ABSTRACT:
A disk recorder/player (1) including a skew adjusting means of a thin design is provided which includes a base (101), a disk rotation driving mechanism (102) for an optical disk (4), an optical pickup (103), first and second guide shafts (105, 106) to support the optical pickup (103) at opposite ends of the latter, an optical pickup moving means (104) guided by the first and second guide shafts (105, 106) in moving the optical pickup (103) radially of the optical disk (4), an elastic member (126) put in contact with the first and second guide shafts (105, 106) to force the first and second guide shafts (105, 106) in a direction generally perpendicular to the main side of the optical disk (4), an adjusting screw (127) put into contact with the first and second guide shafts (105, 106) from the opposite side of the elastic member (126) to move the first and second guide shafts (105, 106) in a direction opposite to the direction of forcing by the elastic member (126), and a skew adjusting means (109) which adjusts a skew, if any, by adjusting the inclination of the first and second guide shafts (105, 106) by the adjusting screw (127).
