Abstract:
PURPOSE: A disk exposure type disk drive device is provided to prevent the inflow of foreign substances by covering a disk part exposed from a body casing through a slot. CONSTITUTION: A body casing (110) includes a first slot loading a disk into a first side. A protective cover (150) covers a disk part exposed from the body casing through the first slot. The protective cover includes a first cover placed on the first side of the body casing. A disk loading unit is installed in the body casing. The disk loading unit includes a loading roller operated to load the disk. A sensor (131) is installed on the first cover to sense the disk.
Abstract:
PURPOSE: A disk loading device is provided to prevent interference or collision between components between a pickup up and the disk loading device. CONSTITUTION: A large diameter loading lever(50) is moved by a pair of guide arms. A slide cam unit(60) is moved by a small diameter loading lever of the large diameter loading lever. A chuck unit(70) is installed between the guide arms and a disc selecting unit. The chuck unit is operated by the slide cam unit. The chuck unit fixes a disc.
Abstract:
An optical disc drive is provided to reduce the vibration of a traverse deck by decreasing change in load applied to left and right sides of the traverse deck. An optical disc drive comprises a main deck(10), a tray(20), a turn table(32), an optical pickup(33), a traverse deck(30), and a balancer(50). The tray is installed at the main deck to move back and forth and loads/unloads an optical disc thereon. The turn table rotates the optical disc. The optical pickup is installed to move back and forth and records/reproduces data by illuminating light to the optical disc mounted on the turn table. The traverse deck is provided with the turn table at its front side and the optical pickup. The balancer is disposed on the traverse deck and adjusts the balance of load applied to left/right sides of the traverse deck.
Abstract:
본 발명은 트레버스 데크 좌우 양측의 밸런싱을 맞출 수 있도록 되어 있는 광 디스크 드라이브에 관한 것이다. 본 발명에 따른 광 디스크 드라이브는 메인 데크과, 메인 데크에 전후 방향으로 진퇴이동 가능하게 설치되어 광 디스크가 로딩 및 언로딩되게 하는 트레이와, 광 디스크가 안착되어 회전하게 하는 턴테이블과, 전후 방향을 진퇴이동 가능하게 설치되어 턴테이블에 안착된 광 디스크에 광을 조사하여 정보를 기록/재생하는 광 픽업과, 전방측에 턴테이블이 설치되고 광 픽업이 진퇴이동 가능하게 설치되는 트레버스 데크를 포함한 것으로, 트레버스 데크에는 트레버스 데크의 좌우 양측에 작용하는 하중의 밸런싱의 맞추는 밸런서가 설치되어 있으므로, 턴테이블 및 광 디스크의 회전은 안정적으로 이루어질 수 있게 되며 그에 따라 광 디스크 드라이브가 동작하는 과정에서 발생하는 진동 및 소음을 줄일 수 있게 되는 효과가 있다.
Abstract:
PURPOSE: A disc player and a driving method thereof are provided to accurately control a tray even in rapid entrance/exit by performing a driving motor stop command at a plurality of slits after detecting a signal. CONSTITUTION: A disc player is composed of a body(10), a tray(100), a sensor(200), and a plurality of slits(310~360). The tray includes first and second grooves(101,102). The discs of first and second sizes are loaded on the first and second grooves. The tray slides to a play unit and goes in/out. The sensor senses whether a disc is loaded on the tray or not. The sensor senses the size, the entrance into and the exit from the tray of the disc loaded. The slits are formed to penetrate the tray with different length in order to be corresponded to the sensor.
Abstract:
A dust removal apparatus of an optical device is provided to control high frequency applied to an actuator by using a microcomputer so as to remove dust effectively and enhance play and recording performance of the optical device. A dust removal apparatus of an optical device comprises an objective lens(31), an actuator(32), a microcomputer(33), and a dust amount sensor(35). The objective lens condenses laser beams. The actuator controls tracking and focus by driving the objective lens, and removes impurities attached to the objective lens by generating vibration. The microcomputer compares an RF signal reflected from an optical disk with a pre-set RF signal to judge whether impurities are attached to the lens, and controls the drive of the actuator and the frequency applied to the actuator. The dust amount sensor senses the dust amount attached to the objective lens.
