摘要： A compact high-density optical disc capable of securing recording/reproducing characteristics and high-density recording capacity. The high-density optical disc has a whole diameter of 80 mm or less to 28 mm, a whole thickness in a range of 0.3–0.7 mm, and a position where data starts being recorded in a range of 27–45 mm of the diameter. Thus, an existing disc drive can be used, the size of the high-density optical disc can be reduced, and high-density recording capacity can be secured.

摘要： A disk cartridge and a disk drive apparatus. The disk cartridge has a reflector to identify the type of disk, and the disk drive apparatus has an optical emitter/detector to irradiate light on the reflector and detect light reflected from the reflector to identify the type of disk. A large number of identification marks can be provided by changing the angle of reflection and the amount of light reflected from the reflector. Accordingly, disks of various capacities, products and formats can be individually identified.

摘要： A four-axial driving actuator for an optical pickup with improved bobbin dynamic characteristics, in which the winding starting ports for a focus coil, tracking coil, and tilt coil are separate from one another, and the winding end ports thereof are combined as a common ground. The four-axial driving actuator includes: a base; a holder fixed on the base; a bobbin to which an objective lens is fixed; spring wires connected between the bobbin and the holder; and a magnetic driving unit driving the bobbin in the focus, track, or tilt direction with a focus coil, a tracking coil, and a tilt coil, wherein the magnetic driving unit comprises a circuit unit including winding starting ports for the focus coil, tracking coil, and tilt coil, and a common ground port at which winding end ports for the focus coil, tracking coil, and tilt coil are grounded, and the circuit unit applies a voltage to the tracking coil, tracking coil, and tilt coil. In the four-axial driving actuator for an optical pickup, the bobbin and the holder are connected with only four wires serving as electric wires, so that moving characteristics of the bobbin are improved and the assembly time is reduced.

摘要： A disk clamping apparatus for a disk player includes a turntable for receiving a disk, a disk clamper which clamps the disk placed on the turntable, and first and second magnetic bodies which are mounted in the corresponding turntable and the disk clamper and provide a clamping force to the disk by acting a reciprocal magnetic force on the turntable and the disk clamper. The first and second magnetic bodies are opposite to each other and partially overlap each other. In the disk clamping apparatus having the above structure, the variation in a clamping force caused by the variation in thickness of disks, received by the disk clamping apparatus, is very small. Accordingly, clamping and de-clamping of the disks having different thickness can be smoothly performed.

摘要： A disk cartridge includes a case which receives a disk thereon, a cover which is installed on the case and includes an opening, and a shutter which is movably installed in the case, in a lower direction of the disk, to open and close an aperture formed on the case. The disk cartridge has guide holes formed on the case along a trace of the shutter, and support members formed on the shutter. The support members are guided along the guide holes while having ends thereof interfering with peripherals of the guide holes. Therefore, since the peripherals of the guide holes interfere with the ends of the support members, the shutter is prevented from being deformed even where an external force is applied to the shutter through the aperture, in a closed state of the shutter.

摘要： A disk cartridge includes a case which contains a disk, and a shutter which opens/closes at least one opening formed in the case. The shutter is configured to be foldable around upper and lower surfaces of the case, and slides on the upper and lower surfaces of the case to open/close the opening. Since the shutter opens/closes the opening while being folded around the upper and lower surfaces of the case, a movable distance of the shutter for opening/closing the opening can be fully accommodated even though the size of the disk cartridge is reduced. In addition, applying the configuration of the shutter to a double-sided disk cartridge prevents an inflow of dust from entering into the double-sided disk cartridge since the shutter closes an opening, which is not in use, during a recording/reproducing operation.
