Title:
FIXED-HEAD MULTI-TRACK PCM SOUND RECORDING AND REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JPS6295771
Kind Code:
A
Abstract:
PURPOSE:To enable an automatic reversal reproduction and to facilitate the reproduction operation by including an identification code showing whether voice data sound recording in channels A and B are in the same direction or in the opposite directions when recording the signal such as a time code, a program, with frame constitution. CONSTITUTION:After recording a music or others in the channels A and B of a recording and reproducing circuit of CUE track, information such as a time code m2 or others in a CUE track edition circuit 25. The frames of the channels A and B based on said recorded information are alternately formed with a synchronizing signal m1, a code m2, a program m3, an error detecting code m0, the division mode bits of the channels A and B, and A/B-channel identification code bits, to enable the identification of the sound recording-direction. The frames are recorded in a magnetic tape 28, reproduced by a magnetic head 29, and demodulated and detected 31 in synchronization. A division-code-Ach/Bch-identification 32 (division mode detection) is executed, an Ach/Bch-sound recording-direction identification 34 for the sound recording and in the channels A and B is executed. As a result, the automatic reversal reproduction is enabled.
