plurality of heads coupled to one or more disks. The heads have air bearing surfaces that compensate for a radial crown and a radial camber of an adjacent disk to maintain a flying height at a relatively constant level across the disk surface. By way of example, the air bearing surfaces may have crown and camber sensitivities that are opposite in sign from the crown and camber sensitivities created by the disk. The opposite sensitivities offset the sensitivities of the disk to maintain an essentially constant flying height as the head moves across the surface of a disk.

摘要： A method for dynamic in-situ characterization of in-plane and out-plane thermal drift of a hard disk drive head suspension is provided. A first data track is written. Amplitude and amplitude modulation of the write data signal are measured and track center is determined. Data tracks are then written for a selected time period. Amplitude and amplitude modulation of the write data signal is measured and a new track center of a last data track is determined. Any difference between the track center of the first data track and the track center of the last data track represents in-plane drift. The amplitude and amplitude modulation of the two write data signals is compared and any difference between the measured values is proportional to out-plane drift.

摘要： A dielectric mandrel structure is formed on a single crystalline semiconductor layer. An amorphous semiconductor material layer is deposited on the physically exposed surfaces of the single crystalline semiconductor layer and surfaces of the mandrel structure. Optionally, the amorphous semiconductor material layer can be implanted with at least one different semiconductor material. Solid phase epitaxy is performed on the amorphous semiconductor material layer employing the single crystalline semiconductor layer as a seed layer, thereby forming an epitaxial semiconductor material layer with uniform thickness. Remaining portions of the epitaxial semiconductor material layer are single crystalline semiconductor fins and thickness of these fins are sublithographic. After removal of the dielectric mandrel structure, the single crystalline semiconductor fins can be employed to form a semiconductor device.

摘要： An improved semiconductor capacitor and method of fabrication is disclosed. A MIM stack, comprising alternating first-type and second-type metal layers (each separated by dielectric) is formed in a deep cavity. The entire stack can be planarized, and then patterned to expose a first area, and selectively etched to recess all first metal layers within the first area. A second selective etch is performed to recess all second metal layers within a second area. The etched recesses can be backfilled with dielectric. Separate electrodes can be formed; a first electrode formed in said first area and contacting all of said second-type metal layers and none of said first-type metal layers, and a second electrode formed in said second area and contacting all of said first-type metal layers and none of said second-type metal layers.
