Recording disk drive

A disk drive comprising:

• a head actuator member supporting a head slider, said head actuator member following a predetermined path when released from a ramp member based on swinging movement around a support shaft;
• a lever supported on a first shaft for swinging movement, said lever defining first and second operating spots distanced from the first shaft by first and second distances, respectively;
• a weight supported on the first shaft for connection to the lever, said weight distanced from the first shaft by a third distance shorter than the first and second distances;
• and
• a swinging member supported on a second shaft for swinging movement, said swinging member located at a position defined between the first and second operating spots within a space between the lever and a cover, wherein
• said swinging member comprises:
• a first swinging piece designed to contact the first operating spot of the lever swinging in a first direction so that the first swinging piece swings around the second shaft into the predetermined path of the head actuator member;
• and
• a second swinging piece designed to contact the second operating spot of the lever swinging in a second direction opposite to the first direction so that the second swinging piece allows the first swinging piece to swing around the second shaft into the predetermined path of the head actuator member.
