Abstract
PURPOSE:To measure an output of an emitted light beam from an optical head by only installing the titled cartridge to an optical disk device, by providing an optical head access window on a position corresponding to an optical head in the optical disk device in a box-shaped case having the same outside dimension as that of an optical disk cartridge. CONSTITUTION:A cartridge 1 has the same outside dimension as that of an optical disk cartridge of an object to be measured, and an optical head access window 4 of the center part is shielded with a cover 2 in a usual state. At the time of measuring an output of an optical head of an optical disk device by this cartridge 1, the cover 2 is opened by only installing this cartridge to the optical disk device which is set in advance to a test mode for a measurement, a light beam emitted from the optical head is emitted to a photodetector 3, and an output of the photodetector 3 passes through a lead wire 6 and transferred to a specific pin of a connector 5. Accordingly, by fetching its signal to the outside from this specific pin, a desired measurement can be executed.
