[0045]
The I / F 205 is an interface for connecting the PC 2 to the recording / reproducing device 1 via the USB 3.
[0046]
Next, the operation will be described.
FIG. 3 shows the title check-out / check-in process by the recording / reproducing apparatus 1 and the title recording process by the PC 2 from the input of the song order and the title on the MD title editing screen of FIG. It is a time chart which shows a process.
[0047]
As shown in FIG. 3, the PC 2 performs bulk transfer of the empty music data, its metadata (including information on the music order and title), and the check-out instruction data to the recording / reproducing apparatus 1 in a lump (step). S1). The recording / reproducing apparatus 1 receives the data bulk-transferred from the PC 2 (Step S2), and checks out the received data to the memory card 5 (Step S3).
[0048]
Next, the recording / reproducing apparatus 1 reads the data in the memory card 5, records the read metadata on the MD4 (Step S4), and deletes the data recorded on the memory stick 5 (Step S5).
In step S4, the data checked out to the MD4 is music data and metadata including information on the music order and title. However, since the music data is empty data, the recording / reproducing apparatus 1 records the data on the MD4. Instead, the information of the title and the music order is recorded in association with the UTOC area in the MD4. Thus, the checkout of the title information to the MD4 is completed.
[0049]
Next, the recording / reproducing apparatus 1 temporarily switches the connection state with the PC 2 from ON to OFF by controlling the SW 106 in FIG. 1, and then switches the connection state ON again (step S5). Here, the PC 2 detects the connection state with the recording / reproducing device 1 (step S6), and when detecting the disconnection, the PC 2 transmits the check-in instruction data of the data in the memory card 5 to the recording / reproducing device. 1 (step S7).
[0050]
Subsequently, the recording / reproducing apparatus 1 receives the check-in instruction data from the PC 2, reads the data in the memory card 5, and transmits the data to the PC 2 (Step S8). When receiving the data in the MS from the recording / reproducing device 1, the PC 2 analyzes the received data. If the received data is empty, a checkout invalidation process is performed (step S9). That is, the PC 2 invalidates the checkout for the memory card 5 and does not add the number of checkouts. Subsequently, the recording / reproducing device 1 deletes the data in the memory card 5 (Step S10).
[0051]
As described above, the PC 2 performs bulk transfer to the recording / reproducing apparatus 1 of the metadata including the song order and title information input by the user, the empty music data, and the checkout instruction data for the MD 4. After temporarily storing the data received from the PC 2 in the memory card 5, the recording / reproducing apparatus 1 transfers the data in the memory card 5 to the MD4 and records the title information in the MD4. Further, the recording / reproducing apparatus 1 temporarily disconnects from the PC 2 and then reconnects. The PC 2 detects that the connection with the recording / reproducing device 1 has been disconnected, and transmits check-in instruction data of data in the memory card 5 to the recording / reproducing device 1. The recording / reproducing apparatus 1 reads data from the memory card 5 and transmits the data to the PC 2. The PC 2 receives the data in the memory card 5, analyzes the received data, and executes a process of invalidating the checkout to the memory card 5. Then, the recording / reproducing device 1 erases the data in the memory card 5.
[0052]
Therefore, the title can be input using the keyboard and the mouse of the operation unit 202 of the PC 2, so that the operability is improved. When inputting a title, a kana-kanji conversion program and a dictionary provided as standard equipment on a PC can be used, so that not only kana but also a title using kanji can be easily input. Further, since it is not necessary to install a kana-kanji conversion program or a dictionary in the recording / reproducing apparatus 1, it is possible to prevent an increase in cost.
[0053]
In addition, by specifying the music order, the title of the specific music data already recorded on the MD 4 can be recorded, and the degree of freedom in editing the title can be increased.
[0054]
Further, the configuration of the conventional audio system does not need to be largely changed, and the recording / reproducing apparatus 1 does not need a dedicated device for title input, so that the audio system 10 can be configured at low cost. It is convenient for the user because the labor and cost of purchasing the dedicated device are eliminated.
[0055]
Note that the present invention is not limited to the above embodiment. For example, a communication unit is provided in the PC 2, a program for realizing a CDDB (Compact Disc Data Base) connection function is installed, metadata including title information and data of title information are obtained from the CDDB, and checked out to the MD 4. You can also.
[0056]
Further, instead of the MD4, for example, a recording medium corresponding to the specification of the metadata area such as a hard disk may be applied, or in place of the memory card 5, a recording medium having a property that the data disappears when the data is read out. It is also possible to apply a medium.
[0057]
In the above embodiment, the data temporarily stored in the memory card 5 is automatically transferred to the MD 4 and the title information is checked out in the recording / reproducing apparatus 1. However, for example, the system controller 101 The presence or absence of data in the data may be periodically monitored, and if there is data, the data may be transferred to the MD4. If there is data in the MS, the presence of the data is displayed on the display panel unit 103 to notify the user, and after the user inputs a title writing instruction from the operation unit 102, the data in the memory card 5 is read. The data may be moved to the MD4.
[0058]
In addition, since the title information cannot be checked out when the MD4 is not inserted, the recording / reproducing apparatus 1 may display on the display panel unit 103 that the MD4 is not inserted. If the title in the song order specified by the metadata received from the PC 2 is already recorded on the MD 4, the title is overwritten with the newly specified title, and the fact that the title has been overwritten is displayed on the display panel unit 103. It is also possible.
[0059]
Further, in recent years, MSs having unique IDs are commercially available, but when an ID is recorded in advance in the MS of the above-described embodiment, the PC 2 transmits data from the memory card 5 to the memory card 5 before checking out. Of the title information to the MD 4 only when the ID is received together with the data in the memory card 5 from the recording / reproducing apparatus 1 at the time of check-in, and is matched with the ID at the time of check-out. It may be determined that the checkout has been completed normally.
[0060]
In addition, the detailed configuration and detailed operation of each device constituting the audio system 10 to which the present invention is applied can be appropriately changed without departing from the spirit of the present invention.
[0061]
【The invention's effect】
