摘要
A method and apparatus for playback of a data recording disc which contains a CD area in which a signal such as an audio signals recorded in digital form and a video area in which a FM-modulated video signal is recorded with a digital audio signal superimposed thereon. The position of a data detection point of a pickup is monitored, and the equalization and amplifier gain of components of a digital demodulation system are automatically changed in accordance with playback being executed of the CD area or the video area, so that a single demodulation system is used for both digital signals from the CD area and digital signals from the video area. In addition, the frequency characteristics of components in servo systems which conrol the spindle motor, pickup carriage, etc. of the apparatus are automatically changed over for CD area and video area playback respectively, to provide stable servo control in spite of the high speed of rotation during video data playback.
