Information recording/reproducing apparatus

摘要

An information recording/reproducing apparatus determines whether ejection of an optical disk stored in an optical disk drive or in a changer is allowed when receiving a command for ejecting the optical disk to the outside. The information recording/reproducing apparatus allows the optical disk to be ejected only when judging that the ejection is allowed. When judging that the ejection is not allowed, the information recording/reproducing apparatus rejects the ejection. Prohibition of ejection of an optical disk on which information whose copyright is to be protected has been recorded enables the use of the information for private hobby and at the same time prevents pirated versions or the like from being produced, thus realizing copyright protection.
