Abstract: An optical disc apparatus comprises, an optical pickup, a signal extracting unit for reading address information and an RF signal from an optical disc based on signal read by the optical pickup, and a main controller for performing jitter control and focus control. At an initial reading of the optical disc, the main controller determines whether an address information detector succeeds in reading the address information. If not successful (NO in S3), the main controller offsets a defocus position to two points in plus and minus directions from a defocus position giving best jitter (S7), calculates an approximate curve of signal level characteristics with a peak value (S8), and adjusts and allows the defocus value to correspond to this peak value (S9). If the optical disc apparatus cannot read address information, depending on the defocus value, it increases the signal level of the address information by the defocus position adjustment.

Abstract: In an optical head according to the present invention, an act base on which an objective lens is arranged is formed in a rectangular shape with through holes formed in four corners thereof. A base on which a collimating lens is arranged has projections to engage with the through holes in correspondence with the through holes when the act base is arranged. With the through holes of the act base engaged with the projections of the base, an adhesive is injected to the through holes to thereby fix the act base to the base. This improves the accuracy in bonding between the base and the act base, and permits laser light of a more stable intensity accordingly to be irradiated to the optical disc, thus permitting suppressing failure involved in data recording or reading.

Abstract: An optical pickup device comprises a lens holder to hold an objective lens for irradiating a laser beam onto an optical disc; outer and inner circumferential side wires fixed at one ends thereof to outer and inner circumferential sides of the lens holder and extending substantially in parallel to the optical disc; a suspension holder for suspending and supporting the other ends of the outer and inner wires to cantilever the lens holder; and a magnetic drive circuit for driving the lens holder in a focusing direction and a tracking direction. The outer wires have an effective length longer than that of the inner wires. This makes it possible to tilt the objective lens so as to compensate the tilt of the optical disc, if any, at the time of recording and reproduction, thereby reducing jitter and improving recording and reproduction performance of the optical pickup device with simple structure.

Abstract: An optical pickup of an optical disc apparatus has a lens holder for holding an objective lens is pivoted with a guide shaft slidably in a direction in parallel with an optical axis of the objective lens and rotatably around the guide shaft in a direction perpendicular to the optical axis. For focusing a laser beam on a data recording face of an optical disc in a focusing on operation, a wobble signal of rectangular waveform having a predetermined voltage and a predetermined frequency is applied to a tracking coil for reciprocally displacing the lens holder in the direction perpendicular to the optical axis, while a focusing coil is driven for moving the lens holder in the direction in parallel with the optical axis. Thus, the lens holder can be moved smoothly along the guide shaft, so that the possibility of failure of the focusing the laser beam on the optical disc can be reduced drastically.
