| Summary: | The present invention relates to the field of mass storage devices. More particularly, this invention relates to an apparatus and method for producing a stiffer of the E-block or actuator assembly in a disc drive.
A disc drive, includes a base, a disc stack rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly includes an E-block. The E-block for a disc drive includes a metal core and a ceramic coating on the metal core of the E-block. The ceramic coating on the metal core of the E-block is less dense than the metal core. The stiffness of the ceramic coating on the metal core of the E-block is greater than the stiffness of the metal core. In one embodiment, the E-block has a metal core of aluminum. The ceramic coating is may be formed using any method, including an electrochemical process or by depositing the ceramic coating onto the E-block. |
