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： The invention includes a yoke assembly containing a top and a bottom proximity latch magnet. The invention includes a voice coil attached to a voice coil bias steel. The crash stop includes a magnetic proximity latch created by the voice coil bias steel attracted to the top and bottom proximity latch magnets. It may also include using the magnetic proximity latch with a magnetically weakened contact latch. Experiments have shown that the combined magnetic proximity latch and the magnetically weakened contact latch require significantly less initial releasing force than the prior art crash stops, and meet rotary shock requirements. The invention includes making the actuator assembly, the voice coil motor assembly, and the CSS hard disk drive. The invention includes operating the CSS hard disk drive with at least the magnetic proximity latch.
