CONSTITUTION:A mini disk 16 is rotated by a spindle motor 15 whose rotation is controlled by a servo circuit 13 controlled by a system controller 2. The counter is incorporated in the system controller 2 and a counting operation is started at the time of starting the sound recording operation of power supply application. The memory is incorporated in the system controller 2 further and a set value corresponding to the sound recording time set by a user is stored in the memory. In response to the start of the sound recording operation, the counting operation of the counter is started and the set value of the memory is compared with a counter value and, when the values coincide with each other, the sound recording operation is completed and music information generated by the sound recording is written in an U-TOC area.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus,
In particular, the present invention relates to a recording / reproducing device in which music information generated by recording is written in a designated area.

[0002]

2. Description of the Related Art For example, in a mini disk (MD) device, music information (U-TOC) generated by recording is recorded in a storage medium. The recording of the U-TOC information is performed automatically or at the user's command when the recording of a series of units is completed. In such recording / playback, recording has no meaning until the U-TOC information is recorded. That is,
When the power supply is interrupted during recording, the information is recorded but the U-TOC information is not recorded, so that the information cannot be reproduced. A timer is usually used to control the recording time. For example, when recording an audio signal output from a source such as an FM tuner that outputs an audio signal in a recording device such as a mini disk device for an arbitrary time, it is recorded in the entire recordable area, and only the necessary portion is recorded. Use a recording device such as a bare disk or a mini disk device with a built-in timer function to set the playback start time and end time in advance on the source side with a timer and start recording on the timer on the recording side as well. It was necessary to set the time and end time.

[0003]

As described above, in the conventional recording / reproducing apparatus, when controlling the recording time by the timer, both the timers on the source side and the recording side must match. Since it is complicated and a power source is required even in the standby state, it is necessary to always keep the power on. Further, if the recording start timing and the ending timing of the source side and the recording side do not match, there is a problem that the music piece to be recorded on the source side cannot be completely recorded or a silent portion occurs.

It is an object of the present invention to provide a recording / reproducing apparatus capable of setting a recording time arbitrarily and at a reliable timing.

[0005]

In order to solve the above-mentioned problems, a recording / reproducing apparatus of the present invention has a function of starting a recording operation by inputting a power source or a function of starting a recording operation from a stopped state, and music information regarding recording. In a recording / reproducing apparatus for writing a recording medium into a recording medium, the recording / reproducing apparatus is provided with a counter for starting time counting from the recording / reproducing start timing, and a memory for setting a recording time value in advance. When it coincides with the time value, the recording operation is stopped and the music information resulting from the recording is written in the recording medium.

[0006]

In the present invention, the counting operation of the built-in counter is started from the recording / playback start timing, and when the count value matches the preset setting value, the recording operation is stopped, and the song information caused by the recording is recorded. Is written on the recording medium.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of a recording / reproducing apparatus according to the present invention, which is applied to a mini disk device. The mini disk 16 is rotated by the spindle motor 15 whose rotation is controlled by the servo circuit 13 which is controlled by the system controller 2. The magnetic head 10 is activated by the drive circuit 9 and information is recorded on the mini disk. The optical pickup 12 is the servo circuit 1
It is driven by the sled motor 14 through the control of No. 3, and the reproduction signal read from the mini disk is sent to the RF amplifier 11. The EFM / ACIRC circuit unit 8 includes an RF amplifier 1
1 connected to the well-known EFM / ACIRC encoding,
Performs decoding processing. The system controller 2 receives an instruction signal from the key input unit 1 or the remote control light receiving unit 17, and controls the entire apparatus. The memory controller 6 controls writing and reading to and from the DRAM 7 as a memory. The ATRAC circuit unit 5 performs ATRAC decoding and encoding processing on the reproduction signal and the input recording signal. A
The / D converter 3 converts the audio input as a recording signal into a digital signal and sends it to the ATRAC circuit section 5, and the D / A converter 4 converts the reproduction signal from the ATRAC circuit section 5 into an analog signal for audio. Output as output. The backup power supply 18 is a battery that supplies power for backup in the event of a power failure or the like.

