Mounting system for disk drive having a rotary actuator
View Patent ↗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.
1. A hard disk drive (HDD) capable of being supported in a frame and comprising:
a hard disk enclosure (HDE) comprising a baseplate, a spindle mo or mounted on the baseplate and supporting at least one disk, and a rotary actuator mounted n the baseplate and rotatable about an axis normal to the baseplate; and
a rotational bearing attached to the HDE baseplate an having its rotational axis coincident with the HDE pivot axis, the bearing permittin the HDE to pivot about an axis parallel to the axis of rotation of the rotary actuator when the bearing is secured to a support frame, the center of gravity of the HDE being located substantially on the HDE pivot axis.
2. A hard disk drive (HDD) capable of being supported in a frame and comprising:
a hard disk enclosure (HDE) comprising a baseplate, a spindle motor mounted on the baseplate and supporting at least one disk, and a rotary actuator mounted a the baseplate and rotatable about an axis normal to the baseplate;
a theta-mount attached to the HDE baseplate and permitting the HDE to pivot about an axis parallel to the axis of rotation of the rotary actuator when the theta-mount is secured to a support frame, the center of gravity of the HDE being located substantially on the HDE pivot axis; and
a restoring spring attached to the baseplate for returning the HDE to a neutral position when the theta-mount is secure to a support frame and the HDE has pivoted about its pivot axis.
3. The HDD of claim 2 , wherein the HDE further comprises an additional mass attached to the baseplate for locating the center of gravty substantially on the HDE pivot axis.
