摘要

A computer comprises a medium drive configured to reproduce data recorded in a video recording medium and an audio recording medium. When a reproduction switch is turned on if the computer is not powered, it is determined whether the video recording medium or the audio recording medium is loaded. If the video recording medium is loaded, the operating system is activated and the reproduction application is also activated.
