ABSTRACT:
A magnetic recording device incorporating both a 2-channel recording mode and a multichannel recording mode in one piece of equipment and using recording heads in multiples of two. This magnetic recording device is provided with a head drum, a pair of magnetic recording heads W1+ and W2- of a head width Hw and arranged in mutual proximity and along the rotation direction of the head drum, and a pair of magnetic recording heads W1- and W2+ of a head width Hw/2 and arranged in proximity to the magnetic recording head W2-. These magnetic recording heads W1+, W2-, W1-, W2+ are positioned so that the upper edge of the magnetic recording head W1+, the lower edge of the magnetic recording head W2-, the upper edge of the magnetic recording head W1- and the lower edge of the magnetic recording head W2+ are on the imaginary common line along the rotation direction of the head drum. Information is recorded by the magnetic recording heads W1- and W2+ on both sides of the boundary line of the recording tracks of the recording tape medium previously recorded upon by the magnetic recording heads W1+ and W2-.
