  • a sound source used by a DJ or the like is a CD, and it is sufficient that the reproducing apparatus has a CD drive and can reproduce a CD.
  • the sound source is not limited to a CD, and a storage means equipped with an HD (Hard Disc) drive capable of storing a much larger amount of music files has become common. For this reason, DJs and the like are also demanded of playback devices that can use HD. As a response to such market demands, a playback device having both an HD drive and a CD drive has been put on the market.
