    摘要: Provided is an optical disc device capable of correcting a value of a control parameter during an operation of reading information from an optical disc medium. The optical disc device for reading the information recorded on the optical disc medium under an operation condition corresponding to a value set with respect to a predetermined control parameter corrects the value of the predetermined control parameter by repeatedly executing, while an operation of reading the information from the optical disc medium is being performed, processing of: acquiring, with respect to two values of the predetermined control parameter, evaluation values indicating accuracy of the reading of the information from the optical disc medium, respectively; and updating the value of the predetermined control parameter based on the two acquired evaluation values.

    摘要: A lens support mechanism including a semiconductor laser 10 for emitting a laser beam, an optical head enclosure 3 to which the semiconductor laser 10 is fixed and located, a collimator lens 21 disposed coaxially with the laser beam emitted from the semiconductor laser 10, a resin cylinder 22 formed in a cylindrical shape so as to fix and locate the collimator lens 21 to the inner surface thereof, and a cylindrical member 23 fitted to the resin cylinder 22 on a side of the collimator lens 21 opposite to the semiconductor laser 10 and formed so as to be fixed to the optical head enclosure 3. The cylindrical member 23 has almost the same linear expansion coefficient as that of the optical head enclosure 3.

    摘要: An optical disk device includes an optical pickup, and a controller. The optical pickup emits light on an optical disk, and detects return light from the optical disk. The controller performs a focus control based on a focus error signal corresponding to the return light detected by the optical pickup, and performs a tracking control based on a tracking error signal corresponding to the return light detected by the optical pickup. The controller finds a relation of an amount of deviation in a tracking balance of the tracking error signal relative to a change in a focus balance of the focus error signal while the tracking control is stopped prior to reproduction of the optical disk. The controller corrects the deviation in the tracking balance attributable to the change in the focus balance based on the relation while the focus balance is adjusted.
