摘要： An optical disc having a protection layer for protecting a recording layer located farther from a substrate and having a first recording layer and a second recording layer stacked on one side of the substrate, wherein the reflectance of one of the first and second recording layers is made higher than the reflectance of the other recording layer, and a reproducing device which uses this optical disc. The reproducing device casts a light beam emitted from a single light source onto the first recording layer or the second recording layer via a single objective lens, discriminates which of the first recording layer and the second recording layer the light beam emitted from the light source is cast on, on the basis of the result of detection of a reflected beam from the first recording layer or the second recording layer, moves the objective lens in a direction parallel to the optical axis of the objective lens on the basis of the result of discrimination, and condenses the light beam on the first recording layer or the second recording layer so as to carry out reproduction of information.

摘要： Methods and computer readable media with program instructions for dynamically determining write speeds of an optical media device are provided. In one example, a method includes setting a device set write speed to a maximum write speed of the optical media device, and then verifying that the device set write speed is as just set. If the optical media device is verified to be as just set, a current set write speed is saved. The device set write speed is then decreased by an increment and the device set. The device set write speed is again verified to be as just set, and saved if verified. The method continues to decrease the device set write speed by an increment, set, verify, and save until the device set write speed is set to zero. Only verified set write speeds are presented as options for user interaction for the optical media device.
