PURPOSE:To obtain an audio signal independently of the speed difference of recording/playback of audio information and to make easy the operation, by setting a readout speed from a memory to reproducible value of the audio signal through the use of memories. CONSTITUTION:The tape speed of a deck 1 is set to a value suitable for types and speed of input signal of an input terminal 13 with the tape speed switching and control circuit 10. As a result, the speed of readout clock of the readout control circuit 24 of the memory 22 in interlocking with the circuit 10 is set. With this state, the recording condition of main data and audio information related to the index information or the like are given to a microphone 17, it is converted into a digital signal at an A/D converter 21 and written in the memory 22. The memory signal is sequentially read out based on the readout clock pulse in response to the tape speed from the circuit 24 and recorded on the tape 4. After the end of recording, the switch 11 is selected to the contact (b) to make the recording of main data in the set tape speed. The playback is made with the speaker information based on the write-in information of the memory 30 and the write-in control circuit 31. |
