  • Media type detection using a lock indicator
    Patent number: 8018805
    Abstract: A method for detecting a media type of an optical disc system comprising the steps of (A) checking for a first wobble signal associated with a first media type, (B) if step (A) detects the first wobble signal, operating the optical disc system as the first media type, (C) checking for a second wobble signal associated with a second media type, and (D) if step (C) detects the second wobble signal, operating the optical disc system as the second media type.

  • Severe asymmetry compensator for optical recording PRML read channel
    Patent number: 7161522
    Abstract: An apparatus comprising an analog-to-digital converter, a compensation circuit, a partial response equalizer and a non-adaptive Viterbi decoder. The analog-to-digital converter may be configured to convert an input analog signal into a digital signal. The compensation circuit may be configured to generate an output signal by clipping the digital signal. The partial response equalizer circuit may be configured to shape the output signal into a pre-defined target with a delay operator. The decoder may be configured to calculate a minimum error between data in the output signal and other possible data sequences.
