    摘要： A disc centering device includes a base plate, a chuck which is installed on the base plate, a hub unit which is detachably engaged to the chuck and receives discs to be stacked, disc pushers which are slidably provided outside the hub unit and include corresponding pressure members which center the discs by pushing circumferences of the discs, and a driving unit which slides the disc pushers simultaneously. Accordingly, as the accuracy of centering the discs is improved, discs with data recorded thereon having a uniform quality can be obtained. Additionally, vibration of a rotation body can be minimized due to the simple configuration the disc centering device. Therefore, in view of the simplified maintenance and repair of the disc centering device, the productivity and manufacturability of HDDs can be improved.

    摘要： A substrate inspecting apparatus to inspect a substrate printed on by a print head to determine whether a printing operation is being accurately performed includes a camera unit to photograph the substrate before the substrate is printed on and to photograph the substrate after the substrate is printed on, and a control part to compare a first image of the substrate before the substrate is printed on with a second image of the substrate after the substrate is printed on through the camera unit and to determine whether the printing operation is being accurately performed on the substrate. Thus, the substrate inspecting apparatus is capable of precisely inspecting the substrate during the printing operation and reducing processing time.

    摘要： A disc centering device includes a base plate, a chuck which is installed on the base plate, a hub unit which is detachably engaged to the chuck and receives discs and spacers to be stacked, disc pushers which are slidably provided outside the hub unit and include corresponding pressure members which center the discs by pushing circumferences of the discs, a driving unit which slides the disc pushers, and biasing units which are slidably provided outside the hub unit and push circumferences of the spacers. Accordingly, by performing a spacer biasing along with a disc centering, the accuracy of a centering is increased, thereby providing the discs having data recorded thereon with a uniform quality. Additionally, vibration of a rotation body can be minimized due to the simple configuration of the disc centering device. Furthermore, the productivity and manufacturability of HDDs are improved in view of the simplified maintenance and repair of the same.

    摘要： A servo track writer and a chuck thereof which are capable of maintaining a central axis of a disk hub to be aligned with a rotating axis of a spindle motor adapted to rotate the disk hub, thereby preventing disks mounted on the disk hub from fluctuating. The servo track writer includes a disk hub, on which a plurality of disks are mounted, a magnetic head assembly to write servo information on the disks mounted on the disk hub, a spindle motor to rotate the disk hub, and a chuck to firmly hold the disk hub. The chuck firmly holds the disk hub at a plurality of points to prevent the central axis of the disk hub from being inclined from the rotating axis of the spindle motor.
