Mounting system for disk drive having a rotary actuator

A disk drive assembly for mounting to a computer chassis, comprising:

• a hard disk enclosure (HDE) containing at least one disk and an actuator;
• and
• a drive frame including an inner frame for receiving the HDE and having at least one theta-mount provided on said inner frame, and an outer frame for mounting to said computer chassis.

A disk drive with a rotary actuator-based positioning mechanism, mounted so that it can rotate freely about an axis normal to the plane of actuator motion, comprising:

• a casing pivotably mounted to minimize at least one of settle-out dynamics, external rotational vibration, and emitted vibration, said casing allowing said HDE to rotate substantially freely,
• wherein said center of gravity of said HDE is substantially the same as a pivot point of said casing.

An apparatus for use with a mechanism that creates rotational torque, comprising:

• a casing pivotably mounted to minimize at least one of settle-out dynamics, external rotational vibration, and emitted vibration, said casing allowing said HDE to rotate substantially freely,
• wherein said center of gravity of said HDE is substantially the same as a pivot point of said casing.

A computer chassis, comprising:

• a housing;
• and
• a plurality of theta-mounts integrally built within said housing.
