摘要： A disc drive unit capable of preventing occurrence of errors in a recording system such as a CD or a DVD, using an optical head for recording data on a disc or reproducing data recorded on the disc. A disc tray is adapted to accommodate the disc, and load and unload the disc. A top cover is arranged above the disc. The top cover is formed therein with a concave and convex part for avoiding positioning a node of each of vibration modes (0, n) (where n=2, 3, 4) caused by a critical rotating speed of the disc, at a position right above the optical head.

摘要： There is provided a disc drive by which the fluid loss of a disc is reduced and the electric power consumption of a spindle motor can be decreased. In the disc drive according to the present invention, a rotation load reducing member is provided between a top cover and the disc. The rotation load reducing member is movably supported by a clearance adjustment member. While the disc is rotating, the rotation load reducing member is moved in the direction approaching the disc. Thereby, the thickness of an air layer on the upper surface of the disc is decreased.

摘要： Since a disc vibrates in a natural mode at a predetermined rotation speed, a variation in a tilt of the disc relative to an optical head is caused. As a result, the read/write performance of a disc drive is deteriorated. The disc drive has a disc tilt database for recording a relative tilt angle of the disc in a tangential direction thereof associated with the disc natural mode and the disc rotation speed at which such tilt occurs, a circuit for detecting a disc rotation speed, and a tilt drive circuit. An objective lens is tilted so that the relative tilt angle is corrected, and thus, stable read/write performance of the disc drive is achieved.

摘要： The invention makes it possible to carry out an emergency eject motion without attaching and detaching teeth between gears in a transmission system of a driving force of a loading motor, in an optical disc apparatus. At least one of gear units in a gear train constructing a transmission system between a loading motor and a disc moving mechanism is structured such that a driving gear is coupled in an inner diameter side of a large diameter driven gear in such a manner as to be movable in an axial direction and be rotatable integrally with the driven gear, and the driving gear moves and displaces in an axial direction with respect to the driven gear, thereby being canceled the coupling with the driven gear while keeping an engagement with a gear in the next stage, canceling the coupling by an external force by a manual operation so as to set the transmission system to a disconnection state at a time of an emergency eject, making the disc moving mechanism carry out a disc discharge motion by the external force, and discharging an optical disc out of the apparatus.

摘要： An optical disc drive may include a tray movable for the sake of mounting and dismounting a disc, a disc rotation mechanism arranged at the center to rotate the disc, and a pickup arranged on a backside of the center to write and read the disc within a housing. The optical disc drive may be arranged with a first opening for inhaling outside air in a height range between the bottom surface of the tray and the proximity to the bottom end of the pickup on a back surface or a side surface around a corner on a right side viewed from the backside of the housing, and a second opening for exhausting internal air, arranged higher than a top surface of the tray on the back surface or a side surface around a corner on a left side viewed from the backside.

摘要： An optical disc apparatus including first to fourth disc guides. At the end of disc loading, the first one, in a fixed position, contacts a peripheral side face of the optical disc at a first point thereon to support the disc; the second one has a plane opposite to the peripheral side face which contacts the peripheral side face of the optical disc at a second point to support the disc while restrained from moving away from the side face; the third one contacts the peripheral side face of the optical disc at a third point to support the disc while biased by a spring; and the fourth one contacts the side face at a fourth point while biased by a spring to support the disc, and is restrained from moving against the resilience of the spring. The disc, supported by those disc guides, is chucked by a clamper.
