The control unit 30 uses the system communication control bus 60 connected between the CD control unit 51 and the MD control unit 30 shown in FIG.
The CD is stored in the first memory section 31a in the internal memory section 31.
The TOC information of the CD disc in the reproducing unit 52 is stored (S1 in FIG. 8).

Then, the disk accommodation information indicating the accommodation area of the recordable MD disk in the stocker 11 is stored in the second memory section 31b in the memory section 31, and the TOC information of each recordable MD disk is stored in the memory section 31. It is stored in the third memory unit 31c (S2).

However, the disk accommodation information indicating the accommodation area of the recordable MD disk and the TO of the MD disk are recorded.
If the C information has already been stored in the memory unit 31 at the time of the previous recording, that information may be used, so it may be possible to read the accommodation location information or TOC information of the MD disc at this point. .

Next, based on the TOC information obtained in S1 and S2, the number of tunes of the CD disc and the information of the recordable MD disc existing in the stocker 11 are displayed, for example, as shown in FIG. 4 (S3). .

In this example, there are 13 tracks [track 1 to track 13] on the CD disk, and a recordable MD disk is accommodated in the stocker 11 [MD
1, MD2, MD4, MD5, MD6, MD7, MD1
0 / MD11 / MD12 / MD13 / MD15 / MD1
6] (12 sheets in total).

The number at the back is hereinafter referred to as the accommodation number. For example, in the case of MD6, the accommodation number is "6".

The segment display section T has a stocker 1
The accommodation number of 1 and the remaining recordable time of the MD disc accommodated therein are displayed. Then, the remaining recordable time of another MD disk can be viewed by using the operation key group 34 of FIG.

While referring to each of the above displays, the user can
Which music in the disc is to be recorded in which MD disc is examined, and the operation key group 34 (see FIG. 1) is operated to set the recording program (S4 to S5).

A plurality of recording programs may be set instead of one. The determined recording program is stored in the fourth memory section 31d in the memory section 31 shown in FIG.

In this embodiment, a total of 6 as shown in FIG.
Suppose two recording programs are set. The contents of the recording program can be confirmed based on the display as shown in FIG.

That is, when the number of the recording program is 1 (see the leftmost number of the segment display portion T), the tune (track) 4 of the CD disc (see the CD music calendar display portion C) is stored in the stocker accommodation number 5 (MD5). ) M
Recording is performed as a new track 8 (see the number at the center of the segment display T) of the D disc (see the stocker music calendar display S), and if this recording is performed, the remaining time of the MD disc is 12:57 seconds. (See the number on the right end of the segment display portion T).

The contents of each recording program can be confirmed by operating the operation key group 34 to display the contents of each recording program in the same manner as described above.

Next, the rearrangement processing unit 3 of the MD control unit 30.
2c (see FIG. 2) is the recording order of the MD discs so that the stocker movement distance from the start of recording to the end of recording is minimized based on the accommodation location information of the recordable MD disc stored in the memory unit 31. (The process of changing the recording order will be described later in detail with reference to FIGS. 9 and 10) and the system communication control bus 60
The information of the performance order of each music (track) is transmitted to the CD reproducing device 50 via the. (S6).

As a result of the above processing, the content of the recording program is changed from the state of FIG. 6 to the state of FIG. 7, and the data in the fourth memory section 31d of the memory section 31 is updated. Then, the contents of the updated recording program are displayed to inform the user (S7).

When the user gives an instruction to start recording from the operation key group 34, recording from the CD disk to the MD disk is started and stopped at the end of recording (S8 to S1).
0).

Next, with reference to FIG. 9, the process of determining the recording order of the MD disc which minimizes the movement distance of the stocker from the recording start to the recording end shown in S6 of FIG. 8 will be described in more detail.

