ABSTRACT:
Information reproducing and recording apparatus is disclosed which has a tape recorder mechanism, a disc recorder mechanism and an electric circuit for reproducing and recording and in which information obtained from the disc recorder mechanism is recorded on the side of the tape recorder mechanism in the state that the tape recorder mechanism and the disc recorder mechanism are in constant-speed forwarding and reproducing modes of operation, respectively. Switching of the disc recorder from a non-reproducing mode to the reproducing mode of operation is detected and, based on the detecting signal, the tape recorder mechanism is automatically changed over from a stop mode to the constant-speed forwarding mode of operation. Switching of the tape recorder mechanism from the stop mode to the constant-speed forwarding mode of operation is detected and, based on the detecting signal, the disc recorder mechanism is automatically altered from the non-reproducing mode to the reproducing mode of operation. Further, switching of the tape recorder mechanism from the constant-speed forwarding mode to, for example, the stop mode of operation is detected and, based on the detecting signal, the disc recorder mechanism is automatically switched from the reproducing mode to the non-reproducing mode of operation. Still further, switching of the disc recorder mechanism from the reproducing mode to the non-reproducing mode of operation is detected and, based on the detecting signal, the tape recorder mechanism is automatically switched from the constant-speed forwarding mode to the stop mode of operation, for example.
