Claims

[Scope of Claim for Utility Model Registration] An optical disk to be inspected is attached to the rotating shaft of a spindle motor, a laser beam is irradiated onto the surface of the optical disk from the head section, and the reflected laser beam is received by the head section to generate light. A device for inspecting a disk includes: a base plate; a slide table that can move on the base plate while remaining parallel to the base plate; a first support plate 4 supported by three pillars and disposed on the base plate; a spindle motor mounted so that its axis of rotation is substantially perpendicular to the support plate; a second support plate 8 disposed on a slide table supported by three pillars; and this second support plate. a head mounted so that the laser optical axis is substantially perpendicular to the laser beam; and adjustment spacers inserted into the ends of the six pillars, and the thickness or number of the adjustment spacers can be adjusted. The rotation axis of the spindle motor and
Optical disk tester with parallel laser optical axis.
