Abstract
A head holder includes a first and second blocks connected each other with a predetermined gap between the blocks by a flexible coupling portion. The second block supports the first block swingably by increasing a width of either one of spaces of the predetermined gap on opposite sides of the coupling portion and narrowing the other space by bending the coupling portion by a piezo actuator. A magnetic head is dynamically moved in a direction crossing a track by swinging a head assembly fixed to the first block.
