摘要： A disc drive comprises a main body equipped with a turntable for rotating a disc, a disc tray movable with respect to the main body between a disc loaded position and a disc eject position to transport the disc to the disc loaded position, and a disc clamper for holding the disc transported by the disc tray between the turntable and the disc clamper. The disc drive further includes a disc clamper displacement mechanism provided on the disc tray to make contact with the disc clamper to displace the disc clamper upward when the disc tray is moved from the disc loaded position to the disc eject position so as to prevent obstruction of the movement of the disc tray. This mechanism includes an inclined surface formed on at least a portion of the disc tray to the rear of a disc supporting portion and a reinforcing portion connected to the rear of the inclined surface. According to this structure, the disc clamper does not obstruct the movement of the disc tray, and since a space created underneath the disc tray is utilized to provide ribs underneath the reinforcing portion and the inclined surface, which increase the strength of the disc tray and prevent cambering or warpage of the disc tray.

摘要： A skew adjustment mechanism for an optical pick-up used in an optical disc drive is disclosed, in which the optical pick-up is freely movable in a radial direction of an optical disc along a guide rod for playing back or recording and playing back information recorded on the optical disc. The optical pick-up includes a pick-up base having a first end and a second end opposite to the first end, the first end being slidably connected to the guide rod. The tangential skew adjustment mechanism includes a pick-up base displacement mechanism provided on the second end of the pick-up base for rotationally displacing the pick-up base about an axis of the guide rod. The pick-up base displacement mechanism includes a screw which vertically passes through the second end of the pick-up base such that a lower end portion of the screw which protrudes from the bottom surface of the pick-up base is in contact with a sliding surface which is positioned a prescribed distance below the bottom surface of the second end of the pick-up, whereby the pick-up base can be displaced by adjusting the protruding length of the lower end portion of the screw to achieve tangential skew adjustment.

摘要： A sled motor mounting structure is provided with a sled motor which having a rotation shaft and a lead screw which is mounted on the rotation shaft and is in mesh with a mated gear, the rotation shaft being constructed so as to have a play in its axial direction for enabling a smooth rotation; and a stopper provided in front of the tip of the rotation shaft of the sled motor such that the tip of the rotation shaft comes to abutment thereto when the rotation shaft is displaced toward the tip direction thereof within the play due to the rotation of the lead screw which is in mesh with the mated gear, thereby restricting the tip of the rotation shaft from further movement in the axial direction thereof. The stopper is arranged at a prescribed distance from the tip of the rotation shaft when the rotation shaft is moved to the base end within the play. The prescribed distance is set to be less than the play in the axial direction, for example it lies within the range of 0.02 mm-0.05 mm. According to this structure, because there is no resistance exerted on the rotation shaft by a plate spring or the like which is used in the prior art to push a rotation shaft toward the base end, it is possible to smoothly rotate the sled motor without the need for a large torque.
