MANUFACTURE OF AIR LOCK ACTUATOR LATCH ASSEMBLY AND DISK DRIVE AND METHOD FOR RESISTING ROTARY IMPACT FORCE IN HARD DISK DRIVE

摘要

PROBLEM TO BE SOLVED: To provide the air lock latch assembly for suppressing a disk drive actuator at the time of receiving rotary impact force by the disk drive under the state of nonspin of the disk. ;SOLUTION: The latch assembly 20 comprises a latch member 21 capable of engaging with an anti-inertia member 28 by meshing their respective gears on the members with each other. The latch member 21 and the anti-inertia member 28 are featured by their respective moment of inertia, and their ratio is decided by a gear ratio of their teeth. Moreover, when linear impact force is received by the disk drive, the actuator is suppressed in its appropriate position by the latch assembly.;COPYRIGHT: (C)1998,JPO
