Disc reproducing apparatus and disc reproducing method

摘要

The present invention includes a playback means for playing back data on a disk; an audio output unit for outputting audio data as an audio signal to the outside when the audio data is played back by the playback unit; an audio level manipulation unit for manipulating the output level of the audio signal outputted from the audio output unit; a detection unit for detecting a set value of the audio level manipulation unit; and a rotation speed control unit for controlling the rotation speed of the disk which is played back by the playback unit on the basis of the set value detected by the detection unit only when no audio signal is outputted from the audio output unit. In this disk playback device, less influence is exerted upon the operation of the drive even when an erroneous operation is performed and the user can arbitrarily change the disk rotation speed by a simple operation without adding a new operation unit.
