Abstract

A digital information signal reproducing apparatus where the same first digital audio signal and second audio signal are doubly recorded on each of two tracks which are close to each other on a tape and where a digital information signal is reproduced from the tape by plural channel of rotary heads. The apparatus is equipped with head position control means for controlling so that a scanning position of the rotary heads coincide with the tracks at the time of variable speed reproduction when the tape is run at a different speed from that at the time of normal mode; detecting means for detecting that the rotary heads controlled by the head position controlling means jump over plural ones of the tracks; and means for performing a switching process of the first digital audio signal and the second digital audio signal for a predetermined period at the time of the jump and selecting one of the first digital audio signal and the second digital audio signal depending on an error state in a period other than the predetermined period, thereby preventing that error correction capability is lowered at the time of variable speed reproduction.
