摘要： The data selector 59 provides the recording signal Data 1 as LD recording signal LD Data 1 and the output control signal Data 3′ as LD recording signal LD Data 3, and fixes the LD recording signal LD Data 2 to H level. The S&H select circuit 58 supplies an inverted one of the NRZI signal to the enable terminal of the sample and hold circuit 53. The sample and hold circuit 53 samples an output of the bias power 1 part and supplies it as LD control signal LDC 2 to the APC circuit 55. Thus, the bias power 1 being a light power of the multi-pulse is sampled by the sample and hold circuit 53 and controlled by the APC circuit 55 as will be discussed later.

摘要： An optical pickup device for condensing the light from a light source on a signal recording surface of an optical recording medium, such as an optical disc. A semi-spherical lens of the optical pickup device has a surface 9b facing an optical disc 20 and has a pre-set refractive index. The optical pickup device also has a slider 12 adapted for securing the lens 9 and for being in sliding contact with an optical disc 20, and a spring plate 13 adapted for thrusting and supporting the slider in sliding contact with the optical disc 20. With the optical pickup device, high density reproduction may be realized, while the tolerance value for warping during disc molding or the tolerance value for warping due to moisture absorption may be increased. In addition, the production yield and the degree of freedom in selecting the disc materials may be improved.

摘要： Apparatus for detecting noise signals, such as may be due to dropout, in a video signal includes a first detector for detecting positive and negative noise signals included in the positive portion of an input video signal, such as the video information portion, and a second detector for detecting positive and negative noise signals included in the negative portion of that video signal, such as the synchronizing signal portion. An output noise indication representing noise detected in the video and synchronizing portions of the input signal is produced as a function of the outputs from the first and second detectors.
