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： 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。

摘要： In an auto-exchanger disc apparatus, both a disc cartridge for stocking plural discs and a pickup cartridge having a pickup are provided with common recesses, and a cartridge stocking unit is formed with a projection which is engaged with the recesses, whereby the cartridges can be exchanged for each other and mounted on the disc apparatus. Therefore, the extension and maintenance of the cartridges can be facilitated. When a double-side reproducing operation is performed, the pickup cartridge is turned upside down and then mounted on the disc apparatus, whereby the double-side reproduction can be surely performed by the disc inverting mechanism. Further, disc inclining means is provided to prevent a disc being returned from the disc feeder to the disc cartridge from abutting against the disc cartridge. The disc inclining mechanism and the disc inverting means may be integrally constructed by the same member to reduce the cost. Still further, a cleaning member is provided to some or all of the rollers for feeding the disc to perform a disc cleaning operation as well as a disc feeding operation, thereby preventing dust from being attached to the disc.
摘要翻译：在自动交换盘装置中，用于储存多个盘的盘盒和具有拾取器的拾取盒均设有共同的凹部，并且盒放置单元形成有与凹部接合的突起，由此盒可以彼此交换并安装在盘装置上。因此，可以促进盒的扩展和维护。当执行双面再现操作时，拾取盒被倒置并且然后安装在盘装置上，从而可以通过盘反转机构可靠地执行双面再现。此外，提供盘倾斜装置以防止盘从盘进给器返回到盘盒抵靠盒式盘。盘倾斜机构和盘反转装置可以由相同的构件一体地构造以降低成本。另外，为了进行光盘的一部分或全部的辊的清洁，设置清扫部件，进行光盘的清扫动作以及光盘供给动作，防止灰尘附着在光盘上。
