Title:
MAGNETIC RECORDING AND REPRODUCING APPARATUS
Document Type and Number:
Japanese Patent JPH04206072
Kind Code:
A
Abstract:
PURPOSE:To avoid the deterioration of the quality of the sound of an audio signal by recording a digital audio signal and a digital video signal at the transmission speed which is twice the normal speed. CONSTITUTION:A digital audio signal DA1 and a digital video signal DV1 are alternately synthesized so that the signals endures for a specified period in synchronization with the operation of a digital audio tape recorder 13. Therefor, the transmission speed is twice in comparison with that of an ordinary digital audio tape recorder. The digital audio signal DA1 and the digital video signal DV1 are assigned into the right and left channels, and the recording signal DR is synthesized. At this time, the recording signal DR is outputted into the digital audio tape recorder 13 which is operated at the processing speed of twice the ordinary speed. The signal undergoes interleaving in the recorder. Thereafter, the signal is sequentially recorded in the magnetic tape together with detected error correcting code. Thus, the deterioration of the sound quality of the digital audio signal DA1 can be effectively avoided.
