Abstract: A loop filter and a method for adjusting its compensating current to make a control voltage of the loop filter more stable. The loop filter includes a charge/discharge path for receiving a control current and constituted by a first resister and a capacitor, a second resistor connected to the first terminal of the first resistor, an OP amplifier having an output terminal connected to the second resistor, a first input terminal connected to the capacitor, and a second input terminal, and a compensating unit connected to the output and second terminals of the second resistor. The loop filter further comprises a current source to provide a compensating current to the compensating unit. The loop filter utilizes the compensating unit to compensate the offset between the two input terminals of the amplifier. Therefore, the loop current of the OP amplifier can be reduced or eliminated.

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.
