ABSTRACT:
A data recorder comprises a first rotary head and a second rotary head which traces a tape-shaped recording medium travelling at a given speed by following recording tracks formed by the first rotary head. When an error of data reproduced from any of the recording tracks by the second rotary head is detected while data is being recorded by the first rotary head, the first rotary head is caused to record, in another track, data which is identical with the data reproduced from the above stated track depending on the data error occurring state of the track.
