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： The invention includes a testing method which may be applied to at least one writer in a disk drive during the self-test phase to generate write parameters, focused on the Over Shoot Control (OSC) of the write current parameter to improve the reliability of write operations by that writer. The Minimum OSC is used for write operations in normal temperatures. The Optimum OSC is used for a first lower temperature range, preferably between essentially 15 degrees Centigrade and essentially 5 degrees Centigrade. The Maximum OSC is preferred below essentially 5 degrees Centigrade. The Minimum OSC should preferably guarantee both an Adjacent Track Write (ATW) criteria, as well as guarantee a Write Induced Instability (WII) criteria. The invention includes the write parameter collection, as well as the disk drive containing the generated write parameter collection. The invention also includes the method of using that write parameter collection to control a writer while writing to tracks belonging to the radial zone collection and program systems implementing the invention's methods.

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 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 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： An LCD device has scratch-resistant property without using a protection sheet and can provide enhanced brightness. The LCD device includes a light path regulating member. The member includes a first prism sheet having first prisms of which apex has a round shape. The first prism sheet concentrates light supplied from a lamp to output the concentrated light. An anti-glare polarizing plate uniformly polarizes polarized planes of the concentrated light and provides the polarized light to the lower substrate. The anti-glare polarizing plate is arranged below the lower substrate of an LCD panel, and an uppermost prism sheet of optical sheets is non-matte-treated and has round-treated apexes. In spite of the absence of the protection sheet, the scratch-resistant property of the uppermost prism sheet and the brightness of the LCD panel may be enhanced.
