Abstract: A system for mounting a hard disk enclosure (HDE), includes a casing pivotably mounted to minimize at least one of settle-out dynamics, external rotational vibration, and emitted vibration, the casing allowing the HDE to rotate substantially freely, wherein the center of gravity of the HDE is substantially the same as a pivot point of the casing. Further, a computer chassis includes a housing, at least one disk drive assembly for being housed by the housing, and a plurality of theta-mounts integrally built within the housing.

Abstract: A system for mounting a head/disk assembly (HDA), of the type including at least one information storage disk, a spindle on which said disk is rotatabl y mounted and a rotary actuator for positioning at least one head relative to the disk comprises a support structure and means (87, 83) for mounting the H DA on the support structure to permit a limited amount of substantially free rotation in reaction to movement of the actuator thereby to reduce vibration in the HDA. The HDA may be part of a hard disk enclosure (HDE) or an entire hard disk drive (HDD) mounted in a computer chassis.

Abstract: In a direct access storage device including a rotating disk, a head positioned for interaction with said disk, an actuator for carrying said head and a servo system for operating said actuator so as to follow a substantially circular track on said disk by responding to a position error signal, a method for reducing response of the servo system to radial runout of the circular tracks, comprising the steps of obtaining radial runout data; filtering the data; storing the filtered data; subtracting the filtered data from the position error signal to obtain a corrected position error signal; and using the corrected position error signal to control the servo system. A direct access storage device in accordance with the invention includes means for obtaining radial runout data; means for filtering the data; means for storing the filtered data; means for subtracting the filtered data from the position error signal to obtain a corrected position error signal; and means for controlling the servo system using the corrected position error signal.
