In addition, the cost can be reduced.

[Conventional technology]

Conventionally, in a DAT (Digital Audio Tape Recorder), by pressing a recording mute button for recording mute (silent recording) during recording or during recording standby (pause in a recording state), a tilted track is recorded. PCM
Silent data was recorded in the data area. In addition, not only can the recording mute be performed for a predetermined time by a single press of the recording mute button, but also the recording mute button is continuously pressed, and the count value of the counter displayed on the display unit or the like is checked. I was As a method of resetting the counter, the recording mute button is pressed after the counter is reset, or the count value of the counter when the recording mute button is pressed is set by the user (hereinafter, a person who uses the DAT is referred to as a user). The recording mute time is calculated by referring to the count value at any time, and the recording mute button is released when the desired recording mute time is reached.

[Problems to be solved by the invention]

As is apparent from the above, in order to mute the recording only for the recording mute time desired by the user, clear the count value of the counter or store the count value at the time when the recording mute button is pressed, and The count value must be checked from time to time to calculate (in this case, mental arithmetic) and determine the time at which the desired recording mute time has been reached.

Further, if a display unit for displaying the recording mute time is newly provided, the configuration becomes complicated and the scale becomes large.

In view of the above, the present invention enables the user to grasp the recording mute operation time, thereby making it possible to specify the length of the recording mute reliably and easily, and to simplify and reduce the size of the configuration. It is intended to propose a recording / reproducing apparatus which can perform the recording and reproducing.

This can be performed easily, and the configuration can be simplified and downsized.

〔Example〕

Hereinafter, an example in which an embodiment of the present invention is applied to a DAT will be described in detail with reference to FIGS. 1 to 5.

FIG. 1 is a schematic view of a panel of a DAT according to the present invention. In the figure, (1) is a display unit, (2) is a tape drive mode switching selection unit, and the tape drive mode switching selection unit (2) has a cassette tray opening button (2a), a stop button (2b), and a reproduction button. Button (2c), recording button (2d), pause button (2
e), RM (recording mute) button (2f), tape fast forward (F
F) A fast forward button (2g) and a rewind button (2h) used for rewind (REW), an AMS (automatic music scan) fast forward button (2i), and an AMS rewind button (2j) are provided. There are other various buttons, but they are not directly related to the present invention, and therefore the description thereof is omitted.

The input section (4) including the tape drive mode switching selection section (2) and the display section (1) are connected to a CPU (5) having a RAM and a ROM therein as shown in FIG. The CPU (5) is connected to an audio signal and subcode signal recording / reproducing circuit section (6) and a system drive control section (7).

The recording / reproducing circuit unit (6) has at least an A / D, D / A conversion circuit (6a), an encoder, a decoder (6b), a recording / reproducing amplifier (6c), and a rotating head (6d). (7) has at least a reel drive control circuit (7a), a capstan servo circuit (7b), and a rotating drum servo circuit (7c).

Then, according to the input signal from the input unit (4), the CPU
(5) is operated, and the recording / reproducing circuit section (6) and the system drive control section (7) are controlled.

FIG. 3 shows a certain recording state (excluding the margin display section (1d)) of the display section (1) of the DAT according to the present invention. In FIG. 3, (1a) shows input during recording or reproduction. It is a digital display section of a margin indicating a margin of a signal or an output signal up to a maximum allowable level (0 dB). The digital display section (1a) of this margin displays the "MA
When "RGIN" is lit, it is expressed in dB as shown in FIG. 4A. However, when an RM (recording mute) button (2f) described later is pressed, "MARGIN" turns off and as shown in FIG. 4B. The display changes to a second (s) indicating the operation state of the recording mute.

Next, the setting of the recording mute operation time will be described with reference to the flowchart of FIG.

First, in step ST-1, it is determined whether or not recording is in progress or in a recording standby state. To enter the recording state, press the record button (2d) described with reference to FIG. 1 and then press the play button (2c) or the pause button (2e). Press (2d). And if YES, step S
Move to T-2. If NO, the determination is made again in step ST-1.

In step ST-2, it is determined whether or not the RM button (2f) has been pressed. If YES, the process proceeds to step ST-3. If NO, the process proceeds to step ST-9.

During the recording mute operation in step ST-3, that is, in step ST-2, the user presses the RM button (2f), but it is determined whether or not the pressed state is continued.
If S, the process proceeds to step ST-4, and if NO, the process proceeds to step ST-6.

In step ST-4, the count of the recording mute operation time, that is, the CPU (5) counts the recording mute operation time. Then, the process proceeds to the next Step ST-5.

In step ST-5, the count value counted by the CPU (5), that is, for example, the time (seconds) is added and displayed in 1/10 seconds like a clock as shown in FIG. 4B. . Then, the process returns to step ST-1.

In step ST-6, it is determined whether or not the recording is on standby.
If S, the process proceeds to step ST-7, and if NO (ie, during recording), the process proceeds to step ST-8.

In step ST-7, a recording mute operation, that is, silent recording by mute recording is started. And step ST
Move to -4.

In step ST-8, mute recording, that is, silent recording is performed. Then, the process proceeds to step ST-4.

In step ST-9, the counting of the recording mute operation time is stopped, and the value is cleared. Then, the process proceeds to step ST-10.

In step ST-10, the margin display section (1a) described with reference to FIG. 3 is switched to the display of the margin as shown in FIG. 4A, and the margin is displayed. And step ST-
Move to 11.

In step ST-11, it is determined whether or not recording is in progress. If YES, the process proceeds to step ST-12.
Move to ST-1.

In step ST-12, the DAT is set to a recording standby state. Then, the process returns to step ST-1.

As is clear from the above, when the user is pressing the RM button (2f) on the margin display section (1a), the time is displayed, so that the user always checks the recording mute operation time, Therefore, recording mute work is sure,
In addition to being able to perform easily, simplification of the configuration,
The size can be reduced and the cost can be reduced.

It should be noted that the present invention is not limited to the above-described embodiment, but may take various other configurations without departing from the gist of the present invention.
