    摘要： A device for detecting the abnormality of an optical pick-up head has a laser diode for emitting a light beam through an optical system to a reference reflective region formed at a predetermined portion of an optical disk, a photosensor for receiving a reflected light from the reflective region through the optical system, and a photosensor for detecting directly the light amount of the laser diode. The difference or a ratio of the detection signals of the photosensors is obtained, and the difference or the ratio is compared with a predetermined value. When the compared result exceeds a predetermined value, the result is decided to be an abnormality of the pick-up head.

    摘要： In a system for detecting defects on an optical surface, a disk to be inspected is mounted on a turntable, and is attracted on the surface of the turntable. On the disk is provided an optical head having an objective lens located at its focal point on the surface of the disk. A laser beam emitted from a laser unit is projected through the optical head onto the disk, is reflected on the disk, and is then directed through the optical head to a photo detector. The optical head is moved in the radial direction of the disk as the turntable is rotated, and the disk is helically scanned by the laser beam. Only a defect signal is extracted from an electrical signal generated from the photo detector in a defect signal generator. The defect signal is compared in a data processing unit, and is converted to defect information of different size. When it is judged that a prescribed region on the surface of the disk is scanned by a position signal from a position sensor for detecting the position of the optical head, the data processing unit generates an address, and the defect information is stored in each size in specific assigned locations of the RAM. The defect information thus stored is displayed on a CRT or is printed out by a printer.

    摘要： An information recording and reproducing apparatus for copying information from a master medium to a plurality of copying media, including a master medium reproducing unit for reading information from the master medium; a plurality of copying-medium recording unit for writing the information read from the master medium onto copying media; and a copying operation controlling unit for controlling the above-described recording and reproducing units; wherein a copying process is started when the copying operation controlling unit detects the mounting of a master medium into the master medium reproducing unit. At the end of a copying process, successful media are automatically ejected from the apparatus, whereas unsuccessful ones remain in the apparatus without being ejected, so that a user can easily know which media are successful and which ones are unsuccessful.
