Multi-channel recording and reproducing device
专利汇可以提供Multi-channel recording and reproducing device专利检索，专利查询，专利分析的服务。并且PURPOSE:To reduce probability by which synchronizing patterns of plural tracks make an error simultaneously due to drop-out, by dispersing the synchronizing patterns on a tape, when recording and reproducing an analog signal of a voice, etc. CONSTITUTION:One example of a recording format on a tape is shown. In this example, a case of recording to eight multi-tracks is shown. For instance, when width of a tape is 1/8 inch (3.2mm.), width of one track becomes about 400mum. For instance, in case when length of one frame is about 4.8mm., it will do that recording is executed at a distance of >=1/4 of one frame (L). In this case, synchronization of a CH1 and a CH5 forms a line on a vertical line. As for a circuit, 21-26 show shift registers using a flip-flop, and a step number of the shift register is selected as mentioned below. In case when length of one frame of one channel is N bit, it will do that the step number of the shift register 21 and 24, 22 and 25, and 23 and 26 to N/4, N/2 and 3N/4, respectively.，下面是Multi-channel recording and reproducing device专利的具体信息内容。
