摘要：
A rotary head type digital tape recorder in which a PCM signal and sub data for control and the like concerned with the PCM signal are recorded and/or reproduced by rotary heads. The invention relates to a method and apparatus for transmitting and/or receiving a digital signal in such a type of digital tape recorder by using a data format such that when the serial data is input and output each of a predetermined number of words of the reproduced PCM signal and each symbol of the reproduced sub data are transmitted as a pair synchronously with the rotation of the rotary heads. Thus, a large amount of sub data can be input and output together with the PCM signal.
