[0018]

FIG. 1 is a block diagram of a disk drive according to an embodiment of the present invention. This disk device is a recording / reproducing player that performs both reproduction and recording of a mini-disc on which information regarding a recordable area is recorded. Further, the player of the present embodiment can be connected to a reproducing unit (not shown) of, for example, a compact disk as another recording medium.

As shown in FIG. 1, the spindle motor 24 of the player drives and rotates a turntable (not shown). The output from the non-contact pickup 26 is amplified by an RF amplifier 28 and then supplied to a servo circuit 30. Thus, servo signals such as a focus error signal and a tracking error signal are formed. And each servo signal is
It is supplied to the pickup 26, the feed motor 32 and the spindle motor 24.

The main signal output from the RF amplifier 28 is supplied to a signal processing system 34 as it is, and subjected to various known processes, and then a digital audio signal is supplied to a D / A converter 36. The digital audio signal is converted into an analog audio signal and supplied to the output terminal 38.

When an analog audio signal is input from the input terminal 40, it is converted into a digital audio signal by an A / D converter and supplied to the signal processing system 34. Thereafter, a recording signal is supplied to the head 44 and recorded on the disk 18 of the cartridge 18.

Further, a microcomputer (CPU)
Is connected to the input unit 10, and in addition to the power key, the reproduction key, the skip key, etc., the input unit 10 is used to program, for example, favorite songs on a compact disc in a desired order. A plurality of operation keys such as a program key 12 for setting the program mode and a recording key 14 as operation means are provided.

The input section 10 is provided with a receiving section 16, which receives an operation signal from a transmitting section 22 A of a remote controller (hereinafter simply referred to as “remote controller”) 22. This remote control 22 has "0"
The operation keys such as the number keys 23 to “9” are arranged, and information corresponding to the operation keys is input to the system controller 46 by operating the operation keys such as the number keys 23.

The system controller 46 causes the player to perform a predetermined operation by operating an input key of the input unit 10 or the remote controller 22. That is, the system controller 46 controls the input unit 10 or the remote controller 2.
The operation of the signal processing system 34 and the servo circuit 30 is controlled based on the operation signal of the second input key, and a part thereof has a judgment means.

The system controller 46 is connected to a display unit 48, and the display unit 48 has a TOC or UT
Information on the recordable area read from the OC, the title of the disc, the total number of songs, the total playing time, and the "recordable time" of the disc 18 are displayed, as well as the selected song number in the program mode, the playing time, and the programmed time. Number of songs,
The total playing time of the programmed music is displayed.

Further, the system controller 46 calculates the recordable time for recording on the mini-disc and, in addition to the recordable time and the instruction data from the numeric keys 23 of the remote controller 22 for indicating the track number of a compact disc (not shown). The playing time as recording data of the corresponding music (sound information) is calculated. That is, the system controller 46 cumulatively calculates (adds) the total playing time of the music selected in the program mode, and supplies the calculation result to the display unit 48.

Hereinafter, the processing of the player according to the present embodiment will be described with reference to the flowchart shown in FIG. First, this flowchart starts when the program key 12 is operated. That is, the user confirms that the player has been stopped, and
To enter Program mode. As a prerequisite for recording in the program mode, it is necessary that the mini-disc cartridge 20 is inserted into the player, and that the reproducing section of the compact disc and the player of the present embodiment are connected.

The calculation method according to the present embodiment is to cumulatively add the total playing time of the music selected in the program mode. Further, the disk 18 may be either a blank disk (a disk 18 having no recording portion) or a disk on which recording has been partially performed. That is, as long as there is a recordable area on the disk 18, the length of the recording time does not matter.

In step 100, a flag (Flag) indicating whether or not the total playing time of the program music is within the recordable time of the mini-disc is set to "0", and the timer is reset. Thereafter, in step 102, data of the song number of the compact disc and the reproduction time corresponding to the song number are fetched. In step 104, the "recordable time" of the disk 18 is calculated from the TOC information of the disk 18 shown in FIG.

In step 106, it is determined whether or not instruction data indicating the track number of the compact disc has been input.
That is, here, it is determined whether or not the numeric key 23 of the remote controller 22 has been operated. If step 106 is affirmative, data of the playing time of the song corresponding to the song number is fetched in step 108, and if step 106 is negative, it waits until the numeric key 23 is operated.

In step 110, the total playing time of the music selected in the program mode is calculated. Then, in step 112, it is determined whether or not the total playing time in the program is within the recordable time. That is, it is determined whether or not the total playing time T1 of the program music exceeds the recordable time (74 minutes in this example) T2 of the disk 18. If the total performance time T1 is within the recordable time (T1 <T2), the "total performance time" is displayed in step 114, and
In step 16, the process waits for input of the numeric key 23, and if there is an input, the process returns to step 108. Then, in step 110, this process is repeated while updating (adding) the “total performance time”.

