摘要： Disclosed is an optical disc drive. The optical disc drive may include a clamp unit for chucking an optical disc; at least one lifting projection protruding from the clamp unit; and a moving force transfer unit for transferring a moving force, of moving the clamp unit in an axial direction of the clamp unit, to the clamp unit through the lifting projection, wherein the moving force transfer unit includes a guide for moving the lifting projection in the axial direction by a movement in a direction perpendicular to the axial direction, and a protective part provided at at least one of both ends of the guide and protecting the lifting projection. Accordingly, when an optical disc rotates at high speed, noise generation at a joined portion between the guide of the moving force transfer unit and the lifting projection can be suppressed.

摘要： A disc-shaped optical data recording medium has a signal recording layer for reading and/or writing data using light, and a 10 µm to 200 µm thick transparent protective layer disposed over the signal recording layer. The optical data recording medium includes a protrusion projecting from the surface of the transparent protective layer on the light-incidence surface side to which light is emitted to the signal recording layer. The protrusion is disposed in an area between a center hole and a clamping area where the optical data recording medium is held when reading and/or writing data in the signal recording layer.

摘要： Drive units for a data medium, e.g. a CD or a DVD, generally comprise a turntable and a clamp. It would be advantageous to provide a drive unit having an improved torque 5 transmission from the rotatable parts of the drive unit to the disc. It would also be desirable to allow a better guiding of the disc into a centered position around the axis of rotation from the supporting surface. To better address one or more of these concerns, an embodiment of the invention provides a drive unit for a data medium, comprising a turntable and a clamp for clamping a data medium onto the turntable, wherein the turntable 10 and the clamp can be moved with respect to each other from an unclamped to a clamped position, and, in the clamped position, the turntable and the clamp comprise a form-fit torque transmission between them.

摘要： A thin disk loading mechanism in which a turntable (36) itself is defined by the contour of a brushless spindle motor, a chucking face for a disk (11) is precisely defined at a predetermined height on a turntable base (46), posts (47) in three directions along a circumference surrounding the periphery of the turntable (36) are planted in the turntable base (46), and a post fore end step portion (47b) and a disk mounting face (36a) of the turntable (36) have accurate predetermined dimensions. When the post fore end step portion (47b) abuts against the lower face (reference plane (L)) of a drive base (15), the relative positions of the disk mounting face (36a) of the turntable (36) and a pickup constructed with reference to the lower face of the drive base (15) are accurately defined.

摘要： Disclosed is a clamping apparatus for a disk drive. The clamping apparatus includes a clamp selectively attached to a turntable to fix a disk, and formed with a hook wing protruding in a centrifugal direction along an outer circumferential edge thereof, a hook section provided with a clamp through-hole through which the clamp is penetrated and which has a diameter smaller than that of the hook wing, and hooking and supporting the hook wing of the clamp, and an unclamping protrusion provided one side between the hook section and the hook wing, and first contacted with the hook section or the hook wing when the disk is unloaded to apply unclamping force. The unclamping protrusion is located at a position most distant from a lifting center of a pickup base having the turntable on which the disk is seated. Thereby, clamping force by which the clamp clamps the disk increases relatively, while the unclamping force for separating the clamp from the turntable decreases relatively, so that operational reliability of the disk drive is improved.
