Abstract:
An actuator locking mechanism for use with an information storage device which locks an actuator to a base to avoid being moved with impact force, the mechanism comprising:said actuator on which a transducer for transferring information between the transducer and a storage medium is mounted and which is driven to scan the storage medium;a support member pivotally attached to the base at a pivot point, said support member comprising a first and a second arm extending from said pivot in opposite directions;an attracting member mounted on the first arm of the support member, which is attractable with at least a portion of said actuator at a stop position of said actuator; anda u-shaped elastic member attached at the pivot point of the support member and having two arms extending outward therefrom towards an end of the second arm of the support member, said elastic member having a range of motion defined by the contact between the outer side of the arms of the u-shaped elastic member and a hole at the end of the second arm of said support member and a fixing pin extending therethrough;wherein said elastic member is elastically deformed to give elastic force to said actuator by impact force given to the information storage device during the time the portion of said actuator is attracted to said attracting member, whereby said elastic member absorbs the impact force.
