Abstract
PURPOSE: To perform reading strong to jitter and skew by independently reading out the logics 0, 1 of the digital data having been recorded in two sets of tracks and combining the read-out signals from the respective tracks according to the presence or not of the change in polarity data.
CONSTITUTION: The logics 0, 1 of the digital signal D have respectively separately been recorded in the zero track 11 and 1 track 12 of a magnetic tape 10. These records are separately reproduced by a magnetic head, whereby the reading strong to jitter is accomplished. The presence or not of the change in the polarities of the reproduction signal in the search signal periods T1, T2 ... of about one and half times the inter bit spacing is detected at this reading. If the outputs are so combined that, when there is no change in the polarity at each bit, the read-out signal of the track 12 is outputted for the track 11 and when there is a change in the polarity at each bit, the read-out signal of the track 11 is outputted for the track 12, whereby reading strong even to jitters may be accomplished.
