The present invention relates to a system for reproducing information such as music recorded on a compact disc (CD) (hereinafter called digital disc).
In the LP record player, the tempo, pitch and tone of the reproduced music can be variously changed by manually changing the rotating speed of the turntable of the player.
For example, in a discotheque a disc jockey operates the turntable to produce the above described effect.
FIG. 1 is a block diagram showing a reproducing system according to an embodiment of the present invention;
FIG. 2 is a perspective view of a pulse encoder;
FIG. 3 is a rotating condition detecting circuit;
Referring to FIG. 1, the reproducing system of the present invention comprises a system controller A for controlling the whole of the system, a reproducing system B, a manipulating section C and a display D.
The system controller A has a microprocessor unit (MPU) For performing a system program, and controls the reproducing system B and display D in accordance with the user's operation of the manipulating section C.
The reproducing system B comprises a spindle motor 2 for rotating a CD 1, a pickup 3, a PLL (phase-locked loop) 4, a signal processing circuit 5, a digital signal processor (DSP) 6, a D/A converter 7, and an output circuit 8.
