    摘要: A reproducing apparatus mixes the voice information from a microphone and the information reproduced from a recording medium in which a vocal signal plus an instrumental signal is contained as a first signal in a first channel and only an instrumental signal is contained as a second signal in a second channel. A first mixing circuit mixes the first signal and the second signal. The output of the first mixing circuit is mixed by a second mixing circuit with the voice information from the microphone. A control circuit or audio detecting circuit provides a control signal in accordance with the level of the voice information from the microphone. The control signal controls a selection control circuit to gradually and smoothly vary the mixing ratio of the first signal and the second signal when mixing these two signals.

    摘要: A first reproduction circuit reproduces a digital stereo audio signal from a signal which is read by means of a pickup from a disc loaded at a playback position, and a second reproduction circuit reproduces an analog audio signal from the signal read by the pickup. When the disc loaded at the playback position is identified as being a Laser vision Disc with Digital sound (LDD) disc, the stereo audio signal outputted from the first reproduction circuit is mixed with the analog audio signal outputted from the second reproduction circuit, such that a vocal portion of a reproduction can be reproduced together with an accompaniment portion of the reproduction, in a stereo mode.

    摘要: The present invention provides an information recording method and an information recording apparatus, which are capable of recording reproduction controlling information in information recording medium such as DVD. An operation portion designates a division timing in the audio information in case of dividing continuous audio information to record it in the DVD. A pickup records the audio information before the designated division timing and the audio information after the designated division timing in the DVD. A system controller repeats generating object recording sequence information in associated with the audio information before and after the division timing, respectively, to record them in the DVD every time when the division timing is designated.

    摘要: For a disk recording and/or reproducing apparatus which may use either constant angular velocity or constant linear velocity disks, speed compensation circuitry is provided which operates in accordance with RF signal information recorded on a surface of a disk. Irrespective of the nature of the disk being used (CAV or CLV), comparison circuitry within the apparatus provides reliable speed detection and compensation.
