PURPOSE:To prevent deterioration is reproduced sound quality due to the wear of a magnetic tape by reproducing recording information after properly rewinding the magnetic tape on detecting the arrival of a customer, and by recording new guidance information on an unrecorded part of the tape. CONSTITUTION:Recording and reproducing head 5 is normally at the endmost part of the recorded part of a magnetic tape; after the magnetic tape is rewound properly in response to the output signal of detecting circuit 10 for the arrival of a customer, recording information is reproduced and new guidance information is recorded on the unrecorded part of the magnetic tape. For example, when the discrimination signal which indicates the start of a specific program is sent from turner 2 and then detected by discrimination-signal detecting circuit 9, microprocessor 15 controls the device to record the broadcast program on the magnetic tape. Simultaneously, the pulse signal that pulse generating circuit 14 generates corresponding to the extent of the movement of the magnetic tape is stored in microprocessor 15, thereby make the prescribed recording information reproduced when a customer arrives. |
