An optical pickup capable of effectively reducing chromatic aberration is provided. In the optical pickup, a collimating lens (103) including a diverging lens (103b) with diverging power and a focusing lens (103a) with focusing power is arranged on the optical path between a light source (104) and an objective lens (101), wherein assuming that the total focal distance of the collimating lens is f and the focal distance of the diverging lens is fn, the collimating lens satisfies the relationship -1.5 > f/fn . The optical pickup is compatible with both existing digital versatile disks (DVDs), and high-definition (HD)-DVDs, which are not standardized yet, but need a blue light source near 405nm and an objective lens having a numerical aperture of 0.6 or more.

Disclosed is a method for managing conflicting schedules in a mobile communication terminal. The method includes receiving a schedule input by a user in a schedule management mode, determining whether the new schedule currently input overlaps with previously stored schedules when the user completes the setting of the new schedule, and informing the user of the existence of the conflicting schedules when there are conflicting schedules, resulting from the determination. Accordingly, the method enables the user to conveniently recognize and arrange the conflicting schedules.
摘要:
An optical pickup to reduce a focus offset by alleviating the effect of at least a part of a region of a beam whose intensity is high due to residual aberration on a signal detected by a photodetector (40) even when the aberration remains in a beam received by the photodetector (40) due to a phase difference introduced by a correcting element (20) to compensate for spherical aberration.
摘要:
An optical disc apparatus and a wobble signal detection method in which a light beam projected onto an optical disc and reflected by the optical disc is divided into at least four light regions (L1-4) in the direction corresponding to the radial direction (R) of the optical disc to detect the light regions, and a wobble signal is detected by performing a subtraction on first and second difference signals, the first difference signal obtained by performing a subtraction on detection signals for the inner light regions (L1,L2) of the divided/detected light beam and the second difference signal obtained by performing a subtraction on detection signals for the outer light regions (L3,L4) of the divided/detected light beam. Accordingly, when a wobble signal is reproduced from an optical disc manufactured by a wobble modulation manner, a wobble signal is prevented from being degraded due to the interference (cross talk) from the wobbles of adjacent tracks, even though the track pitch of the optical disc is reduced to improve the recording density.
