Abstract: An optical disk drive includes an optical disk drive controller that can test the write channels between the controller and the laser diode driver. Using the results of this testing, the optical disk drive controller adjusts the characteristics of the write channel signals provided to the laser diode driver to correct for one or more detected imperfections in the write channel signals. Both the optical disk drive controller and the laser diode driver have communications ports to facilitate communication. The optical disk drive controller programs the operating characteristics of the laser diode driver so that the laser diode driver can be optimized for the measured characteristics of the write channels.

Abstract: A peak detection circuit with double peak detection stages includes an analog peak detector, an analog-to-digital converter (ADC), and a digital peak detector. The analog peak detector receives an analog input signal, detects a peak value of the analog input signal with a first period, and outputs an analog peak signal. The ADC receives the analog peak signal and converts it into a digital signal. The digital peak detector receives the digital signal, detects the peak value of the digital signal with a second period longer than the first period, and outputs a digital peak signal. Therefore, the analog peak signal will not decay seriously due to the leakage and the digital peak signal can hold the digital peak value for a long time.