Position facing the insertion hole 4 (ie front)
The storage unit that comes to the front is specifically called a front storage unit, and the number of the front storage unit (hereinafter referred to as the front storage number).
In the state shown in FIG. 1, the accommodation section [MD1] is located at a position facing the insertion hole 4, so the front accommodation number is "1".
This value is stored in the register R0 (P1), and the number of the accommodating portion of the MD disk selected by the user for recording is stored in the register R1 (P2).

Incidentally, the numbers of other accommodation units that have not come to the front are simply referred to as accommodation numbers. For example, the accommodation number of the accommodation unit [MD4] is "4".

Then, the moving distance Q to the accommodating portion of the selected MD disk is calculated using the values of the registers R0 and R1. A method of calculating the moving distance Q will be described later (P3).

Next, the moving distance Q obtained in the above (P3) is saved in a predetermined register (P4).

Then, it is confirmed whether or not the calculation of the moving distance Q from the accommodation portion indicated by the register R0 to the accommodation portion indicated by the register R1 has been performed for all the accommodation portions designated by the user program (P5), If all have been completed, the process proceeds to the next (P6), while if not completed, the process returns to the above (P2) and the movement distance Q is continuously calculated.

Among the values of the moving distance Q obtained by the above calculation and stored in the predetermined memory, the value of the minimum moving distance Q and the accommodation number of the accommodating portion are obtained, and the minimum moving distance Q is obtained. If the accommodation number for the value of is not one, the accommodation number existing in the predetermined rotation direction (for example, clockwise) is stored in the memory (P7).

That is, of the two accommodation numbers, the accommodation number of the MD disk which is closer to the clockwise direction among the MD disks accommodated in the rotary stocker 11 is stored in the memory.

On the other hand, if the accommodation number for the value of the minimum movement distance Q is one, the accommodation number for the minimum movement distance Q is stored in the memory (P8).

It is confirmed whether or not the recording order has been determined for all accommodation numbers designated by the user (P
9) If the recording order is determined for all accommodation numbers, the process ends.

On the other hand, if all the recording orders have not been determined, the accommodation number stored in (P7) or (P8) is stored in the register R0 (this becomes the new front accommodation number), Since the recording order is determined again for the remaining accommodation numbers except the accommodation accommodation number, the process returns to (P2).

By the above processing, the recording order of all MD discs designated by the user is finally determined.

Further, FIG. 10 shows the algorithm for obtaining the moving distance Q in (P3) of FIG. 9 in more detail. First, the values of the register R0 and the register R1 are compared, and the register R1 registers the register R0.
When it is larger, the value obtained by subtracting the register R0 from the register R1 is stored in the register Q1 (X2).

Then, it is judged whether or not the value of the register Q1 is larger than half of the total number S of the accommodating portions of the rotary stocker 11 (X3), and when the value of the register Q1 is smaller than half of the total number S of the accommodating portions. Stores the value of the register Q1 as it is as the required moving distance Q (X4).

However, when the value of the register Q1 is larger than half of the total number S of the accommodation units, the movement distance Q is the total number S of the accommodation units.
The value of the register Q1 is subtracted from (X5).

On the other hand, in (X1), the register R
If the value of 1 is the same as or smaller than the value of register R0, the value of register R0 is further compared with the value of register R1 (X6). If the value of register R0 is larger than the value of register R1, register Q2 is registered. The value obtained by subtracting the register R1 from the register R0 is stored (X7).

Next, the value of the register Q2 is compared with the value of half of the total number S of accommodating portions (X8). If the value of the register Q2 is larger than half of the total number S of accommodating portions, the movement distance Q is Is the value obtained by subtracting the value of the register Q2 from the total number S of X (X10).

However, the value of the register Q2 is S
If it is smaller than the value of, the value of the moving distance Q remains the value of the register Q2 (X9).

On the other hand, in the above (x6), the register R
When the value of 0 is equal to or smaller than the value of the register R1, the moving distance Q becomes 0.

In this way, the contents of the program by the user shown in FIG. 6 are finally rearranged as shown in FIG. 7, and the program is recorded from the CD disc to the MD disc. Therefore, the time required for recording can be shortened.
