Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a reproducing apparatus which is connected to a plurality of recording apparatuses so as to simultaneously record signals to be reproduced on the plurality of recording apparatuses.

Conventional technology, for example, compact disc (Compact Di
SC (hereinafter abbreviated as CD) player) When recording an audio signal played by a compact cassette recorder (hereinafter abbreviated as recorder), synchronization of the playback operation on the CD player side and the recording operation on the recorder side is performed. Conventionally, synchronous control using the following procedure has generally been adopted.

(1) First, the recorder transmits a ready signal indicating that it is ready for recording to the CD player.

(2) Upon receiving the ready signal, the CD player transmits a start signal to the recorder when it enters the playback state.

(3) The recorder starts recording operation upon receiving the start signal. When the start signal is no longer transmitted, the recorder stops recording.

In this way, between the CD player that is a playback device and the recorder that is a recording device, a control signal line that transmits a ready signal to the CD player side and a control signal line that transmits a start signal to the CD player side are used. Thus, synchronous control of the playback operation and the recording operation is performed.

Even when recording audio signals played by one CD player using two recorders, by using the two control signal lines mentioned above, the recording operation can be started and stopped at the same timing for the two recorders. is controlled. One of the recording devices is a recorder, and the other is a digital audio tape recorder.
The same applies to the case of echoer (hereinafter abbreviated as DAT).

Problems to be Solved by the Invention However, in the case of the conventional recording control described above, when recording onto a magnetic tape by a recorder, it is necessary to feed the first part of the magnetic tape as a leader part, and it is necessary to record multiple pieces of music. In some cases, we may create a blank section of several seconds between songs to skip song selection during playback.
By sharing the above two control signal lines, for example, a CD player can connect a CD player to a recorder in accordance with the recorder's recording timing.
, AT at the same time, an unnecessary blank portion will be created on the magnetic tape on the DAT side.

On the other hand, if synchronization control is performed to match the recording timing of the DAT, there will be problems such as the above-mentioned blank feed on the magnetic tape on the recorder side, which will not produce blank parts, and the blank parts between songs will be short. occurs.

In addition, in the above-mentioned connection refinement between the CD player, recorder, and DAT, if you want to synchronize the playback and recording operations between Korg and the DAT, you will need to create a new connection between the recorder and the DAT. It is necessary to connect the recorder's ready signal output terminal to the DAT's start signal input terminal, or to directly connect the DAT's ready signal output terminal to the recorder's start signal input terminal. It is.

Therefore, it is an object of the present invention to provide a recording/reproducing system that can control recording operations for a plurality of recording apparatuses simultaneously and with different start and stop timings for each recording apparatus, and that allows the recording apparatus to also have a playback function. In the case of a device, the object is to provide a playback device that also enables synchronous recording between recording and playback devices.

Means for Solving the Problems The present invention provides a reproducing apparatus which is connected to a plurality of recording apparatuses and allows each of the recording apparatuses to simultaneously record signals to be reproduced by itself, and which provides a method for detecting when preparation for a recording operation is completed.
