摘要:
An apparatus records main information and sub information onto an information recording medium, which has a main recording area and a sub recording area. The apparatus is provided with an receiving device that receives the main information input from the external source; an accumulating device that accumulates the main information received by the receiving device; a recording device that records the main information and the sub information to the main recording area and the sub recording area, respectively; and a controller that determines whether or not an amount of the main information accumulated in the accumulating device is smaller than a predetermined amount, and that controls the recording device. In the apparatus, the recording device records the sub information to the sub recording area under a control of the controller if the controller determines that the amount of the main information accumulated in the accumulating device is smaller than the predetermined amount, and the recording device records the main information to the main recording area under a control of the controller if the controller determines that the amount of the main information accumulated in the accumulating device is not smaller than the predetermined amount.

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 signal is 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 woth digital signals from the CD area and digital signals from the video area. In addition, the frequency characteristics of components in servo systems which control 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.
