摘要： A method of recording and reproducing an optical recording medium which detects a defocus and a tilt of the optical recording medium and compensates the detected defocus and tilt in a high-density optical recording medium. In a free running state in which only a focus servo is turned on, the amount of defocus offset that corresponds to a maximum level of a tracking error signal is detected in a plurality of positions on inner and outer peripheries of a disc, and a tilt-zero in the respective position is detected and stored, so that a tilt servo and a focus servo are performed with the value stored in the corresponding position during an actual recording/reproduction. The method can prevent the deterioration of quality of data due the defocus during recording/reproduction, enabling real time recording by quickly stabilizing the focus servo, and stable operation of the system. Also, the method can follow corresponding tracks with a rapid stabilization of servo during a search or seek, and detect and compensate for the tilt stably and accurately in the high-density optical disc. The method can also prevent the deterioration of quality of data and a detrack due to the tilt during recording/reproduction, and thus achieve stable operation of the system.

摘要： A system and method for handling events issued as a result of error conditions in the operation of an optical disc drive include suspending processing of commanded operations in the disc drive while attempting to recover from the error condition. The recovery attempt can include increasing levels of recovery effort, such as dynamically recalibrating various components in the disc drive. The system can also determine whether a previous notice was received for the same error condition. If so, the system can determine whether excessive recovery attempts have been initiated based criteria such as the time between the notices, and/or the number of notices, for the same error condition. The recovery attempts are aborted when they become excessive. If the recovery attempt is successful, the interrupted operation is resumed at the point where the processing was suspended, such as during a write or read command.

摘要： An optical disc drive for accessing data stored on an optical disc is disclosed. The optical disc drive includes: a sled inside the optical disc drive, the sled sliding relative to the optical disc; an actuator on the sled, the actuator wobbling relative to the optical disc; and a control circuitry for controlling the optical disc drive. The control circuitry includes a focus compensation device for compensating focus errors caused by wobbles of the optical disc generated during rotations of the optical disc; and a high frequency compensator for compensating focus errors caused by wobbles of the optical disc generated during rotations of the optical disc at a frequency higher than a predetermined frequency. The focus compensation device controls the actuator to wobble upward and downward according to wobbles of the optical disc so as to substantially keep up wobbles of the actuator with the wobbles of the optical disc. When the optical disc is rotated at a frequency higher than the predetermined frequency, the high frequency compensator controls the actuator to wobble upward and downward so as to substantially keep up the wobbles of the actuator with the wobbles of the optical disc.

摘要： A recording and reproduction apparatus for a recording medium including a plurality of information layers includes a focusing signal generation section for generating focusing signals F+ and F− in accordance with a light beam reflected by the recording medium; a focusing control section for generating a focusing error signal in accordance with a difference between the focusing signals F+ and F−, and performing focusing control for maintaining a distance between a focal point of the light beam and a target information layer within a prescribed tolerable range; and a gain setting section for setting a focusing servo gain in accordance with the focusing error signal. The focusing signal generation section generates the focusing signals F+ F− so that values of components thereof based on the light beam reflected by an information layer other than the target information layer are substantially equal while focusing control is being performed.

摘要： For performing a retry in a data storage device, a spin jitter value corresponding to a desired sector of a disc is determined. A read timing is adjusted according to the spin jitter value of the desired sector. A retry of a data read is performed for the desired sector with the adjusted read timing. Thus, the present invention accounts for eccentricity of the disc as indicated by the spin jitter value during retry of the data read operation.

摘要： A tilt compensation apparatus and method minimizes a coma aberration generated due to a tilt of an optical disc by canceling a tilt offset amount of a tilt sensor. An objective lens converges a light emitted by a light source mounted on an optical pickup and irradiating the light onto a recording surface of the optical disc. An objective lens tilt actuator controls tilt of the objective lens. An objective lens tilt sensor detects an amount of tilt of the objective lens. An optical disc tilt sensor detects an amount of tilt of the optical disc. An operator computes an amount of relative tilt between the objective lens and the optical disc in accordance with the amount of tilt detected by the objective lens tilt sensor and the amount of tilt detected by the optical disc tilt sensor. A memory part stores an amount of offset of tilt generated in each of the tilt sensors. An offset adjuster adjusts an amount of offset of tilt of the optical pickup in accordance with the amount of offset of tilt stored in the memory part.

摘要： An optical disk apparatus includes a main chassis and a sub-chassis provided on a drawer, and has a skew adjusting mechanism of the main chassis and the sub-chassis which is skew-adjusted with reference to a rotational axis in tangential direction XT, which is parallel to a spot trajectory L of an optical pickup and located in the vicinity of the spot trajectory L, and a rotational axis in radial direction XR perpendicular to the rotational axis in tangential direction XT. This enables the skew adjustment in which a change in height of the optical pickup is small during the adjustment and distortion is small.
