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： 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： 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： The speed of a disc handling operation by a disc apparatus having disc changer capability is significantly increased and, at the same time, the disc handling operation is performed with stability. In the disc apparatus according to this invention, a plurality of reproducing units loaded with discs are moved independently and disc reproduction is started by returning the reproducing units to their dedicated positions. Simultaneous returning of the plurality of reproducing units is prevented and each reproducing unit moves for refuge while reproducing the disc. This novel setup significantly shortens the time for moving the reproducing units for disc reproduction. When continuously reproducing a plurality of discs accommodated in proximity, the plurality of reproducing units are moved in a stacked state rather than independently. This also contributes to a significant reduction of the time in the disc handling operation. Further, when raising the lower reproducing unit in the stack, it is moved together with the upper reproducing unit; when raising the upper reproducing unit, it is separated from the lower reproducing unit for independent movement. This prevents the reproducing units from colliding against each other. The novel constitution significantly enhances ease of use of the disc apparatus.
摘要翻译：通过具有换碟机能力的盘装置的盘处理操作的速度显着增加，并且同时执行盘处理操作。在根据本发明的光盘装置中，装载有光盘的多个再现单元被独立地移动，并且通过使再现单元返回到其专用位置来开始盘再现。防止多个再现单元的同时返回，并且每个再现单元在再现盘时移动避难。这种新颖的设置显着地缩短了用于盘再现的移动再现单元的时间。当连续地再现容纳在接近的多个盘时，多个再现单元以堆叠状态而不是独立地移动。这也有助于在盘处理操作中显着减少时间。此外，当升起堆叠中的下再现单元时，它与上再现单元一起移动; 当升起上再现单元时，它与下再现单元分离以进行独立运动。这防止再现单元相互碰撞。该新颖的构造显着提高了盘装置的易用性。
