Abstract
A pick-up angle adjustment apparatus in provided for adjusting an angle of an optical pick-up mounted in an optical disk apparatus. In the pick-up angle adjustment apparatus, a first guide shaft has a first length between a pair of ends thereof for guiding and supporting the optical pick-up. A second guide shaft has a second length between a pair of ends thereof for guiding and supporting the optical pick-up. A first adjustment member 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 is 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. A second adjustment member 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 is 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. A distance ratio of the first distance and the second distance is set equal to a length rati…
