    摘要: An optical disk apparatus for reproducing or recording and reproducing two or more sorts of optical disks whose recording plane heights are different is arranged to reproduce or record data from or on the optical disk transparently to the user and without the users intricate operations. For this purpose, the optical disk apparatus provides a disk discriminating circuit for discriminating the disks whose recording plane heights are different. The disk discriminating circuit operates to discriminate the disk before reproducing or recording the disk mounted to the optical disk apparatus and switch the optical system and the circuit system to the suitable ones to the discriminated disk and then reproduce or record the data from or on the disk.

    摘要: An optical disc apparatus for recording information and/or reproducing on an optical disc which has at least two recording layers including layer 0 and layer 1 reproducible from one side of the disc. The apparatus includes an optical pickup having a laser source, an objective lens, and an actuator. A controller is provided which obtains a present layer information of a sector recording layer from light reflected from the disc, confirms a target layer information of a target recording layer, judges whether the present layer information is the same as the target layer information, and outputs a first control signal to the actuator when it is judged that the present layer information is layer 0 and the target layer information is layer 1, and outputs a second control signal to a slider.

    摘要: The present invention provides an optical disk apparatus capable of stably performing a layer jump on an optical disk having plural recording layers and non-uniform interlayer distances. In an optical disk with at least three recording layers and non-uniform interlayer distances between respective recording layers, if a layer jump is carried out from a first recording layer to a second recording layer, a distance from the first recording layer to the second recording layer is obtained and driving voltages set according to the distance are applied to an actuator for the layer jump to carry out the layer jump. At this time, interlayer distances for combinations of the respective recording layers and applied driving voltages thereto are stored in a memory in advance and when necessary, corresponding driving voltages are read out from the memory and are set for the layer jump.
