Abstract
An information playback apparatus is provided to obtain sound effects by using an optical disc in much the same way an analog record is manipulated. A pressing pressure applied onto a rotatable jog dial is detected by providing a pressure sensing layer to the jog dial. When no pressing pressure is applied onto the jog dial, audio information is played back from an optical disc at a normal tempo. When an end of the jog dial at rest is pressed with a pressing pressure within a predetermined range, a tempo of a playback sound played from the audio information is changed in response to the pressing pressure. When an end of the jog dial at rest is pressed with a large pressing pressure, a tempo of a playback sound played from the audio information is changed in such a manner that playback of a playback sound is stopped eventually. When the pressing pressure is released from the jog dial at rest, a tempo of a playback sound played back from the audio information is changed in such a manner that a playback sound is eventually played back at the normal tempo. Also, a tempo of a playback sound is changed in various manners in response to a pressing pressure onto the jog dial by providing ma…
