6] (a total of 12).

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

The stocker 1 is displayed on the segment display section T.
1 and the remaining recordable time of the MD disk contained therein are displayed. Then, the remaining recordable time of another MD disc can be checked by using the operation key group 34 shown in FIG.

While referring to each of the above-mentioned indications, the user enters the CD
It is determined which song in the disc is to be recorded on which MD disc, 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 unit 31d in the memory unit 31 shown in FIG.

In this embodiment, as shown in FIG.
It is assumed that one recording program is set. The contents of the recording program can be confirmed based on the display as shown in FIG.

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

By displaying the contents of each recording program in the same manner as described above by operating the operation key group 34, the contents of the recording programs can be confirmed.

Next, the rearrangement processing unit 3 of the MD control unit 30
2c (see FIG. 2) is based on the recordable MD disk storage location information stored in the memory unit 31 so that the moving order of the stocker from the start of recording to the end of recording is minimized so that the moving distance of the MD disk is minimized. (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 on the playing order of each song (track) is transmitted to the CD reproducing device 50 via the. (S6).

As a result of the above processing, the contents of the recording program are changed from the state of FIG. 6 to the state of FIG. 7, and the data in the fourth memory unit 31d of the memory unit 31 is updated. Then, the contents of the updated recording program are displayed to notify 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 stops with the end of recording (S8 to S1).
0).

Next, with reference to FIG. 9, the process of determining the recording order of the MD disk in which the moving distance of the stocker from the start of recording to the end of recording shown in S6 of FIG.

The position facing the insertion hole 4 (ie, the front)
Is particularly called a front storage unit, and the number of the front storage unit (hereinafter referred to as a front storage number).
In the state of FIG. 1, the front accommodation number is “1” because the accommodation section [MD1] is located at a position facing the insertion hole 4.
This value is stored in the register R0 (P1), and the number of the accommodation section of the MD disk selected by the user to be used for recording is stored in the register R1 (P2).

Note that the numbers of the other storage units not at the front are simply referred to as storage numbers. For example, the accommodation number of the accommodation unit [MD4] is “4”.

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

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

Then, it is confirmed whether or not the calculation of the moving distance Q from the storage unit indicated by the register R0 to the storage unit indicated by the register R1 has been performed for all the storage units specified by the user's program (P5). If all the movements have been completed, the process proceeds to the next (P6), while if not completed, the process returns to the (P2) and the travel 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 accommodation part are obtained, and the minimum movement 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 in the clockwise direction among the MD disks accommodated in the rotary stocker 11 is stored in the memory.

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

It is confirmed whether the recording order has been determined for all the accommodation numbers designated by the user (P
9) When the recording order is determined for all the 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). The procedure returns to (P2) in order to determine the recording order again for the remaining accommodation numbers except for the accommodation number.

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

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

Then, it is determined whether the value of the register Q1 is larger than a half of the total number S of the accommodation units of the rotary stocker 11 (X3). If the value of the register Q1 is smaller than half of the total number S of the accommodation units, 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 storage units, the moving distance Q is equal to the total number S of the storage units.
Minus the value of register Q1 (X5).

On the other hand, in (X1), the register R
If the value of the register R0 is equal to or smaller than the value of the register R0, the value of the register R0 is further compared with the value of the register R1 (X6). 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 half the total number S of the storage units (X8). If the value of the register Q2 is larger than half of the total number S of the storage units, the moving distance Q is equal to the storage unit. (X10).

However, the value of the register Q2 is equal to the total number S of the accommodation units.
Is smaller than the value of (X9), the value of the moving distance Q remains the value of the register Q2.

On the other hand, in (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 disk to the MD disk. Therefore, the time required for recording can be reduced.
