Abstract

PURPOSE: To prevent a head part of stored music signals from being missed and an unnecessary silent part from being generated when recording is started, by recording the stored music signals together with sub code data when an apparatus is moved from a temporary stop to a recording mode. CONSTITUTION: A CPU 5 detects a track number or time data of input sub code data, and sends a control signal to a servo circuit 13, so that the apparatus is turned into a recording state. A music signal of a semiconductor memory 6 is read out by a memory control circuit 7, transmitted to an EFM/CIRC encoder 8, encoded in a recording format and recorded to a mini disc 12. During the recording, the CPU 5 sets the apparatus in a halt state when time information of the input sub code data are stopped. In this manner, when the apparatus is switched to start recording is determined by the track number or time information of the input sub code data and music signals stored in the memory 6 are recorded. Accordingly, a head part is is prevented from being missed and an unnecessary soundless part from being generated when the recording is started.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device for recording / reproducing digital signals.

[0002]

2. Description of the Related Art Conventionally, when a music signal based on a digital signal is recorded on an optical disk, an optical disk recorder is put into a recording pause state, a player outputting a music signal based on a digital signal is put into a playback pause state, and operation keys on the main body are set. Or, it is common to start recording and playback by operating the remote control operation keys to record on the optical disc, and at the end of recording, confirm that the input of the music signal has stopped, and then stop the recording using the operation keys on the main unit or the operation keys on the remote control. is there.

However, when recording and reproduction are started by such a method, recording and reproduction are rarely started at the same time, and therefore, missing of a music head and recording of an unnecessary silent portion may occur. , Have to record again. Further, when the recording is stopped by the above method, the recording of the unnecessary silent portion may occur, and after the recording is completed, the unnecessary silent portion must be erased by the editing operation.

[0004]

When the means for transitioning to recording and reproduction is performed by the operation keys of the main body or the operation keys of the remote controller, recording and reproduction are rarely started at the same time as the operation. Occurrence of missing parts and recording of unnecessary silent parts may occur. In such a case, there is a drawback that the recording has to be performed again.

When it is confirmed that the input of the music signal is stopped by the operation key of the main body or the operation key of the remote controller, the recording stop is delayed from the stop of the input of the music signal, and unnecessary silence is generated. Some records may be printed. In such a case, there is a drawback in that the unnecessary silent portion must be erased by an editing operation after the recording is completed.

When it is desired to obtain a copy of data to be recorded by synchro-recording with a digital signal, the cueing operation must be performed simultaneously on the reproducing side and the recording side, and it is inconvenient especially when performing remote control operations between different devices.

According to the present invention, the transition condition to the start of recording is determined by the track number or time information of the input subcode data, and the music signals stored in the semiconductor memory are sequentially recorded on the disc. Therefore, it is possible to reliably prevent the beginning of the music piece from being lost and the recording of the unnecessary silent portion from occurring at the start of recording.

Further, since the stop of the input of the time information of the subcode data is set as the condition for shifting to the recording stop and the recording is stopped, it is possible to surely prevent the recording of the unnecessary silent portion at the end of the recording. it can.
