A tilt adjusting apparatus for a disk drive including a support plate which is fixed to a drive plate, and a skew plate which is fixed to a spindle motor, wherein the support plate and the skew plate is attached to each other with guide screws. The skew plate is tiltably supported by the support plate with the use of helical compression springs. The skew plate has bulged portions which abut on gradient portions formed on support plate. The skew plate also has grooves for receiving guide pins which are fixed to the support plate. An adjuster screw applies force to the skew plate in a tangential direction which is perpendicular to the tracking direction of the optical pickup, and thus performs a tilt adjustment in the tangential direction.</PTEXT>
