Abstract: An electronic device includes a main body having a top wall, a bottom wall and a front sidewall, and a hard disk drive received in the main body adjacent to the front sidewall. The hard disk drive includes a first end adjacent to the front sidewall and a second end parallel to and opposite to the first end. The hard disk drive is mounted at a slant to the top wall, at an angle of ?, and the distance between the first end and the top wall is less than the distance between the second end and the top wall, to slant up the hard disk drive, allowing the thickness of a front portion of the main body adjacent to the front sidewall to be thinner and cosmetically sleeker.

Abstract: The present invention discloses an XY platform device with nanoscale precision including an optical pickup head for focusing and seeking the tracks of an optical data storage medium; a servo device for driving the optical pickup head to move in focusing and radial directions; a carrier platform for receiving a testing object thereon and providing a connecting member to be connected with the optical pickup head. With the focusing and radial movements of the optical pickup head, the carrier platform is driven to move accordingly, and thus achieving the high-precision and low-cost effects.
