摘要：
Digital data is formatted and recorded in track pairs on a tape by the rotary heads of a DAT so as to have a header portion for each track which includes a frame number, error correcting code, ID and so on added to the digital data, the content of each header portion of the tracks for any given frame being equal whereby it is possible to easily detect, upon reproduction, unerased data signals due to head clogging and so on by comparing portions of the two header portions of each frame and error correcting the data from those tracks where it is determined that the compared header portions contain different data.
