摘要： An improved light-readable information recording disc is provided in which the optical data storage structure consists of either lands and pits or lands and bumps, in which the depth of the pits or the height of the bumps, respectively, is controlled to approximate one-half of the wavelength of the light striking the optical data storage structure. Unexpected and surprising improvements over conventional optical recording discs is achieved through increased light intensity differences detected at the changeover between pits/bumps and lands.

摘要： Methods and apparatus for recording and playing back multi-channel digital audio having different sampling rates for different channels are provided. Recording is accomplished by sampling a plurality of channels of audio data and arranging the samples of the plurality of channels of audio data in most nearly the order needed during playback. Playback is accomplished by accessing the samples of the plurality of channels of audio data and converting the samples from digital to analog form. The playback may include deriving audio signals in a different format from the format in which the programming is recorded.
