Abstract: A hard disc drive is provided. The hard disc drive includes a base including a moving region in which an air damping ramp, adjacent to a recording surface of a disc, a slider, and a driving unit, which holds the slider, move. The bottom of the moving region is lower than the air damping ramp, and has a channel that is recessed at the bottom of the moving region and extends along the moving path of the slider. This structure reduces a vortex that forms around a head gimbal assembly (HGA) due to the application of insufficient preload onto HGA or a defective HGA. Accordingly, vibration of the HGA due to the vortex decreases, thus rendering a position error signal (PES) more accurate and reliable.

Abstract translation: 提供硬盘驱动器。 硬盘驱动器包括基座，该基座包括移动区域，在该移动区域中与盘的记录表面相邻的空气阻尼斜坡，滑块和保持滑块的驱动单元移动。 移动区域的底部低于空气阻尼坡道，并且具有凹陷在移动区域的底部并且沿着滑块的移动路径延伸的通道。 由于对HGA或有缺陷的HGA施加不足的预载荷，该结构减少了形成在磁头万向节组件（HGA）周围的涡流。 因此，涡流引起的HGA的振动减小，从而使位置误差信号（PES）更加准确和可靠。 ＆lt;图像＆GT;

Abstract: PURPOSE: An electrophotographic printer is provided to easily replace expendable component with new ones and prevent a photosensitive drum from being damaged by interference of the photosensitive drum and a pre-transfer eraser when the expendable components are replaced. CONSTITUTION: An electrophotographic printer includes a photosensitive drum(1) on which an electrostatic latent image is formed, at least one developer(4K), and a pre-transfer eraser unit(10). The developer has a developing roller for supplying a toner to the electrostatic latent image to develope the image and maintains a developing gap from the photosensitive drum. The pre-transfer eraser unit irradiates light to the developed photosensitive drum to erase charges of a non-image region. The pre-transfer eraser unit includes a pre-transfer eraser lamp(41) for emitting light, and a pre-transfer eraser lens(42) for guiding the light to the photosensitive drum. The pre-transfer eraser lens is moved to a charge-erasing position in proximity to the photosensitive drum and a retreated position distant from the photosensitive drum.
