Abstract: An optical recording/reproducing apparatus, an optical pickup, and a method for detecting a tracking error signal are provided to detect the tracking error signal with an excellent accuracy in near-field optical record/reproduction. An optical recording/reproducing apparatus comprises an optical pickup(100) and a controller. The optical pickup(100) is composed of a detector(120), an optical system(300), and a driver(107) for driving a condensing lens(104) having a numerical aperture of 1 or bigger. The optical system(300) applies light from a light source(101) onto an optical recording medium(90) as near-field light by the condensing lens(104), and introduces light reflected from the optical recording medium(90) toward the detector(120). The optical recording/reproducing apparatus(100) controls recording and reproducing processes based on the optical output detected by the detector(120). The optical system(300) includes a beam splitter(102) for reflecting both a P-polarized component and an S-polarized component of the reflected light, and a separator(110) for separating the P-polarized component and the S-polarized component reflected by the beam splitter(102). The detector(120) individually detects the P-polarized component and the S-polarized component separated by the separator(110).

Abstract: PROBLEM TO BE SOLVED: To remove an foreign material stuck to an objective lens in a disk unit with simple mechanism. SOLUTION: A tracking error detecting part 331 detects a tracking error signal based on a reproduced signal read out from an optical disk. When the tracking error signal is in a state in which it exceeds the supremum or the lowest limit of the prescribed amplitude range, it is estimated that a foreign material is stuck to an objective lens as a main cause, a tilt control part 342 performs tilt operation for a tilt adjusting part 343 to remove the foreign material. Confliction between the objective lens and the optical disk by tilt operation is not caused even in a near field system by operating gap servo by a gap servo control part 322.

Abstract: PROBLEM TO BE SOLVED: To provide an optical disk driving unit capable of properly controlling a gap by removing dusts on a disk, an optical disk device having the same mounted thereon, and its driving method. SOLUTION: Since the optical disk driving device 1 includes a contact type lens cleaning mechanism 60 and a disk cleaning mechanism 80, dusts are removed more easily as compared with the conventional art. Thus, gap servo control and initial tilt adjustment are properly carried out. In addition, needless to say, tracking servo control, tilt servo control, and the like are properly carried out.

Abstract: PROBLEM TO BE SOLVED: To provide an optical disk driving device capable of surely preventing a disk from colliding against a condensing element, an optical disk device loaded with the driving device, and a driving method thereof. SOLUTION: A tilt sensor 29 detects the tilt angle between an SIL (solid immersion lens) and a recording surface of the disk and outputs the detection signal to a peak detector 30. The peak detector 30 detects the peak value of the wobbling of the surface due to the input tilt angle. A servo control is then started in a position on the disk where the wobbling corresponding to the vicinity of the peak value detected by the peak detector occurs. As a result, even if the wobbling of the surface occurs in the rotating disk, the wobbling of the surface reaches the peak when starting the servo control and the speed of the wobbling becomes nearly zero. Accordingly, even if the wobbling of the surface occurs in the rotating disk, the SIL can be prevented from colliding against the disk. COPYRIGHT: (C)2007,JPO&INPIT
