Abstract
A rotary inertial latch is disclosed for maintaining the actuator of a disk drive in its proper position when the drive is not in operation.
Claims21
A disk drive for storing and/or retrieving information comprising:
- a disk comprising a storage medium and rotatable about an axis;
- means for rotating said disk;
- an actuator rotatable about a pivot and comprising a head for writing information on and/or reading information from said storage medium;
- and
- an inertial latch for preventing a rotational shock force acting on said disk drive from rotating said actuator with respect to said disk drive, said inertial latch comprising:
- an inertial body rotatable about an axis;
- engagement means joined to said inertial body, said engagement means being capable of engaging said actuator so as to prevent said actuator from rotating about said pivot point when said disk drive is subjected to a rotational shock force;
- and
- prevention means for preventing said engagement means from engaging said actuator when said disk drive is not being subjected to a rotational shock force.
