Abstract
A data recorder has a first recording mode in which a rotary head records, on a tape-shaped recording medium, main data related to main information by forming many parallel tracks in a first area of the medium which extends in the lengthwise direction of the medium; and a second recording mode in which the rotary head records on the medium only sub-code data which is other than the main data by repeatedly recording the sub-code data many times forming many parallel tracks in a second area which extends in the lengthwise direction of the medium and in parallel to the first area.
