In the extended area, the disk damper provides a wall near the neighboring rotating disk surface that extends from the outside diameter to the inside diameter of the rotating disk surface. Experimental results have shown that this provides much more consistent dampening of disk vibrations and vibrations of a head stack assembly positioned anywhere from the inside diameter to the outside diameter. The hard disk drive including the disk damper. Using the disk damper in a hard disk drive to improve the reliability of the hard disk drive during track following. Making the hard disk drive using the disk damper, and the hard disk drive as a product of that manufacturing process.

摘要： The invention applies to servo controllers for at least the voice coil motor of a hard disk drive. Today, many control algorithms require 80 to 90 percent of the sampling period to complete their calculation of the next control, making computation time delay no longer negligible. The invention accommodates the transport delay, such as computation time delay, into the state estimator and into the whole control system. Experimental results using a commercial hard drive, as well as simulation results, show that the invention's method effectively improves the hard disk drive control system stability by increasing the phase margin and gain margin. The invention includes the method of operating the servo-controller, as well as the apparatus implementing that method. The invention also includes hard disk drives containing servo-controllers implementing the method, and program systems residing in accessibly coupled memory to a computer within the servo controller implementing the method.

摘要： Improved head gimbal assemblies reducing TMR (Track Mis-Registration) in a hard disk drive are provided. These head gimbal assemblies are as mechanically simple as contemporary head gimbal assemblies, support parallel flying sliders over flat disk surfaces, and reduce TMR' induced by disk vibration. They are easier to build, more reliable, and cost less to make, than other known approaches at comparable track densities and rotational rates. The improved head gimbal assemblies include three sets of mechanisms moving the slider parallel the disk surface, when the disk surface is flat, and radially moving the slider toward the track, when the disk surface is bent. The first and third mechanisms as well as the second and third mechanisms can be used together in a head gimbal assembly.An improved and distinctive servo-controller scheme resulting in an overall improvement in PES performance, particularly when applied to hard disk drives employing the invention's TMR reduction mechanisms. The servo-controllers trade off gain in the disk vibration frequency range, in favor of, increased rejection of low frequency disturbances. This leads to the lowest PES statistics, when applied to hard disk drives with the TMR reduction mechanisms of the invention.

摘要： A servo writer that writes servo information onto a disk of a hard disk drive. The servo writer can write servo information onto a disk of a hard disk drive while the disk is within an inner chamber of a housing. The rotating disk creates a flow of fluid within the inner chamber. The disk is rotated during the servo writing process. The density of a fluid medium within the inner chamber is controlled by a medium control system so that the density of the medium is less than the density of air at one atmosphere. Lowering the density decreases the amplitude of vibrational forces created by the flow of fluid. Decreasing the amplitude reduces errors in the servo writing process. The density can be reduced by pulling a vacuum within the inner chamber. The density can also be reduced by filling the inner chamber with a gas such as helium that has a lower density than air.
摘要翻译：将伺服信息写入硬盘驱动器的磁盘上的伺服写入器。伺服写入器可以在盘位于壳体的内腔内时将伺服信息写入硬盘驱动器的盘上。旋转盘在内腔内产生流体流。在伺服写入过程中，盘旋转。内室内的流体介质的密度由介质控制系统控制，使得介质的密度小于一个大气压下的空气密度。降低密度会降低由流体流产生的振动力的振幅。降低幅度会降低伺服写入过程中的误差。可以通过在内腔内拉真空来减小密度。通过用比空气密度低的诸如氦气的气体填充内室也可以减小密度。
