The cursor keys 43 to 46 are a plurality of types of keys for moving a pointer such as a cursor displayed on the output unit 9 in the up, down, left, and right directions.

  In the composite data recording / reproducing apparatus in the present embodiment, dubbing in both directions between the DVD 16b and the video cassette 20b is possible.

  The CPU 10 includes a determination unit 101 for determining whether or not the DVD 16b and the video cassette 20b can be recorded, and a direction determination unit 102 for determining a dubbing direction.

  When the determination unit 101 detects that the dubbing key 47 is pressed, the determination unit 101 determines whether or not each recording medium can be recorded based on signals from the DVD drive 16a and the VCR 20a. Specific determination for each recording medium will be described later.

  Based on the output from the determination unit 101, the direction determination unit 102 selects either the 'DVD → VCR' direction (DVD 16b to video cassette 20b) or the 'VCR → DVD' direction (video cassette 20b to DVD 16b). Decide on. When one medium is recordable and the other medium is unrecordable, the direction determining unit 102 determines the dubbing direction from a non-recordable medium to a recordable medium. If any recording medium can be recorded, the dubbing direction is determined based on an instruction from the user.

  Note that the operations of the determination unit 101 and the direction determination unit 102 may be realized, for example, by executing software stored in the storage unit 11, or at least one may be realized by hardware. .

  Here, the data to be dubbed is video data. However, the data is not limited to video data, and may be audio data or both. In the present embodiment, “dubbing” refers to re-recording recorded data recorded on one recording medium on another recording medium.

  FIG. 3 is a flowchart showing the dubbing process in the embodiment of the present invention. The process shown in the flowchart of FIG. 3 is stored in advance in the storage unit 11 as a program, for example, and the function of the dubbing process is realized by the CPU 10 reading and executing this program.

  Referring to FIG. 3, first, CPU 10 determines whether or not dubbing key 47 has been pressed (step S2). Wait until the dubbing key 47 is pressed (NO in step S2).

  If it is determined in step S2 that the dubbing key 47 is pressed (YES in step S2), the determination unit 101 determines whether or not the video cassette 20b is inserted based on the signal from the VCR 20a (step S4). . If it is determined that video cassette 20b is inserted (YES in step S4), the process proceeds to step S6. On the other hand, when it is determined that the video cassette 20b is not inserted (NO in step S4), it is determined that dubbing is not possible (step S22), and this process is terminated.

  In step S6, the determination unit 101 determines whether or not the inserted video cassette 20b is recordable, for example, whether it is a “claw-breaking tape”. If it is determined that the tape is a nail break tape (YES in step S6), the process proceeds to step S8. On the other hand, when it is determined that the tape is not a claw break tape (NO in step S6), the process proceeds to step S14. The “nail-breaking tape” refers to a tape in which a nail provided on the back of the video cassette 20b is folded to prevent erroneous erasure.

  In step S8, the determination unit 101 next determines whether the DVD 16b is inserted based on the signal from the DVD drive 16a. If it is determined that DVD 16b is inserted (YES in step S8), the process proceeds to step S10. On the other hand, when it is determined that the DVD 16b is not inserted (NO in step S8), it is determined that dubbing is not possible (step S22), and this process ends.

  In step S10, the determination unit 101 determines whether the inserted DVD 16b is a recordable disc.

Here, an example of criteria for determining whether or not a disc is recordable is shown below.
(1) Is it a DVD-Video disc?
(2) Whether the disc is finalized even in the DVD-R / RW Video mode,
(3) Whether the remaining recordable time is a predetermined time (for example, 30 minutes) or less even in a DVD-R / RW Video mode that is not finalized.

  If any one of the above (1) to (3) is applicable, it is determined that recording is impossible, and if none of the above is applicable, it is determined that recording is possible.

  Here, “finalize” refers to the final processing of recorded information so that it can be played back on many devices (to ensure compatibility), and writing is impossible after finalization. is there.

  Note that the user may be able to set a criterion for determining whether or not recording by the determination unit 101 is possible. For example, a menu that can set a predetermined remaining time may be provided. In the present embodiment, as shown in (3), whether or not recording is possible is determined based on whether or not the remaining recordable time is “predetermined time”. However, different times may be provided depending on the image quality mode. Good.

  If it is determined in step S10 that the disc is a recordable disc (YES in step S10), the direction determining unit 102 determines the dubbing direction as the 'VCR → DVD' direction. Then, dubbing is started according to this direction (step S12). The dubbing operation from the video cassette 20b to the DVD 16b can be realized by a known method. When the process of step S12 is completed, the dubbing process is terminated.

  On the other hand, if it is determined in step S10 that the disc is not a recordable disc (NO in step S10), it is determined that dubbing is not possible (step S22), and this process ends.

  In step S14, the determination unit 101 determines whether or not the DVD 16b is inserted, as in step S8. If it is determined that the DVD 16b is not inserted (NO in step S14), it is determined that dubbing is not possible (step S24), and this process ends. On the other hand, when determining unit 101 determines that DVD 16b is inserted (YES in step S14), it subsequently determines whether or not the inserted DVD 16b is recordable (step S16).

  If it is determined in step S16 that the inserted DVD 16b is not recordable (YES in step S16), the direction determining unit 102 determines the dubbing direction as 'DVD → VCR'. Then, dubbing is started according to the determined direction (step S18). The dubbing operation from the DVD 16b to the video cassette 20b can also be realized by a known method. When the process of step S18 is completed, the dubbing process is terminated.

  If it is determined in step S16 that the inserted DVD 16b is recordable (NO in step S16), dubbing is possible in any direction, so the direction determining unit 102 displays a setup menu, for example. And waits for a dubbing direction instruction from the user. When an instruction is input from the user, the dubbing direction is determined in the direction based on the instruction. Then, dubbing is started in the determined dubbing direction (step S20). When the process of step S20 ends, the dubbing process ends.

  As described above, the composite data recording / reproducing apparatus in the embodiment of the present invention can automatically determine the dubbing direction by the one-touch operation of the dubbing key 47 by the user, and can start dubbing in the determined direction. Thereby, the user's trouble of setting the dubbing direction can be saved. Further, the user can start dubbing without having to be aware of the dubbing direction, and convenience is improved.

  In steps S22 and S24, the CPU 10 may display a message “dubbing is impossible”. Further, the reason why dubbing is impossible may be further displayed. As a result, the user can easily take a dubbing action.

  In this embodiment, dubbing is started immediately in the dubbing direction automatically determined in S12 and S18. However, dubbing may be started in the determined dubbing direction in each step. May be displayed. In this case, for example, a message such as “Start dubbing after 5 seconds. Press the stop key if canceling” may be displayed and wait for an instruction from the user. By doing in this way, it can prevent dubbing starting in the dubbing direction which a user does not intend.

  In this embodiment, the dubbing between the tape medium and the disk medium has been described. However, the present invention is not limited to this as long as it is a detachable recording medium.

  Instead of the DVD 16b, for example, an optical medium or the like in which a program is recorded can be read by a drive device, and the program in the storage unit 11 can be updated.

  Further, the dubbing processing method performed by the composite data recording / reproducing apparatus of the present invention can be provided as a program. Such a program can be recorded on an optical medium such as a CD-ROM (Compact Disc-ROM) or a computer-readable recording medium such as a memory card and provided as a program product. A program can also be provided by downloading via a network.

  The provided program product is installed in a program storage unit such as a hard disk and executed. The program product includes the program itself and a recording medium on which the program is recorded.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
