Description

technical field [0001] The present invention relates to a device and method for opening the shutter of a case of an optical disc recording and playback device, in particular to an opening device for opening the case shutter before the case is pushed into the optical disc recording and playback device. Background technique [0002] An optical disc D like a digital versatile disc (DVD) is a recording medium on which information is recorded / reproduced by a recording and reproducing apparatus. Information is recorded / reproduced to / from the concentric tracks of the disc. Such an optical disk is mounted on a turntable by a disk loading device so as to be able to be rotated by a rotating device. When the optical disc D rotates, the optical head device moves in the radial direction of the optical disc D, and projects a laser beam to the disc track. As a result, information is recorded on the disc, or information is reproduced from the disc. [0003] figure 1 Showing a convention...
