Patent ID: 7085107

Claim:
A disk drive, comprising: a disk-shaped storage medium supported for rotation; a head slider holding a read/write head for reading recorded data from the disk-shaped storage medium and writing data to the disk-shaped storage medium; a moving member supporting the head slider and placing the head slider at a read/write position on the disk-shaped storage medium, and retracting the head slider from the read/write position on the disk-shaped storage medium, the moving member having a pair of coil holding arms with a voice coil mounted therebetween, and a shape that extends from only one of said pair of coil holding arms; only one latching mechanism capable for latching the moving member in place when the head slider is retracted from a read/write position on the disk-shaped storage medium to a home position, and remaining separate from the moving member when the head slider is located at the read/write position on the disk-shaped storage medium; a ramp for holding the retracted head slider, wherein the only one latching mechanism latches the moving member in a state where the head slider is held by the ramp, and the latching mechanism being unable to latch the moving member when the head is located at the read/write position; and wherein the only one latching mechanism is an inertial latching mechanism that operates in response to an external shock, the moving member having a shape that contacts the latching mechanism and the shape is narrow and elongate and has a recess formed therein.
