The tilt compensating device includes: an optical pickup; a tilt adjusting unit that adjusts a tilt angle of the optical pickup; a jitter detecting unit that detects an amount of jitter in a reproduction signal output from the optical pickup; and a controlling unit that monitors speed at which the optical recording medium operates using a phase-locked loop (PLL) signal generated from the reproduction signal and the degree of focus of the optical pickup, performs an operation to return to a normal state if any abnormality occurs, and controls operation of the tilt adjusting unit by comparing an amount of jitter detected at regular intervals against a reference.

Abstract: An apparatus and a method of playing an optical recording medium, including a method of compensating for a tilt by a real time tilt detection before and during a playing operation of the optical recording medium. A tilt compensating apparatus includes an optical pickup, a tilt adjuster which adjust a tilt of the optical pickup, a jitter detector which detects a jittering amount of a playing signal generated from the optical pickup, and a tilt controller which controls operations of the tilt adjuster so as to have the jittering amount become minimum by comparing the jittering amount detected before a reproduction of a content of the optical recording medium with a first jittering reference value, and comparing the jittering amount detected during the reproducing of the optical recording medium, per a certain period, with a second reference value. Since the reproduction of the optical recording medium is performed after a tilt compensation, it takes a shorter time to start the reproduction operation.

Abstract: A method for compensating for tilt in reproducing an optical reproducing medium is performed by determining an initial tilt driving direction so as to not interrupt a reproducer when tilt compensation is performed on the optical recording medium. The tilt compensation method involves comparing the amount of jitter detected over a certain period of time when the optical recording medium is reproduced with a reference value; determining the direction of tilt compensation in the direction of reproducing a track of the optical recording medium, before performing tilt compensation, when the amount of jitter detected, according to a comparison result of the comparator, exceeds a reference value; and resuming reproduction of the optical recording medium after performing tilt compensation so that the jitter decreases in the direction of the determined tilt compensation.

Abstract: Disclosed is a method for searching a boundary point between at least one recordable area for recording data and at least one non-recordable area of a Power Calibration Area (PCA) in an optical disc. According to the method, an optical disc drive moves to a first point in the PCA, and checks whether the first point is a recordable or a non-recordable area. Then, based on a result of the checking, the optical disc drive moves to the right or left for a second point located in a first-designated space that varies by movement count, and checks whether the second point is a recordable area or a non-recordable area. Thereafter, the optical disc drive repeats the moving and checking operation until a first non-recordable area adjacent to the recordable area is searched. In this manner, the drive can quickly search the boundary point between recordable areas and non-recordable areas.

Abstract: A method for adjusting a deviation occurring on seeking a burst cutting area (BCA) in an optical disc, including, when an optical disc is loaded into an optical reproducing apparatus, reading data from a predetermined position of the BCA, reading data from the predetermined position of the BCA and first and second points at predetermined distances from left and right sides of the predetermined position of the BCA, processing the read data to determine whether the read data corresponds to BCA data, and if the data read from all of the predetermined position of the BCA and the first and second points corresponds to the BCA data, determining the predetermined position of the BCA as a final position of the BCA in which a deviation has been adjusted and storing information as to the final position of the BCA as information to seek the burst cutting area in a memory of the optical reproducing apparatus.

Abstract: A method and apparatus for correcting a tilt without repeatedly calculating a tilt angle with respect to a corresponding recording or reproducing sector, by managing the tilt angle detected with respect to each recording sector of a disc in a disc drive. If a tilt of a disc mounted in the disc drive is detected, a memory is searched for a tilt angle for a sector of the disc in which the tilt is detected. If no tilt angle is found in the memory, a tilt angle is calculated for the sector based on the detected tilt of the disc, the tilt of the disc is corrected, and the calculated tilt angle is stored in the memory to be used for the sector. If a tilt angle is found in the memory, the tilt of the sector is corrected using the found tilt angle.

The tilt adjusting apparatus includes a jitter detection unit, which detects the jitter quantity of a reproduction signal picked up by a pickup unit, a jitter data preprocessing unit, which filters the jitter quantity in a predetermined window interval unit and obtains a value of an objective function from the filtered jitter data in each predetermined time unit, and a tilt control unit, which obtains a tilt adjusting value by performing tilt control using the value of the objective function and feeds the obtained tilt adjusting value back to a tilt driving unit. According to the tilt-adjusting method and apparatus, when data on an optical disc with a tilt defect is reproduced, quantified jitter values being fed back are adjusted.
