    摘要： A recording medium enabling type determination and writing possibility determination for various types of disks. Opening and closing means for opening and closing a detection hole of a cartridge forms a plane substantially horizontal level with a reference plane of the cartridge at a position of the detection hole when the detection hole is in a closed state. The cartridge has at least a first detection hole and a second detection hole formed therein. The second detection hole (H1) is opened and closed by the opening and closing means, and the first detection hole (H0) is in an open state at all times. A disk drive apparatus or a disk determining method determines, together with a disk type, determining information contents (for example writing possibility) based on one or a plurality of detection holes formed in the cartridge, on the basis of an open/closed state of the detection hole and a result of the disk type using a signal based on reflected light from the loaded recording medium.

    摘要： A method and apparatus for managing user marks in an optical disc device such as a DVD recorder are provided. At least one user mark prestored in the optical disc device is read and edited. The edited user mark is combined with input video/audio data, and the combined data is recorded as main video/audio data in a data area of an optical disc. This allows a display of the user mark always regardless of the status of a subtitle-on/off mode.

    摘要： The present invention provides an optical disk apparatus in which a first, second, third, and fourth optical disks are selectively installed, the first and second optical disks having different recording film characteristics and both having a single-layer recording layer, the third and fourth optical disks having different recording film characteristics and both having a double-layer recording layer. A control section determines which of the first to fourth optical disks has been installed, on the basis of the level of a reproduction signal from an optical head. Recording media serving as the optical disks are formed so that the light reflectances of a single-layer L-H medium in an initialized state, an L0 layer of a double-layer H-L medium in the initialized state, and an L0 layer of a double-layer L-H medium in an uninitialized state do not overlap the light reflectance of a single-layer H-L medium in the initialized state.
