US 7,609,483 B2 · Data storage device with load/unload tab inclined towards a disk

Abstract

Embodiments of the invention reduce the height of a ramp to provide a thin data storage device that is capable of inhibiting the deterioration of the dynamic characteristics at the time of loading/unloading. In one embodiment, a data storage device includes a head that accesses a recording region of a recording disk; a ramp that is positioned circumferentially apart from an outermost end of the recording disk to unload the head from a surface of the recording disk; and an actuator that includes a load beam for supporting the head and moves the head. The load beam includes a tab that is extended from a leading end section of the load beam, beyond the head support section of the load beam, and toward the recording disk, and slides over a ramp surface.

Dependent claims

A data storage device comprising:

a head which accesses a recording region of a recording medium;
a ramp which is positioned circumferentially apart from an outermost edge of the recording medium to unload the head from a surface of the recording medium;
and
an actuator which includes a load beam for supporting the head and moves the head;
wherein the load beam includes:
a head support section to support the head;
and
a tab which is extended forward, beyond the head support section, and toward the recording medium and which slides over a surface of the ramp,
wherein the head support section includes a flange, which is formed by bending both rims that are extended in a longitudinal direction,
wherein the flange is also formed on the tab, and
wherein the flange of the head support section and the flange of the tab merge forming a continuous flange.