In the configuration of FIG. 1, let us consider a case where the recording operation is set in advance after the power is turned on. That is, let us consider a case where the recording operation is started when the power is turned on. A counter is built in the system controller 2, and the counting operation is started when the power is turned on (recording operation is started). The system controller 2 further has a built-in memory, and the set value corresponding to the recording time set by the user is stored in the memory.

In response to the start of the recording operation, the counting operation of the counter is started and the set value of the memory is compared with the counter value. Then, when the counter value and the set value of the memory match, the recording operation is ended, and the music information generated by this recording is written in the U-TOC area. In this way, it is possible to record for an arbitrary time without using a timer.

If the setting condition of the device is confirmed when starting the recording operation, the recording time from the stopped state can be set arbitrarily.

FIG. 2 shows a flowchart of the operation processing procedure of the above embodiment. First, a recordable time (Remain Time) indicating a recordable area (remaining area) in the recording medium is set as the parameter X1 (step S1), and the parameter X2 is set as X1 (step S1).
2) The presence / absence of a key input from the key input unit 1 is determined (step S3). Here, if there is no key input, the process returns to step S3, and if it is determined to be present, the type of key input is determined (step S4), and if it is determined not to be the key input for instructing the recording system. If it is determined that the input is a key input for instructing a recording system, it is determined whether or not a recording time (Rec Time) is designated (step S5). If the recording time is designated, the recording time set as the parameter X2 is set (step S6), and the start of recording is determined (step S7). In step S5, the recording (RecT
If there is no designation of time), the process proceeds to step S7.

If the recording is not started in step S7, the process returns to step S3. If the recording is started, the counter value is reset and X3 is set to zero (step S8), and then the count value X3 is set to 1 It is incremented by one (step S9). Next, it is determined whether the designated recording time or the value of the time Z obtained by subtracting the counted up time from the recordable time is positive or negative (step S1).
0).

If Z is positive, the process returns to step S9. If Z is negative or equal to zero, the recording operation is stopped (step S11) and then U-TOC is written (step S11). 12), the process ends.

On the other hand, when the power is turned on, step S1
Similarly, the recording time is set as the parameter X1 (step S13), the type of the timer switch is determined (step S14), and if the timer switch is a recording type timer switch, the presence or absence of the data of the parameter X2 is determined (step S1).
5). If the recording time is not specified, that is, if there is no X2 data, the parameter X2 is set to the recordable time X1 (step S16) and recording is started (step S1).
7) and the process proceeds to step S8. Step S14
In, if it is determined that the timer switch is a timer switch other than the recording system, the operation shifts to the determined other mode operation. In step S15, X
If the data of 2 is present, the process directly proceeds to step S17.

FIG. 3 shows a flowchart of a processing procedure when the recordable time corresponding to the recordable area of the recording medium is used. In FIG. 3, step processes having the same step numbers as in FIG. 2 indicate similar processes. In FIG. 3, after the process of step S1, the parameters X2 = X1 and X3 = 0 are set (step S3).
1), the process proceeds to step S3. In step S6, after setting X2 to the recording time, X3 = X1-X
It is determined whether 2 is positive or negative (step S32), and if negative, the process returns to step S6, and if positive or zero,
The process moves to step S7. In step S33,
The parameter X1 is decremented (decreased) by 1 and the parameters X1 and X3 are compared (step S34). If X1 is larger than X3, the process returns to the decrement processing of step S33. If X1 is smaller than X3 or equal, recording is performed. The process to stop (step S11) is reached.

On the other hand, if it is determined in step S14 that the switch is a recording type timer switch, the parameter X
The presence or absence of the data of 3 is determined (step S35), and if there is, the process proceeds to step S17, and if not, X3 =
After setting to 0 (step S36), the process proceeds to step S17. In step S15, it is determined that there is X2 data, and after it is determined in step S16 that X2 = X1, X3 = X1-X2 is set (step S37), and the recording start processing (step S17) is performed.
