    摘要: An optical disc drive is has a voice coil motor that carries and moves focal optics to focus a laser beam onto an optical disc The voice coil motor is responsive to input signals which are based on a calibrated temperature. A temperature measurement is made at the voice coil motor for an operating temperature, and a difference is calculated between calibrated and operating temperatures. The temperature differences are used to calculate adjustment in input signals used to drive the voice coil motors.

    摘要: An optical focusing system is configured to generate a data profile, wherein the data profile is configured to provide signals for operation of an actuator. Application of the signals from the data profile results in focus of optics within a label region of an optical disc. An image is printed on the label region of the optical disc while the optics focus on the label region of the optical disc by applying signals to the actuator according to the data profile.
