Patent ID: 8093888

Claim:
A head assembly drive mechanism for moving a magnetic head in a direction crossing a track through a head assembly, which supports said magnetic head through a spring, comprising: a head holder for holding said head assembly including a first block, a second block and an actuator fixed to said first block or said second block, said head assembly being fixed to said first block and said first block and said second block being connected by a flexible coupling portion with a predetermined gap between them, said head assembly drive mechanism swinging said head assembly in such a way that said magnetic head moves in a direction crossing said track by bending said coupling portion by changing a size of said predetermined gap between said first block and said second block on either side of said coupling portion by said actuator, and a bent connecting portion disposed on an opposite side of said head assembly to said coupling portion, for connecting said first block and said second block together while allowing said first block to swing and to restore the size of said predetermined gap between said first block and said second block on either side of said coupling portion.
