光学デイスクプレーヤ。 In an optical disc player that plays back an optical disc, and especially a language practice optical disc player that plays back a language practice optical disc to which a lesson index number has been added, the index number of the audio data being played is stored for a predetermined period of time. A holding means for holding the index number with a delay, and means for generating a track jump signal targeting the index number held in the holding means when the repeat signal is supplied, and supplying it to the drive circuit of the optical pickup. , the repeat operation of the audio data section in the index section unit is characterized in that the repeat operation of the audio data section can be performed repeatedly from the time when a certain period of time has elapsed after the start of the playback of the audio data section to the point when a certain period of time has elapsed after the end of the playback. Optical disc player for language practice.
