It is assumed that a timer recording reservation for recording (checkout) has been made.

  In step S10, the control unit 15 determines whether the timer activation time has come. The control unit 15 can check whether or not the timer activation time has come by checking the time of the setting unit 7. If the predetermined timer activation time is reached, the process proceeds to step S11. If the timer activation time is not reached, step S10 is repeated.

  Next, in step S11, the control unit 15 turns on the power of the audio device 1 and the MD recording / reproducing device 2. The power of the MD recording / reproducing apparatus 2 can be supplied via the power cable 5.

  Next, in step S <b> 12, the control unit 15 transmits / receives a signal for confirming a predetermined setting when the MD recording / reproducing apparatus 2 is activated via the USB cable 3.

  Next, in step S <b> 13, the control unit 15 transmits a recording command signal to the MD recording / reproducing apparatus 2. The MD recording / reproducing apparatus 2 that has received the recording command signal records (checks out) predetermined music data in the HDD 10 of the audio apparatus 1 to the MD via the USB cable 3.

  As described above, the audio apparatus 1 can receive the recording data by transmitting the recording command via the USB cable 3 at the time set in the setting unit 7, and the MD of the MD recording / reproducing apparatus 2 can be received. Timer recording is possible.

  It should be noted that the music data stored in the HDD 10 of the audio apparatus 1 is not only recorded (checked out) as described above, but, for example, the music data recorded in the CD-ROM drive 11 is recorded. In addition, if the audio apparatus 1 includes a tuner unit, the sound from the tuner can be recorded. If the audio apparatus 1 includes an external input terminal, the externally input sound can be recorded in the same manner. You can also.

  As specific means, an audio signal from the tuner is recorded in the HDD 10 by the ATRAC 3 at a predetermined time, and the recorded signal is read and recorded in the MD recording / reproducing apparatus 2 via the USB cable 3 ( Check out).

  The audio apparatus 1 and the MD recording / reproducing apparatus 2 may include an interface such as a SPDIF (Sony Philips Digital Interface) for recording.
