  • Patent number: 6072757
    Abstract: A type of disk in a reproducing device is accurately determined prior to data reproduction. To determine whether the disk type is Compact Disk (CD) or Digital Video Disk (DVD), a track pitch on the disk is examined, while the difference between the DVD Single Layer and DVD Dual layer is based on disk reflectance values. When thus determined disk type turns out to be incorrect, an operation is carried out for estimating the correct disk type based on the highest likelihood of the disk type following the initial (incorrect) decision. The process is carried out until the correct disk type is identified, or the disk is determined to be unusable.

  • Patent number: 6072758
    Abstract: In accordance with the invention, an apparatus and method are provided in which it is possible to determine a type of disc which has been loaded before servoing is locked. A disc is rotated by a spindle motor, and a pickup is gradually moved toward the disc from a position spaced apart from the disc. A peak value of an obtained reflection is detected by a peak hold circuit is stored into a CPU. If the disc is a DVD (by way of example), a single layer DVD has a reflectivity higher than that of a double layer DVD. Accordingly, a single layer DVD and a double layer DVD can be discriminated from each other from the value of the peak reflection value obtained by the peak hold circuit.

  • Patent number: 5974014
    Abstract: A disc reproducing apparatus comprising a means for reproducing data recorded in a disc, a means for making a decision as to whether the reproduced data are proper or not, a means for detecting a face-down state of the disc in response to the result of the decision, and a means for controlling the driving of the disc in response to the result of the detection. When a disc (DVD) loaded in a normal state is rotated clockwise, the point of reproduction is gradually shifted toward the outermost of the disc. However, when a disc loaded in a face-down state is rotated, the point of reproduction is shifted toward the innermost of the disc, so that the required continuity of addresses fails to be ensured. Thus, the face-down state of the loaded disc can be detected from the result of the decision indicating non-continuity of the addresses.

  • Patent number: 5878184
    Abstract: A sector address is obtained even when a playback signal is missed by incrementing the number of interpolations n when determined that error correction of read-out data is not possible, and incrementing and storing in a buffer "address" the contents of a work area B when the number of interpolations n is less than a preset value "Max". When the interpolation address calculation process has been repeated the prescribed number of times "Max" an emergency process is carried out.
