Claim:
A recording and/or playback apparatus comprising: a base; a disk rotation driving mechanism which supports an optical disk and rotates the optical disk; an optical pickup which focuses a light beam emitted from a light source by an objective lens onto a recording surface of the optical disk and detects a return light from the optical disk; a guide means having a first guide shaft which supports the one end of the optical pickup and a second guide shaft which supports the other end of the optical pickup, the first and second guide shafts being disposed on the base in parallel to each other radially of the optical disk; an optical pickup driving means guided by the first and second guide shafts to move the optical pickup radially of the optical disk; and a skew adjusting means including an elastic member which provides a force to the first and second guide shafts in a direction generally perpendicular to the main side of the optical disk and an adjusting screw which is in contact with the first and second guide shafts from the opposite side of the elastic member, and which adjust a skew by adjusting the inclination of the first and second guide shafts by the adjusting screw.
