摘要： An optical disk apparatus includes a tilt detection unit detecting the tilt value of an optical disk medium with respect to an optical system. A tilt compensation unit compensates for the tilt of the optical disk medium by adjusting a relative angle between the optical system and the optical disk medium according to the tilt value detected by the tilt detection unit. A tilt detection error estimation unit estimates tilt detection error of the tilt detection unit with respect to a radial position of the optical disk medium at which information is recorded/reproduced by the optical systems by referring to tilt values that are previously detected at a plurality of radial positions of the optical disk medium by the tilt detection unit. The tilt compensation unit has a correction unit that corrects the tilt value according to the tilt detection error estimated by the tilt detection error estimation unit. The tilt compensation unit compensates for the tilt of the optical disk medium according to the tilt value corrected by the correction unit.

摘要： A loading mechanism includes a frame and a tray on which an information recording medium is placeable. The tray includes a groove part and is movable between a first position where the information recording medium is contained completely inside the frame and a second position where the information recording medium is exposed completely outside the frame. The loading mechanism further includes at least three projections arranged on the frame at predetermined intervals along the sliding directions of the tray. The projections include first and second guide and support parts forming the first and second ends of the arrangement of the projections. The first and second guide and support parts come into substantially point or linear contact with the groove part of the tray so as to guide and support the tray when the tray is in the second position.

摘要： A loading mechanism for moving a tray between the outside and the inside of a recording and reproduction apparatus is disclosed. The loading mechanism includes a groove part and a projecting part for guiding the tray. The groove part is provided to one of the tray and a holding member holding the tray. The projecting part is provided to the other one of the tray and the holding member so as to fit with the groove part with play being provided therebetween. The amount of the fitting of the groove part with the projecting part differs between first and second positions, the first position being more distant from the center part of a portion of the tray on which portion an information recording medium is placed than the second position.