If it is determined in step 112 that the total playing time T1 exceeds the recordable time T2 (T1> T
2) In step 118, the flag is set to "1", and in step 120, "Full" and "total playing time" are alternately displayed on the display unit 48. In this way, a warning is given that the total performance time T1 exceeds the recordable time T2, and the input total performance time T1 is reported, so that it is possible to recognize how much the total performance time exceeds the recordable time. In addition, the user can determine whether or not it is within the trouble-free range. Here, the display contents do not necessarily have to be alternately performed, and may be changed as appropriate, such as displaying both at the same time, expressing the Full by a color, and displaying the “total playing time” in a different color from the previous one. Applicable even if added.

Then, in step 122, a timer is started. In step 116, when the numeric key 23 is not operated, and in step 122,
After the timer starts, it is determined in step 124 whether or not the stop key has been operated. Step 124
If the answer is affirmative, in step 126, the program music input last is erased, and in step 128, the "total playing time" after erasing the last music is calculated and updated. The “total performance time” updated in step 130 is displayed on the display unit 48, and the process returns to step 106.

If step 124 is negative, step 1
It is determined at 32 whether or not the recording key 14 has been operated. If the answer at step 132 is affirmative, the program programmed at step 134 is recorded on the disk 18 in the order of the program.

If step 112 is negative,
Since the display 48 shows that the total performance time T1 exceeds the recordable time T2 as processed in step 120, the display in step 124, 1
32. That is, if the user operates the stop key in step 124, the last program music is erased, and the total playing time T1 <recordable time T
2, and if the total performance time T1> the recordable time T2 is within the trouble-free range, the recording can be performed by operating the recording key 14 in step 132. As described above, since the number of determination points of the user is increased, the selection range of the recording state can be increased.

If step 132 is negative, step 1
At 36, it is determined whether the flag is "0" or "1". If the flag is "0", the total performance time T1 <the recordable time T2.
Returning to step 116, the system waits for input of the numeric key 23.

At step 136, Flag is "1".
If so, in step 138, it is determined whether a predetermined time has elapsed from the start by looking at the timer. Step 138
Is negative, the process returns to step 124 and waits for any operation. Here, while the Flag is "1", no operation other than the stop key, the recording key 14, the key for canceling the program mode, and the reproduction key is accepted. Therefore, it is possible to prevent the user from additionally inputting a song that cannot be recorded.

If it is determined in step 138 that the predetermined time has elapsed, the program mode is terminated. Of course, even when the flag is "0", the program of the last program entered in step 124 is erased,
The recording can be started by operating the recording key 14 at 32.

In any state, the flow is terminated by releasing the program mode and operating the reproduction key, and the mode can be released or the reproducing operation can be performed.

It should be noted that the "total performance time" input in step 110 is not added to the TO
Recordable time T2 of disk 18 read from C information
Is subtracted from the total playing time T1 to determine whether or not the remaining recordable time is not minus (negative).
In 4, the remaining recordable time may be displayed. In this case, it is possible to know how much remaining recording time is insufficient for the input total performance time.

Next, another embodiment will be described. In this example, the processing is the same as that of FIG.
In the program recording mode, which is the first mode, a blank portion (silent portion) for a predetermined time is provided in step 134 so as to prevent cueing during reproduction, such as when the interval between songs is narrow, or the like. Record as follows.

If it is determined in step 112 that the total playing time T1 has exceeded the recordable time T2, but the recording key 14 is operated in step 132, the program recording mode is switched to the manual recording mode in the second recording mode. Change the mode to the recording mode. In the manual recording mode, the source selected as the sound source is mechanically recorded, so no blank space is formed between songs.
The recording is made as played.

Since the recording mode can be changed by operating the recording key in this manner, desired recording can be performed without canceling the recording mode and operating again. Further, in this case, since a blank portion between music pieces is not formed for a predetermined time, recording can be performed for a little longer time.

In the above embodiment, the operation means is the recording key 14, but a dedicated key may be provided as the operation means of the present invention, or a plurality of keys may be used to operate the recording apparatus as in the above embodiments. Processing may be performed. Further, in the above embodiment, the disc is a mini-disc, but the present invention can be similarly applied to a disc in which information on a recordable area is recorded.

[0045]

As described above, according to the present invention, the recording mode is switched from the program mode to the manual mode by operating the operating means. Even when the recording data is interrupted in the middle, the recording can be performed in the order of input of the program by a simple operation.
