Claim:
A pick-up angle adjustment apparatus for adjusting an angle of an optical pick-up mounted in an optical disk apparatus, the pick-up angle adjustment apparatus comprising: a first guide shaft that has a first length between a pair of ends thereof for guiding and supporting the optical pick-up; a second guide shaft that has a second length between a pair of ends thereof for guiding and supporting the optical pick-up, the second length being different from the first length; a first adjustment member that is operable for vertically moving one end of the first guide shaft so as to adjust the angle of the optical pick-up, the first adjustment member being capable of moving the one end of the first guide shaft by a first distance when the first adjustment member is operated by a given operation amount; and a second adjustment member that is operable for vertically moving one end of the second guide shaft so as to adjust the angle of the optical pick-up, the second adjustment member being capable of moving the one end of the second guide shaft by a second distance when the second adjustment member is operated by the same operation amount as applied to the first adjustment member, wherein a distance ratio of the first distance and the second distance is set equal to a length ratio of the first length and the second length.
