Abstract: A technique for preventing damage to ball bearings in small form factor device is disclosed where the device has at least one crash stop ring disposed about the shaft and inside the rotor of a device. The ring is dimensioned to permit only a small amount of movement of the rotor relative to the shaft. The permitted movement is less than the minimum movement which would cause damage to the elements of the ball bearing.

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.
